AISI 630 coils suppliers China
As a professional stainless steel supplier, GNEE offers premium-quality AISI 630 (17-4PH) precipitation hardened stainless steel coils, available in thicknesses from 0.3 to 6.0mm for cold-rolled coils and 3.0 to 100mm for hot-rolled coils. Thickness tolerances are tightly controlled within ±0.01–0.03mm, and widths range from 500 to 2000mm, with slitting down to 100mm supported. We provide precision cutting through laser or waterjet processing, ensuring high dimensional accuracy. All coils comply with ASTM A564, ASME SA564, and are certified by ISO 9001 and CE, with every batch accompanied by a Certificate of Analysis (COA) and SGS inspection report.
Advantages
Enhanced Mechanical and Corrosion Resistance
GNEE's AISI 630 stainless steel coils are processed with solution treatment (1040–1100°C) followed by age hardening (480–620°C), achieving tensile strengths ≥1034 MPa while maintaining excellent toughness. This strength performance significantly exceeds conventional austenitic stainless steels. In addition, AISI 630 exhibits superior corrosion resistance compared to martensitic grades, approaching the level of 304 stainless steel.
Versatile Surface Finishes for Industrial & Decorative Use
We offer various surface finishes including 2B, BA (bright annealed), brushed (hairline), and sandblasted, with surface roughness Ra ≤ 0.8μm, compliant with food-grade hygiene and decorative requirements.
Customized Hardness & Broad Applications
17-4PH stainless steel coils undergo a custom aging process to a custom hardness between 36-44 HRC, making these coils ideal for applications such as aerospace, medical devices, and chemical processing equipment requiring stringent mechanical and corrosion properties.
