We are Riddhi Siddhi Impex, a Mumbai-based supplier and stockist of Stainless Steel 410 Coils, established in 2002. We stock martensitic chromium coils to ASTM A240 / ASME SA-240 from 0.03 mm to 5 mm thick, with custom-slit widths to ±0.1 mm tolerance. Our ISO 9001, 14001, and 45001 certified company has a supply capacity of 400 to 500 tons monthly and exports to 60+ countries, with EN 10204 Type 3.1 / 3.2 mill test certificates on request.
Stainless Steel 410 coils are flat-rolled martensitic stainless steel holding 11.50 to 13.50% chromium with 0.08 to 0.15% carbon. The relatively higher carbon content distinguishes Grade 410 from ferritic stainless steels. The grade hardens by quenching and tempering, trading some corrosion resistance for strength and wear life. It stays magnetic in every condition and, with no nickel requirement, costs less than most stainless grades. These coils are typically used for high-strength, wear-resistant parts like fasteners, valves, and cutlery.
As a reliable 410 stainless steel coil supplier, our warehouse carries these coils as ready stock, sourced from reputed primary mills and slit to width in-house. Material ships annealed, soft enough for blanking and forming ahead of any hardening cycle, with test documentation on request.
We provide ASTM A240 Type 410 Coils in the annealed condition, hot rolled or cold rolled, custom-slit from ready stock to ±0.1 mm.

Chromium at 11.50 to 13.50% gives these stainless steel coils their passive, corrosion-resistant surface. Carbon is equally important. ASTM A240 sets a 0.08% minimum, which enables the grade to be hardened by heat treatment.
| Element | Composition (% by weight) |
|---|---|
| Carbon (C) | 0.08 to 0.15 |
| Manganese (Mn) | 1.00 max |
| Phosphorus (P) | 0.040 max |
| Sulphur (S) | 0.030 max |
| Silicon (Si) | 1.00 max |
| Chromium (Cr) | 11.50 to 13.50 |
| Nickel (Ni) | 0.75 max |
| Iron (Fe) | Balance |
Annealed 410 Stainless Steel Coils reach a minimum tensile strength of 450 MPa with 20% elongation. Fabricators typically blank and form the material in the annealed condition before heat treatment, then oil-quench and temper finished parts to roughly 40 HRC.

These 6 industries use most of the SS 410 coils we supply. Buyers select the grade for hardenability, wear resistance, and moderate corrosion protection at low cost. The following are some examples of applications of 410 stainless steel coil.
Automotive plants blank 410 SS Coils into brake components, clutch parts, and stamped brackets. The feedstock forms easily in the annealed state, then heat treats to the hardness those wear parts demand, keeping material spend low.
Cutlery makers stamp knife blanks, scissors, and utensils from SS 410 Coils. The blanks harden after forming to take and hold a working edge, and the 12% chromium surface stands up to food acids and repeated washing.
Valve builders blank seats, plates, and wear rings from 410 coil stock. Hardened parts resist erosion from steam, water, and mildly corrosive process flows, so the grade suits trim that sees constant throttling.
Refineries fit 410 stainless steel internals in distillation columns, including tray valves and caps. The grade handles hot, sulphur-bearing hydrocarbon streams where carbon steel corrodes quickly, and austenitic grades cost too much.
Fastener plants roll and blank screws, washers, and spring clips from 410 SS Coils. Parts gain final strength in the quench-and-temper cycle, giving hardware that carries load and shrugs off atmospheric rust.
Engineering shops press 410 coils into machine parts, wear strips, and tooling components. The grade forms without fuss when annealed, and its heat-treat response lets one stock material cover jobs needing varied hardness levels.

410 stainless steel coil price in India is around ₹140 to ₹240 per kg. For international buyers, it is roughly US $1.50 to $2.50 per kg, depending on specification and order quantity. The rate tracks ferrochrome benchmarks, and thickness, width, finish, and volume all move the figure, so call or WhatsApp us for today's rate.
We supply Stainless Steel 410 Coils in thicknesses from 0.03 mm to 5 mm and widths up to 2000 mm, with coil ID from 150 mm to 610 mm and OD up to 1800 mm. Custom widths are slit at ±0.1 mm.
Yes, Stainless Steel 410 Coils can be hardened by heat treatment. The martensitic structure responds to oil quenching and tempering, taking finished parts to roughly 40 HRC; we supply the coils annealed so they form easily first.
Yes, Stainless Steel 410 Coils are magnetic. The grade is ferromagnetic in both the annealed condition (ferrite plus carbides) and the hardened condition (martensite).
The main difference between SS 410 Coils and SS 430 Coils is heat-treat response. SS 410 is martensitic and hardens by quenching, while SS 430 is ferritic, carries higher chromium, and cannot be hardened that way.
Yes, we provide mill test certificates for SS 410 Coils. EN 10204 Type 3.1 / 3.2 mill test certificates are issued on request with every order.
You can source Stainless Steel 410 Coils in India from us at Riddhi Siddhi Impex. Our Mumbai warehouse holds 410 coil stock for immediate dispatch, and we serve buyers across India and overseas as a supplier, stockist, and exporter. Phone or WhatsApp us, and we will provide quotes within 24 hours.
