JIS G4305 SUS 202 Cold Rolled Stainless Steel Coil Supplier

SUS202 Cold Rolled Stainless Steel Coil & Sheet | JIS G4305 202 Stainless Steel Strip Manufacturer & Exporter – Gangsteel

Gangsteel is a premier manufacturer and global exporter specializing in premium JIS G4305 SUS202 cold rolled stainless steel coils, sheets, and strips. As an enhanced austenitic grade in the 200 series, SUS202 (also referred to as Grade 202 or UNS S20200) builds on the cost-effective attributes of SUS201 by offering higher manganese content (7.5–10.0%) and slightly elevated nickel (4.0–6.0%), resulting in improved corrosion resistance, mechanical strength, toughness, and overall performance in moderately corrosive environments.

Our state-of-the-art cold rolling lines produce SUS202 with exceptional surface quality (2B, BA, No.4, HL, Mirror finishes), precise dimensional tolerances, and reliable properties compliant with JIS G4305 (Cold-rolled stainless steel plate, sheet and strip). Equivalent to ASTM A240/A666 Type 202 and EN 1.4373, our SUS202 products serve demanding sectors including architectural decoration, kitchenware, hotel supplies, public facilities, appliances, and general fabrication worldwide.

This comprehensive product introduction details every key aspect of Gangsteel's JIS G4305 SUS202 cold rolled stainless steel — from specifications and properties (presented in tables) to manufacturing, applications, advantages, and why we are the preferred partner for high-volume, quality-driven supply.

Introduction to SUS202 Stainless Steel

SUS202 is a chromium-nickel-manganese austenitic stainless steel designed as an upgraded alternative to SUS201. The increased manganese and nickel levels enhance austenite stability, providing better general corrosion resistance, higher tensile strength in annealed condition, and improved toughness at low temperatures compared to lower-nickel 200-series grades.

While maintaining the economic benefits of reduced nickel dependency (versus traditional 304), SUS202 delivers superior weldability, formability after annealing, and resistance to mild atmospheric and organic corrosives. It remains non-magnetic in the annealed state but develops slight magnetism upon cold working due to strain-induced martensite.

Gangsteel focuses exclusively on cold rolled SUS202, optimizing it for high-speed stamping, deep drawing, bending, polishing, and welding in consumer, decorative, and light industrial applications.

Chemical Composition of JIS G4305 SUS202

JIS G4305 defines the following composition for SUS202 (weight %):

Chemical Composition Table

Gangsteel's heats adhere to mid-range values for optimal balance of cost, formability, and performance. Full ladle analysis and EN 10204 3.1 certification are standard.

Mechanical Properties

In the annealed condition per JIS G4305, SUS202 provides:

Cold-Worked Tempers(available at Gangsteel):

• 1/4 Hard: Rm ≈ 860–1050 MPa, Rp0.2 ≈ 550 MPa, Elongation ≈ 20–30%
• 1/2 Hard: Rm ≈ 1000–1200 MPa, Rp0.2 ≈ 750–850 MPa, Elongation ≈ 10–20%
• Full Hard: Rm ≈ 1250+ MPa, high strength for reinforcements.

SUS202's moderate work-hardening rate allows tailored properties via controlled reduction.

Finishes: 2B (standard matte), BA (bright annealed), No.4/HL (brushed), Mirror/Etched. Protective films and custom slitting available.

Available Forms, Sizes, and Specifications

• Cold rolled coils: 0.3–3.0 mm thick, up to 1524 mm wide
• Cold rolled sheets: Cut-to-length up to 6000 mm
• Strips: Narrow from 10 mm

Compliant with JIS G4305; optional ASTM/EN cross-certification. Tolerances per JIS or tighter.

Key Applications of SUS202 Cold Rolled Products

SUS202 excels in mildly corrosive, cost-sensitive settings:

Architectural and Decorative

• Hotel lobby panels, elevator interiors, handrails, wall cladding
• Public facility trim, signage, shop fittings

Consumer Appliances and Kitchenware

• Sinks, cookware, utensils, refrigerator panels
• Washing machine drums, microwave components

General Fabrication and Industrial

• Food service equipment (indoor/moderate exposure)
• Hose clamps, conveyor parts, light structural supports

Its upgraded resistance suits environments where SUS201 may underperform.

Advantages of Choosing SUS202 Stainless Steel

• Enhanced corrosion resistance over SUS201 due to higher Mn/Ni/Cr
• Superior strength and toughness in annealed/cold-worked states
• Excellent formability and polishability for aesthetics
• Cost-effective nickel reduction vs. 304/316
• Good weldability with austenitic fillers (e.g., ER308)
• Reliable in indoor/mild outdoor conditions
• High recyclability and sustainability

Corrosion and Oxidation Resistance

SUS202's passive layer resists atmospheric, mild acid/organic, and humidity corrosion better than SUS201. Scaling resistance up to ~800°C intermittent; not for prolonged high-heat.

Weldability and Fabrication

TIG/MIG/resistance/laser welding compatible. Low carbon reduces sensitization; post-weld annealing optional. High ductility supports complex shapes.
