316 stainless steel, 18Cr-12Ni-2.5Mo, due to the addition of Mo, has excellent corrosion resistance, atmospheric corrosion resistance, and high-temperature strength, and can be used under harsh conditions; Good work hardening property (non-magnetic). Equipment used in seawater, chemical, dye, papermaking, oxalic acid, fertilizer and other production equipment; Photography, food industry, coastal facilities, ropes, CD poles, bolts, nuts. Chemical composition of 316 stainless steel: 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. Mechanical properties of 316 stainless steel, tensile strength (Mpa) 620 MIN, yield strength (Mpa) 310 MIN, elongation (%) 30 MIN, area reduction (%) 40 MIN, density of 316 stainless steel 8.03 g/cm3, commonly used for austenitic stainless steel.
It is divided into chromium stainless steel, chromium nickel stainless steel, and chromium manganese nitrogen stainless steel according to its main chemical composition; It can also be divided into acid resistant stainless steel and heat resistant stainless steel based on its performance characteristics; Usually classified by metallographic organization. According to the metallographic structure, it can be classified as: ferritic (F) stainless steel, martensite (M) stainless steel, austenitic (A) stainless steel, austenitic ferrite (A-F) duplex stainless steel, austenitic martensite (A-M) duplex stainless steel and precipitation hardening (PH) stainless steel.
