Lead Paragraph

Our 201 cold rolled stainless steel coil combines superior corrosion resistance with a high-quality 2B mill finish for demanding decorative and structural applications. Manufactured to ASTM A240 / JIS G4305 standards, this austenitic grade offers excellent formability and weldability. Available in thicknesses from 0.3mm to 3.0mm and widths up to 1250mm, with precision slitting and surface protection options. Ideal for cost-effective solutions in kitchenware, architectural panels, and light industrial components.

Product Overview & Performance

• Grade 201 stainless steel is a chromium-manganese-nickel austenitic alloy designed as an economical substitute for 304 in non-critical environments. Our 201 CR coil features:

• Corrosion Resistance: Sufficient for indoor use, including exposure to water, mild chemicals, and food residue. Passes 5% neutral salt spray test (>72 hours).

• Mechanical Strength: Yield strength ≥260 MPa, tensile strength ≥520 MPa – higher than 304 for thinner gauge designs.

• 2B Surface Excellence: Smooth, reflective finish (Ra ≤0.4μm) achieved through controlled cold rolling and bright annealing. Suitable for post-fabrication brushing, polishing, or coating.

• Precision Processing: Thickness tolerance ±0.02mm (for coils ≤1.5mm), width tolerance ±0.5mm, enabling automated press feeding and laser cutting.

Frequently Asked Questions

Q: How does 201 stainless steel compare to 304 in corrosion resistance?

A: 201 has lower nickel content (3.5-5.5%) than 304 (8-10.5%), making it less resistant in highly aggressive environments such as salt spray or strong acids. However, for indoor use in kitchens, retail displays, and appliances, its corrosion resistance is sufficient and offers significant cost savings (typically 30-40% lower price).

Q: Can 201 cold rolled coil be welded without losing corrosion resistance?

A: Yes, 201 exhibits good weldability using TIG or MIG processes (ER308L filler recommended). Post-welding, passivation is advised to restore the protective chromium oxide layer. Weld zone corrosion resistance is adequate for non-submerged indoor applications.

Q: What is the minimum order quantity (MOQ) for 201 CR stainless steel coil?

A: Standard MOQ for slitted coil is 3 tons per specification. For full width master coil (1219mm/1250mm), MOQ is 5 tons. We also support LCL trial orders (1-2 tons) for first-time buyers.

Q: Do you offer cut-to-length sheets from 201 coil?

A: Yes, we provide custom cut-to-length sheets (length: 1000-4000mm) with deburred edges. Please specify your sheet dimensions for quotation.
