Adopting professional centerless grinding and precision finishing technology, this 316 alloy steel round bar features ultra-smooth ground surface, high dimensional accuracy, perfect straightness, outstanding corrosion resistance and stable mechanical performance. Specially engineered and widely applied for medical equipment, medical parts processing, building construction, structural engineering, machinery manufacturing and industrial precision components. 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.
