317l austenitic stainless steel

317L austenitic stainless steel from Hongchao Stainless Steel Inc. is a molybdenum-bearing grade with UNS S31703 designation, designed for superior resistance to pitting and crevice corrosion in chloride-rich environments. The low carbon content (0.03% max) minimises carbide precipitation during welding, preserving structural integrity in fabricated components. Supplied from Dongguan, Guangdong, this alloy retains mechanical strength at elevated temperatures, making it a reliable choice for high-stress industrial applications.

The material typically contains 18-20% chromium and 11-15% nickel, with 3-4% molybdenum to enhance corrosion resistance in aggressive media. Standard forms include hot-rolled and cold-rolled sheets, plates, and coils, with surface finishes ranging from 2B to No. 1. Industry-standard tensile strength for 317L is 580 MPa minimum, with yield strength of 240 MPa, values that ensure durability in chemical processing, marine, and oil and gas sectors.

Common applications include pressure vessels, heat exchangers, and piping systems in pharmaceutical and food processing plants, where resistance to sulfuric and acetic acids is critical. Buyers typically source this grade in bulk for projects requiring long-term exposure to corrosive environments. Trade terms such as FOB or CIF are common, with packaging in wooden crates or bundles to prevent damage during transit.
