American standard A106B seamless steel tube is a widely used high-quality steel pipe, which is widely used in petroleum, chemical and boiler industries. The material has good mechanical properties. American standard A106B seamless pipe implements ASTM A106 / A106M high temperature operation carbon steel seamless steel pipe standard, grade B level. It can be seen from the pipeline standard of ASME B31.3 chemical plant and petroleum refinery: American standard A106 seamless pipe material temperature range: -28.9 ~ 565 ℃.
American standard A106B seamless steel pipe is made of American material, corresponding to China’s 20 # steel pipe. A106B chemical composition: Carbon (C): 0.17 ～ 0.24, silicon (Si): 0.17 ～ 0.37, manganese (Mn): 0.35 ～ 0.65, phosphorus (P) ≤0.030, sulfur (S): ≤0.030, Cr / Mo / V trace
Grade A106B: A106B Tensile strength MPa: 410 ～ 550 Yield point MPa: 245 Elongation (%): 24
