JIS G4305 SUS 410 Cold Rolled Stainless Steel Coil Supplier

SUS410 Cold Rolled Stainless Steel Coil & Sheet | JIS G4305 410 Stainless Steel Strip Manufacturer & Exporter – Gangsteel

Gangsteel is a leading manufacturer and global exporter of premium JIS G4305 SUS410 cold rolled stainless steel coils, sheets, and strips. As a general-purpose martensitic grade (Grade 410 or UNS S41000), SUS410 offers good corrosion resistance, high strength and hardness after heat treatment, moderate oxidation resistance up to 650–700°C (1200–1300°F), and excellent wear resistance. With 11.5–13.5% chromium and controlled carbon (≤0.15%), it is the most widely used hardenable stainless steel, providing a cost-effective balance of properties for applications requiring higher strength than austenitic grades while maintaining basic corrosion protection.

Our precision cold rolling facilities produce SUS410 with superior surface finishes (2B, BA, No.4, HL), tight tolerances (±0.02 mm), and consistent properties fully compliant with JIS G4305 (Cold-rolled stainless steel plate, sheet and strip). Equivalent to ASTM A240 Type 410, EN 1.4006 (X12Cr13), and GB 10Cr13 or 1Cr13, Gangsteel's SUS410 products serve industries worldwide including cutlery, machine parts, valves, pump shafts, turbine blades, petrochemical equipment, and automotive components.

This comprehensive product introduction details every aspect of our JIS G4305 SUS410 cold rolled stainless steel — from composition and properties (in tables) to manufacturing, applications, advantages, and why Gangsteel is your trusted partner for reliable, hardenable stainless supply.

Introduction to SUS410 Stainless Steel

SUS410 is a martensitic chromium stainless steel that can be hardened by heat treatment (quenching and tempering) to achieve high tensile strength (up to 1500+ MPa), excellent wear resistance, and moderate corrosion resistance in mild environments. It is magnetic in all conditions and provides good machinability in the annealed state. While not as corrosion-resistant as austenitic grades like SUS304 or SUS316, SUS410 performs well in fresh water, steam, mild acids, and atmospheres with low chloride exposure.

Gangsteel specializes in cold rolled SUS410, delivering material in annealed condition suitable for further heat treatment or light forming, with options for hardened/tempered properties upon customer request.

Chemical Composition of JIS G4305 SUS410

Chemical Composition Table

Gangsteel's production adheres to tight mid-range values for optimal hardenability and corrosion balance. Full chemical analysis and EN 10204 3.1 certificates are standard.

Mechanical Properties

In annealed condition per JIS G4305:

Mechanical Properties Table (Annealed)

Hardened and Tempered(typical after heat treatment):

• Quenched and tempered at 200–370°C: Rm 1105–1515 MPa, Rp0.2 1000+ MPa, Hardness 38–47 HRC
• Tempered at higher temperatures: Lower strength but improved toughness

SUS410's martensitic structure allows significant hardening via heat treatment.

Key Applications of SUS410 Cold Rolled Products

SUS410 excels in applications requiring hardness, wear resistance, and moderate corrosion protection:

Cutlery and Tools

• Knife blades, scissors, surgical instruments
• Wear-resistant components

Machine and Valve Parts

• Pump shafts, valve stems, gears
• Petrochemical gate valves

Automotive and Aerospace

• Turbine blades, fasteners
• Exhaust components

Other Uses

• Mining machinery, distillation trays
• Cryogenic structures (with toughness)

Its hardenability suits high-wear, moderate-corrosion environments.

Advantages of Choosing SUS410 Stainless Steel

• Hardenable to high strength/hardness via heat treatment
• Good corrosion resistance in mild environments (better than carbon steel)
• Excellent wear and abrasion resistance
• Moderate high-temperature oxidation (up to 650–700°C)
• Cost-effective martensitic option vs. austenitics
• Magnetic; good machinability annealed
• Versatile for cutlery, valves, and tools

Corrosion and Oxidation Resistance

Moderate resistance to atmospheric corrosion, fresh water, steam, and mild acids; lower in chlorides/acids than austenitics. Oxidation resistance up to ~700°C continuous; good in hot corrosion environments.

Weldability and Fabrication

Fair weldability; pre-heat/post-weld heat treatment recommended to avoid cracking. Use matching fillers (ER410). Annealed state allows good forming/machining; hardening post-fabrication.
