316 stainless steel, 18Cr-12Ni-2.5Mo by adding Mo, so the corrosion resistance, resistance to atmospheric corrosion and high temperature strength are particularly good, in the harshness of the conditions; hardening excellent (non magnetic). Sea water equipment, chemicals, dyes, paper, oxalic acid, fertilizers and other production equipment; photography, food industry, coastal facilities, rope, CD rod, bolts, nuts. 316 stainless steel chemical composition: C ≤ 0.08, Si ≤ 1.00, Mn ≤ 2.00, P ≤ 0.035, S ≤ 0.03, Ni :10.0-14 .0, Cr :16.0-18 .5, Mo :2.0-3 .0. 316 stainless steel mechanical properties, tensile Strength (Mpa) 620 MIN, yield strength (Mpa) 310 MIN, elongation (%) 30 MIN, area reduction (%) 40 MIN, 316 stainless steel density of 8.03 g/cm3, austenitic stainless steel is generally used this value
