We are Riddhi Siddhi Impex, a Mumbai-based supplier and stockist of Stainless Steel 301 Sheets & Plates, established in 2002. We hold ready stock of austenitic flat products to ASTM A240 / ASME SA-240 from 3.8 mm upward. Our ISO 9001, 14001, and 45001-certified company holds a 400 to 500-tonne monthly supply capacity and ships with EN 10204 Type 3.1 / 3.2 certificates on request.
Stainless Steel 301 sheets and plates are flat-rolled austenitic stainless steel, leaner in nickel than Type 304, with 16 to 18% chromium and 6 to 8% nickel. The lean nickel keeps the austenite metastable, so these Stainless Steel Sheets and Plates work-harden strongly under cold work. The supplied annealed AISI 301 sheet still draws and bends cleanly. Stainless Steel 301 Sheets & Plates are typically used in aircraft structural components, railcars, trailers, conveyor belts, and automotive trim.
As one of the reliable 301 stainless steel sheet suppliers, we stock this flat product rather than roll the base metal, sourcing from reputed primary mills and slitting sheet to width in-house. Cold-rolled sheet ships in 2B, BA, Scotch-Brite, and Matte finishes; hot-rolled plate arrives No.1 pickled. Every ASTM A240 Type 301 sheet supplied is annealed, with mill or slit edges and test papers on request.
We provide ASTM A240 Type 301 sheets and plates in the annealed condition, in cold-rolled and hot-rolled forms, from 3.8 mm thick and up to 2000 mm wide.

Nickel defines this grade. At 6 to 8% it sits below the 8 to 10.5% of Type 304, which leaves the austenite metastable and drives 301's work-hardening. Chromium at 16 to 18% builds the passive film behind its corrosion resistance.

These 4 industries specify most of the Stainless Steel 301 sheets and plates we supply, choosing the grade for work-hardening strength, annealed formability, or a bright surface over corrosion resistance.
Automotive fabricators press 301 SS sheet into structural brackets, body reinforcements, wheel covers, and trim. The high work-hardening rate forms a thin sheet into a stiff, light part, while annealed stock deep-draws without splitting.
Aircraft builders specify Alloy 301 sheet for structural panelling, floor sections, and reinforcing members where strength-to-weight counts. The grade forms complex shapes annealed, then hardens under cold work, so panels stay light yet rigid.
Architectural fabricators use 301 sheets and plates for cladding, curtain-wall members, and structural trim. Cold forming adds stiffness, while the bright 2B and BA surfaces we stock weather outdoors, so slim panels hold their line.
Catering-equipment makers form 301 stainless steel sheet into worktops, splashbacks, conveyor parts, and utensil bodies. The annealed sheet takes a hygienic finish and work-hardens at wear points, so surfaces resist dents through repeated wash cycles.
Orders are issued from our Mumbai and Taloja warehouses in wooden cases or on pallets, papers included.

Stainless Steel 301 Sheets & Plates price in India is around ₹200 to ₹350 per kg, or roughly $2.10 to $3.70 per kg for international buyers. The rate tracks nickel and ferrochrome benchmarks, while thickness, finish, and gauge move the figure. Volume discounts apply, so call or WhatsApp us for today's rate.
The price of SS 301 sheets and plates per kg runs around ₹200 to ₹350 in India, or $2.10 to $3.70 for export orders. Thickness, finish, and quantity move the figure, so send your requirement for a firm quote.
For sheets, SS 301 work-hardens to higher strength than SS 304 and suits structural and spring parts. SS 304 holds broader corrosion resistance from its 8 to 10.5% nickel. Pick by which property leads your application.
Cold-rolled SS 301 sheets come in 2B, BA, Scotch-Brite, and Matte, while hot-rolled plates ship No.1 pickled.
Yes, SS 301 sheets weld cleanly using standard austenitic methods with a matching filler. Because the grade carries up to 0.15% carbon, a post-weld anneal restores full corrosion resistance.
Standard lead time for SS 301 sheets and plates is 4 to 5 days from ready stock, with urgent dispatch in 2 to 3 days. Contact us to confirm availability for your size and finish.
You can source SS 301 sheets and plates in India from us at Riddhi Siddhi Impex. Our Mumbai warehouse holds Type 301 flat product for immediate dispatch. As a supplier, stockist, and exporter, we serve buyers across India and overseas. Phone or WhatsApp us; quotes will be provided within 24 hours.
