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. Reducers, also known as reducers, are one of the chemical pipe fittings used to connect two pipes of different diameters. They are divided into concentric reducers and eccentric reducers. The fittings used to connect two interface pipes of different diameters or different cross-sections are reducers. Reducers are therefore also called "reducers". Reducers can be divided into circular reducers, rectangular reducers, square reducers and rectangular connecting pipes with twisting directions, which are divided according to the shape of the pipe fittings. According to the different diameters at both ends of the pipe, pipes of different diameters are divided into reduced diameters and eccentric reduced diameters. (Circular reducers and square reducers are prone to produce concentric and eccentric diameters, while rectangular reducers will only produce single-sided deflection and double-sided deflection)
