What is a high carbon steel project report?
A high carbon steel project report is a detailed project report (DPR) for a melt shop that turns scrap, sponge iron and pig iron into billets with roughly 0.6–1.0% carbon. It sets out the melting and casting route, machinery, raw material mix, licences, project cost, means of finance, five-year projections, DSCR and break-even.
Promoters use it to size the furnace and caster and raise a term loan; banks and investors use it to judge whether the plant can carry its debt.
Also known as: project report on high carbon steel, high carbon steel business plan, high carbon billet plant DPR, high carbon steel feasibility report.
High carbon steel project report: plant cost in India and returns
Our sample report models a melt shop casting 33 MT of high carbon billets a day, or 10,890 MT a year over 330 working days. It starts at 60% of capacity and reaches 80% in Year 5, selling billets at ₹46,200 per MT ex-factory.
| Land and site development | 118.48 |
|---|---|
| Building and civil works | 321.23 |
| Plant and machinery | 598.98 |
| Other fixed assets | 72.18 |
| Contingencies | 46.01 |
| Preliminary and pre-operative | 28.92 |
| Working capital margin | 126.07 |
| Total | 1,311.87 |
| Promoter's contribution (25%) | 327.97 |
|---|---|
| Term loan from bank (75%) | 983.90 |
| Cash credit limit (separate) | 378.22 |
| Total project cost | 1,311.87 |
Margins in billet making are thin. In Year 3 the sample earns an operating profit (EBITDA) of ₹472.27 lakh on sales of ₹3,521.83 lakh. DSCR, the cash available for repayment divided by the instalments due, dips to 1.25 in Year 2, when full repayments start.
Term loan at 10.5% with a 6-month moratorium and 54 monthly instalments. All figures are illustrative.
High carbon steel manufacturing process, from charge to billet
A billet plant for high carbon grades follows the same route as a mild steel melt shop, with tighter control at every stage. Most of the extra cost goes into a cleaner charge, ladle refining and slower cooling.
- Charge selection
Scrap is sorted by grade and mixed with sponge iron and pig iron so that copper, tin, sulphur and phosphorus stay within the buyer's limits.
- Induction melting
A medium frequency induction furnace melts the charge in batches called heats, and a sample from each heat goes to the spectrometer.
- Ladle refining
The ladle furnace brings carbon up to grade with recarburiser, trims manganese and silicon with ferro alloys and uses argon stirring to lift inclusions into the slag.
- Continuous casting
Steel is poured through a tundish into water-cooled copper moulds, with speed and secondary cooling set to limit centre segregation, a common defect in high carbon grades.
- Cutting and slow cooling
Billets are torch-cut to length and cooled slowly in covered stacks or pits, because fast cooling can crack high carbon sections.
- Testing and dispatch
Each heat is checked for chemistry and soundness, stamped with its heat number and sent to wire rod mills with a test certificate.
Induction furnace or arc furnace for high carbon billets?
Most small and medium Indian melt shops use induction furnaces. They cost less to install, start and stop easily and suit a charge rich in sponge iron. Their weakness is refining: an induction furnace has little active slag, so it removes almost no phosphorus or sulphur.
An electric arc furnace refines better and handles poorer scrap, but it needs a much larger investment and a heavier power connection. That usually puts it beyond a plant of 30–40 MT per day.
For high carbon grades, the induction route works only when paired with a ladle refining furnace, a spectrometer and disciplined charge buying. That is the route modelled in our sample report.
Billets alone or billets plus rolling: selling billets keeps the project smaller. Adding a wire rod mill captures more margin, but it roughly doubles the scope and brings IS 7904 certification for the rods.
Raw materials for high carbon steel billets
Raw materials are 67.8% of sales in our sample, so the charge mix decides profit more than any other line. Sponge iron is added because it is almost free of copper and tin, which dilutes the residuals that come with scrap.
| Raw material | Share of cost | Year 3 (₹ lakh) |
|---|---|---|
| Heavy melting steel scrap | 45% | 1,073.99 |
| Sponge iron (DRI) | 33% | 787.59 |
| Pig iron | 10% | 238.66 |
| Ferro manganese and ferro silicon | 7% | 167.07 |
| Carbon raiser (recarburiser) | 5% | 119.33 |
| Total | 100% | 2,386.64 |
Year 3 costs at 70% capacity, from our illustrative sample. Scrap and sponge iron prices move every week; your report uses current quotes.
Machinery for a high carbon steel melt shop
The induction furnace with its power panel is the largest item, at about a third of the machinery cost. The billet caster comes next.
| Machine | What it does | Sample cost (₹ lakh) |
|---|---|---|
| Induction furnace with power panel | Melts the charge in heats | 203.65 |
| Ladle refining furnace with argon purging | Sets carbon and alloys, cleans the steel | 95.84 |
| Billet continuous casting machine | Casts liquid steel into square billets | 131.77 |
| HT transformer and substation | Takes the high-tension power supply | 59.90 |
| EOT cranes and teeming ladles | Move liquid steel and billets | 47.92 |
| Fume extraction and bag filter | Captures furnace fumes and dust | 29.95 |
| Spectrometer and laboratory | Checks chemistry of every heat | 17.97 |
| Cooling water system | Cools furnace coils and caster moulds | 11.98 |
| Total plant and machinery | 598.98 | |

How many people does a high carbon steel plant need?
Melt shops run round the clock, so staffing is planned for three shifts. Our sample plant employs 90 people, with furnace, ladle and caster operators making up most of the skilled crew.
| Category | Number | Year 1 cost (₹ lakh) |
|---|---|---|
| Management, supervision and administration | 14 | 51.24 |
| Skilled workers and operators | 31 | 72.54 |
| Semi-skilled and unskilled workers | 45 | 70.20 |
| Total | 90 | 193.98 |
BIS licence and approvals for high carbon steel
The BIS licence takes the longest to arrange, and as of October 2026 billets cannot be sold without it.
| Billet standard | IS 14650:2023 under the Steel Quality Control Order; it replaced IS 8951 for billets meant for high carbon wire rods, with implementation from 28 September 2024 |
|---|---|
| Wire rod standard | IS 7904:2018 for high carbon steel wire rods, also under the QCO, if you roll and sell rods |
| Pollution category | Red category: state boards list steel units using induction furnaces as Red, so consent to establish and operate takes longer and needs fume control |
| Power | High-tension connection and substation sanctioned by the state distribution company for the furnace load |
| Factory and safety | Factory licence and fire NOC under the state's rules for the workforce and site |
| Business registration | Udyam (MSME) and GST registration |
Who buys high carbon steel billets?
Demand comes from mills that roll high carbon wire rods and from the wire makers they supply. According to the Ministry of Steel, India produced 164.89 million tonnes of crude steel in 2025, up 10.4% on 2024. Finished steel use in April and May 2026 was 8.7% higher than a year earlier.
- Wire rod mills and re-rollers without their own melt shop
- Spring wire and prestressed concrete wire and strand makers
- Wire rope and tyre bead wire manufacturers
- Forging units making hand tools and farm implements
- Steel traders supplying smaller re-rollers
What buyers pay for: a wire drawer loses money when a coil breaks on the machine. Mills therefore stay with a billet supplier whose carbon and residuals are steady from heat to heat, even at a small premium.
Mistakes that weaken a high carbon steel project report
- Assuming the furnace will clean the steel
An induction furnace removes little phosphorus or sulphur. A report that budgets cheap mixed scrap will not make saleable high carbon grades.
- Selling every heat at the high carbon price
Some heats miss the grade and are sold as ordinary billets at a discount. Yield and off-grade sales should be in the projections.
- Using the wrong power tariff
Melting is power-hungry, and HT tariffs include demand charges that vary by state. Take the tariff from your distribution company's current order.
- Skipping the ladle furnace to save cost
Without it, carbon control and inclusion levels rarely meet wire rod mill specifications, and the plant ends up selling mild steel billets.
- No time for the BIS licence
Billets need a BIS licence before sale. Leaving it out of the implementation schedule delays revenue while loan interest runs.

High Carbon Steel project report: frequently asked questions
What is the high carbon steel manufacturing plant cost in India?
An induction furnace melt shop of about 30–40 MT per day, with ladle refining and a billet caster, needs roughly ₹12–18 crore including land, building and working capital margin. Our sample report models a 33 MT per day plant at ₹1,312 lakh. These are indicative figures; adding a rolling mill or a bigger furnace raises the cost considerably.
How much carbon does high carbon steel contain?
High carbon steel usually carries about 0.6–1.0% carbon, against under 0.3% in mild steel. The Indian standard for high carbon wire rods, IS 7904, covers grades from HC 38 to HC 88, where the number roughly shows carbon in hundredths of a percent. Spring, prestressed concrete and rope wire use the upper grades.
Can an induction furnace make high carbon steel billets?
Yes, if the charge is chosen with care and a ladle refining furnace follows the furnace. An induction furnace melts well but removes very little phosphorus or sulphur, so clean scrap and sponge iron are needed. The ladle furnace then sets carbon precisely, adds ferro alloys and floats out inclusions before casting.
Is BIS certification mandatory for high carbon steel billets?
Yes. Billets and blooms for re-rolling are covered by IS 14650:2023 under the Steel Quality Control Order, and BIS set 28 September 2024 as its implementation date. If you also roll high carbon wire rods, IS 7904 applies to them. Plan the BIS licence before your first sale, since uncertified material cannot be sold.
Is a high carbon steel plant profitable?
In our illustrative sample, a 33 MT per day plant earns a 15% return on investment in Year 3. It breaks even at 47% of capacity and pays back in about 4.5 years. Margins are thinner than in finished products, so profit depends on scrap buying, power tariff, yield and the premium buyers pay for consistent chemistry.
Is the high carbon steel project report PDF free, and can I use it for a bank loan?
The sample PDF is free to view and download. It shows the format and depth of an NPCS report. Its figures are representative and not based on a real project, so it should not be submitted to a bank. For a loan, NPCS prepares a report for your own capacity, site and lender.
