316 stainless steel, 18Cr-12Ni-2.5Mo Due to the addition of Mo, its corrosion resistance, atmospheric corrosion resistance and high temperature strength are particularly good, and it can be used under harsh conditions; excellent work hardening (non-magnetic). Equipment used in seawater, chemical, dye, papermaking, oxalic acid, fertilizer and other production equipment; photography, food industry, coastal facilities, ropes, CD rods, 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, this value is generally used for austenitic stainless steel.
The butt-weld flange is a kind of pipe fitting, which refers to a flange with a neck and a round tube transition and is connected to the pipe by butt welding. The butt-weld flange is not easy to deform, has good sealing, is widely used, has corresponding rigidity and elasticity requirements and reasonable butt welding thinning transition, the distance between the weld and the joint surface is large, and the joint surface is free from welding temperature deformation.The butt-weld flange is a kind of pipe fitting, which refers to a flange with a neck and a round tube transition and is connected to the pipe by butt welding.
