1.302 The corresponding Chinese grade is 1cr18ni9.
2.Characteristics and uses: the cold processing has high strength, but the elongation rate is slightly worse than 1cr17ni7.
Stainless Steel tube: OD 6-377mm, wall thickness 1.0-20mm (seamless).
Welded pipe od 10-1210mm wall thickness 0.5-10mm. (Note: Non-standard specifications customized, length can be fixed-scale)
302 Steel Pipe Classification：
Stainless steel pipe According to production methods are divided into seamless pipe and welded pipe two categories, seamless steel tube can be divided into hot-rolled pipe, cold-rolled pipe, cold drawn pipe and extruded pipe, cold drawn, rolled steel pipe two times processing; welded pipe is divided into straight seam welded pipe and spiral welded pipe. Resistant to air, steam, water and other weak corrosive media and acid, alkali, salt and other chemical etching medium corrosion of steel, also known as stainless acid-resistant steel.
302 Steel Pipe characteristics:
Stainless steel tube has three kinds of characteristics: weldability, corrosion resistance, polishing performance. Stainless steel pipe can be divided into Cr-ni (300 series), Cr-mn-ni (200 series), Precipitation hardening System (600 series), high temperature and corrosion resistance Ni-based alloy and Hastelloy, etc.
Widely used in consumer goods, food and medical care, construction and decoration, automotive and transportation, environment and energy. such as: 201, 202/301 304, 304L, 304j1, 309s-310s, 316, 316L, 321/409, 410, 420, 430, 443, 444/904l, 45#, and 2205 duplex stainless steel.
