We are Riddhi Siddhi Impex, a Mumbai-based supplier and stockist of Stainless Steel 410 Sheets & Plates, established in 2002. We stock this hardenable martensitic grade to ASTM A240 / ASME SA-240 in sheets from 3.8 mm and plates in thicker gauges. As an ISO 9001, 14001, and 45001-certified company with a supply capacity of 400 to 500 tonnes monthly, we export to more than 60 countries. We issue EN 10204 Type 3.1 / 3.2 mill test certificates on request.
Stainless Steel 410 sheets and plates are flat-rolled martensitic stainless steel materials carrying 11.50 to 13.50% chromium and 0.08 to 0.15% carbon. That carbon minimum lets fabricators quench and temper finished parts to high hardness, something no austenitic or ferritic sheet offers. The grade stays magnetic in every condition, and its nickel-free chemistry keeps material costs low. These stainless steel sheets and plates in grade 410 are typically used to manufacture wear plates, kitchen utensils, petrochemical equipment, and automotive exhaust parts.
As a reliable 410 stainless steel sheet suppliers, our warehouse holds UNS S41000 flat stock sourced from reputed primary mills: cold-rolled sheet from 3.8 mm and hot-rolled plate up to 2000 mm wide. Material ships annealed, soft enough for shearing, punching, and forming before any hardening cycle, with EN 10204 Type 3.1 / 3.2 mill test certificates on request.
We provide ASTM A240 Type 410 Sheets & Plates in the annealed condition, with AMS 5504 material available for aerospace enquiries and slit widths held to ±0.1 mm.

Carbon defines this grade. ASTM A240 holds it between 0.08 and 0.15%, enough for a full hardening response, while 11.50 to 13.50% chromium maintains the passive surface.
| 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 plate and sheet inventory delivers excellent workability before heat treatment. Parts cut from the soft stock harden later by oil quenching and tempering.

As leading 410 stainless sheet suppliers, we dispatch material to 4 primary industries where hardness, wear life, and moderate corrosion resistance matter more than weldability:
Refineries line distillation columns with 410 stainless steel plates and cut tray components, baffles, and wear liners from it. The 12% chromium surface withstands hot, sulphur-bearing hydrocarbon streams that attack carbon steel, at a cost well under nickel-bearing alternatives.
Valve makers machine gates, seats, and wedge faces from Grade 410 plate, then harden the finished parts. Quenched and tempered material resists erosion from steam and throttled water, so pump wear plates and impeller shrouds come off the same stock.
Cutlery producers blank knife blades, scissors, and utensil bodies from 410 stainless steel sheet. Blanks harden after forming to take a lasting edge, and the chromium content rides out food acids and daily washing that would stain plain steel.
Engineering shops turn 410 SS sheet and plate into machine bases, fixtures, and press tooling, while automotive fabricators use them for heat shields and hardened wear strips.
Consignments leave from our Mumbai and Taloja warehouses in export-grade packing, booked for sea freight.

Stainless Steel 410 Sheets & Plates price in India is around ₹150 to ₹250 per kg, roughly $1.6 to $2.6 per kg for export buyers. The range is indicative; ferrochrome benchmarks, thickness, finish, and volume all move the final figure. Call or WhatsApp us for today's price.
The difference between SS 410 sheets and SS 410 plates is thickness. We stock sheets from 3.8 mm to 6 mm, mostly cold rolled, while plates run above 6 mm and above, hot rolled. Both fall under ASTM A240.
Yes, SS 410 plates can be hardened by heat treatment. The martensitic structure responds to oil quenching and tempering, so parts cut from annealed plate reach high hardness after fabrication.
Yes, SS 410 sheets and plates are magnetic. The martensitic structure attracts a magnet in the annealed as well as the hardened condition.
The difference between SS 410 and SS 410S sheets and plates is carbon. Type 410 holds 0.08 to 0.15% and hardens by quenching, while 410S caps carbon at 0.08%, trading hardenability for easier welding.
Yes, we provide EN 10204 Type 3.1 / 3.2 mill test certificates on request with every consignment of SS 410 sheets and plates.
