JIS G4305 SUS 316 Cold Rolled Stainless Steel Coil Supplier

SUS316 Cold Rolled Stainless Steel Coil & Sheet | JIS G4305 316 Stainless Steel Strip Manufacturer & Exporter – Gangsteel

Gangsteel is a leading manufacturer and global exporter of premium JIS G4305 SUS316 cold rolled stainless steel coils, sheets, and strips. As a molybdenum-bearing austenitic grade (Grade 316 or UNS S31600), SUS316 provides superior corrosion resistance, particularly in chloride-containing environments, pitting and crevice corrosion resistance, and excellent high-temperature strength compared to standard SUS304. The addition of 2-3% molybdenum significantly enhances its performance in marine, chemical, and aggressive industrial applications.

Our precision cold rolling facilities produce SUS316 with high-quality surface finishes (2B, BA, No.4, HL, Mirror), 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 316, EN 1.4401 (X5CrNiMo17-12-2), and GB 0Cr17Ni12Mo2, Gangsteel's SUS316 products serve demanding sectors worldwide including chemical processing, marine equipment, pharmaceuticals, food processing, heat exchangers, and architectural applications requiring enhanced durability.

This comprehensive product introduction details every aspect of our JIS G4305 SUS316 cold rolled stainless steel — from composition and properties (in tables) to manufacturing, applications, advantages, and why Gangsteel is your trusted partner for reliable, high-performance supply.

Introduction to SUS316 Stainless Steel

SUS316 is an enhanced 18/10/2 chromium-nickel-molybdenum austenitic stainless steel, offering better resistance to pitting and crevice corrosion than SUS304 due to molybdenum. It excels in chloride-rich environments (e.g., seawater, brackish water, chlorides) while maintaining excellent general corrosion resistance, weldability, formability, and mechanical properties across a wide temperature range.

Non-magnetic in the annealed state, SUS316 provides good toughness at cryogenic temperatures and oxidation resistance up to ~870°C intermittent. Gangsteel specializes in cold rolled SUS316, optimizing it for deep drawing, stamping, bending, polishing, and welding in corrosive service.

Key Applications of SUS316 Cold Rolled Products

SUS316 excels in corrosive, chloride-exposed environments:

Chemical and Petrochemical

• Tanks, piping, heat exchangers, valves
• Acid/chloride processing equipment

Marine and Offshore

• Boat fittings, desalination plants, coastal architecture
• Seawater handling

Food, Beverage, and Pharmaceuticals

• Processing equipment, dairy lines, sterile vessels
• Hygienic welded structures

Architectural and Industrial

• Cladding in marine atmospheres, railings
• Heat exchangers, condensers

Its pitting resistance suits aggressive conditions.

Advantages of Choosing SUS316 Stainless Steel

• Excellent pitting and crevice corrosion resistance (PREN ~24–26)
• Superior performance in chlorides vs. SUS304
• Good weldability and formability
• High-temperature strength and oxidation resistance
• Hygienic, easy-to-clean for food/pharma
• Non-magnetic annealed; recyclable
• Versatile for marine/chemical service

Corrosion and Oxidation Resistance

Superior passive layer due to Mo; resists pitting in chlorides, acids, and marine atmospheres. Oxidation resistance up to ~870°C intermittent; better than SUS304 in hot corrosives.

Weldability and Fabrication

Excellent weldability with TIG/MIG/resistance; low carbon minimizes sensitization. Use ER316/316L fillers. High ductility supports complex forming.
