ASTM A106 Gr.B seamless steel pipe is a widely used low-carbon steel, which is widely used in petroleum, chemical, and boiler industries. This material has good mechanical properties. ASTM A106 Gr.B seamless steel pipe is equivalent to 20 steel seamless steel pipes in our country, and it is in accordance with ASTM A106/A106M high-temperature working carbon steel seamless steel pipe standard, grade B. It can be seen from the ASME standard: ASTM A106 Gr.B seamless steel pipe operating temperature range: -28.9~565℃.
According to the requirements of ASTM A106, the mechanical properties of ASTM A106 Gr.B seamless steel pipe should meet the following requirements: Mechanical properties: (tensile strength Rm415MPa, yield strength ReL240MPa, elongation 12%)
ASTM A106 Gr.B seamless steel pipe has good welding performance. Due to the low C content, it will not produce severe hardened structure due to welding under normal circumstances. After welding, ASTM A106 Gr.B seamless steel pipe has good plasticity and toughness. The welding process does not need to take special technological measures to obtain a satisfactory welded joint.
