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.Generally a professional term, tee is a pipe fitting, pipe connector, used at the branch pipe of the main pipeline. Equal diameter tee is a type of tee, and there are two types of tees: general equal diameter tee and reducing tee. It is named because the three ends can be connected to the pipe.Equal diameter tees are widely used in the construction and maintenance of projects in petrochemical, oil and gas, liquefied gas, fertilizer, power plant, nuclear power, shipbuilding, papermaking, pharmaceutical, food hygiene, urban construction and other industries. The pressure requirements for this kind of pipe fittings in industry are relatively high, and the maximum pressure can reach 600 kg. The water pipe pressure in life is relatively low, generally 16 kg.
