Factory direct supply, full specification stock, strict quality inspection and full certification support.

316 is a classic molybdenum-containing austenitic stainless steel alloy with main chemical composition: Cr 16.00-18.00%, Ni 10.00-14.00%, Mo 2.00-3.00%, Carbon ≤0.08%. Low carbon content ensures excellent intergranular corrosion resistance. Molybdenum element greatly enhances resistance to chloride, salt spray, seawater and weak acid corrosion. Stable alloy structure, non-magnetic, uniform internal metallographic organization, no impurities and internal cracks.
