从China供应商批发进口431 316 631 Stock Stainless Steel Plate — FOB条款

This listing covers stock stainless steel plates in grades 431, 316, and 631, supplied by Jiangsu Steel Group Co., Ltd. from China. The plates are available in 200, 300, and 400 series, with confirmed grades including 201, 202, 301, 304, and 316. Each grade offers distinct mechanical properties: 316 provides superior corrosion resistance in chloride environments, 431 delivers high tensile strength with moderate corrosion resistance, and 631 is a precipitation-hardening grade with excellent formability and strength.

The material composition follows standard industry specifications for each grade. 316 typically contains 16-18% chromium, 10-14% nickel, and 2-3% molybdenum, which enhances its resistance to pitting and crevice corrosion. 431 is a martensitic grade with around 15-17% chromium and 1-2% nickel, offering good hardness and wear resistance. 631, also known as 17-7PH, combines 17% chromium and 7% nickel with aluminum additions for precipitation hardening. Surface finishes include 2B, BA, and #4, with thicknesses typically ranging from 0.3mm to 50mm for industrial applications.

These plates are used in construction, automotive, aerospace, and manufacturing sectors for structural components, decorative finishes, and high-stress applications. Automotive manufacturers use 431 for springs and fasteners, while 316 is preferred for chemical processing equipment and marine environments. Aerospace applications often specify 631 for parts requiring high strength-to-weight ratios. Buyers should confirm exact grade availability, thickness tolerances, and surface finish requirements with Jiangsu Steel Group Co., Ltd., as stock sizes and custom cuts vary by order.
