We are Riddhi Siddhi Impex, one of the most trusted 430 stainless steel strip manufacturers and suppliers working from Mumbai since 2002. We offer ferritic chromium lines meeting ASTM A240/ASME SA-240 requirements, with thicknesses from 0.03 to 5 mm. We maintain ready stock and EN 10204 Type 3.1 / 3.2 certificates as an ISO 9001, 14001, and 45001-certified company with 400-500-tonne monthly supply capacity.
Stainless Steel 430 strips are narrow, precision-slit ferritic chromium strip supplied in coil form which is designated as UNS S43000. Chromium content ranges from 16.0% to 18.0%, with nickel held to a residual 0.75% maximum, so the alloy costs less than austenitic grades and remains less affected by fluctuations in nickel prices. The strip is magnetic in every condition, resists oxidation in continuous service up to 815 °C, and forms cleanly on standard tooling. Heat treatment can't harden it. SS 430 strips offer cost-effective formability and corrosion resistance for automotive, appliance, architectural, and various industrial applications.
Every strip we sell is processed on our own Mumbai lines into high-precision SS 430 Slitting Coil forms rather than traded at mill width. Type 430 anchors the ferritic end of our stainless steel strips range. Buyers choose any width between 3 mm and 2000 mm, in annealed (soft) condition, with BA, 2B, Scotch-Brite, Matte, or HR pickled surfaces. Documented traceability follows each coil from source stock to dispatch.
We provide ASTM A240 Type 430 strip in annealed condition, cold rolled or hot rolled and pickled, precision slit to your width and dispatched in coil form from Mumbai.

Chromium does the protective work in this grade. At 16.0-18.0%, it builds the passive film that lets SS 430 strips withstand mild atmospheres, fresh water, and many food acids. Full ASME SA-240 limits appear below.

| Manganese (Mn) | 1.00 max |
| Phosphorus (P) | 0.040 max |

Annealed Stainless Steel 430 Winding Strip reaches a 450 MPa minimum tensile strength while remaining highly workable for deep drawing, bending, and roll forming. We supply this grade exclusively in a soft, fully annealed condition. Surface finishes like 2B receive a standard, light skin-pass (temper roll) to ensure maximum flatnes

As a trusted 430 stainless steel strip supplier, we provide precision-slit coils to these 4 major industries. Each grade is chosen for formability and corrosion resistance at a cost nickel-bearing austenitic grades cannot afford.
Automotive trim shops press 430 stainless steel strip into window mouldings, door garnish, and bright interior accents. The grade polishes well and keeps its shine in normal road atmospheres. For exterior parts facing heavy de-icing salt, we recommend 304 instead.
Appliance plants form washing machine panels, dishwasher linings, refrigerator trims, and oven side walls from this grade. Utensil makers draw it into bowls, cutlery blanks and sink accessories. A BA finish leaves visible surfaces showroom-ready without a polishing step.
Interior cladding, lift panels, column covers, and decorative screens use SS 430 strip where a bright, uniform stainless surface must fit a tight budget. Indoor and sheltered installations suit the grade best; coastal facades call for higher alloys.
Hose clamps, banding, chimney liners, burner parts, and hot water system components all run on ferritic Grade 430 strips. Oxidation resistance covers flue and burner duty. The magnetic structure suits solenoid housings, and our ±0.1 mm slit widths feed automated clamp lines without jams.
Coils leave our Mumbai and Taloja warehouses packed for sea freight, with documents matched to your incoterm.

Stainless Steel 430 Strips price range in India is around ₹175-₹255 per kg. Export orders generally land at $2-$3/kg. Ferrochrome rates shift the figure month to month, and thickness, width, finish, and quantity set the final rate. Contact us for a current quotation.
SS 430 strips are available from 0.03 mm to 5 mm thick and in any width from 3 mm to 2000 mm, slit to ±0.1 mm. Coil inner diameters run 150 mm to 610 mm, with outer diameters up to 1800 mm.
430 stainless steel strip compares to 304 strip as the lower-cost ferritic option. It holds 16.0-18.0% chromium with no deliberate nickel against 18-20% chromium and 8-10.5% nickel in 304, so it is magnetic and affordable, while 304 resists chlorides better.
Yes, SS 430 strip is magnetic in all conditions. Its ferritic structure responds to a magnet, unlike austenitic grades such as 304 and 316, which stay non-magnetic in the annealed state.
430 stainless steel strip is available in BA (Bright Annealed), 2B, No.1 (HR Pickled), No.4 (Scotch-Brite), Matte and Matte PVC finishes. BA is the most commonly specified finish for visible appliance panels.
The lead time for SS 430 strip orders is 4 to 5 days from ready stock, custom-slit widths included. Urgent requirements dispatch in 2 to 3 days.
