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.Pipe clamp - Pinyin guan gu, English coupling, it is a commonly used accessory in industrial pipeline connection. Also known as Guan Gu.Usually plumbers also call it direct during use.Purpose: Pipe clamp is a short pipe used to connect two pipes. Also called external joint. Pipe clamp is widely used in civil construction, industry, agriculture and other fields because of its convenience.According to the material classification: carbon steel, stainless steel, alloy steel, pvc, plastic, etc.Connection methods: threaded connection, welding, fusion
