Stainless Steel 316 has slightly better corrosion resistance than 302 and 304. It also has better non-magnetic properties.
316 stainless steel, 18cr-12ni-2.5 Mo due to the addition of Mo, so its corrosion resistance, atmospheric corrosion resistance and high temperature strength is particularly good, can be used in caustic conditions.
Excellent work hardening (non magnetic).Seawater equipment, chemical, dye, paper, oxalic acid, fertilizer and other production equipment;Photography, food industry, coastal facilities, ropes, CD poles, bolts, nuts.
Stainless Steel 316 is also known as AISI 316.
