ASTM A106 Gr.B Steel Pipe

The material has good mechanical properties.A106-B steel pipe is equivalent to China's 20-steel no-frills steel pipe, the implementation of ASTM A106/A106M high-temperature operation of carbon steel seamless steel pipe standards, level B. The material has good mechanical properties.
According to the requirements of ASTM A106 standard, the mechanical properties of Grade B hot rolled seamless steel pipe shall meet the following requirements:Mechanical properties: (tensile strength Rm2415MPa, yield strength ReL2240MPa, elongation 212%)@ ASTM A106Gr.B Seamless Steel Pipe has very good weldability, due to the low content of C, usually does not produce serious hardening due to welding Organization, good plasticity and toughness of the joints after welding, the entire welding process does not have to take special technological measures to obtain satisfactory welded joints.

Purchase Alert.
Interestingly, many steel pipe factories have chosen to produce ASTM steel pipe with similar GB bad material, for example, many factories have produced both GB 8163 20 steel pipe and ASTM A106B steel pipe with 20 steel bad material. Do not know, many GB steel pipe and ASTM steel pipe varieties are only similar, not equivalent, although their important control indicators such as chemical composition and mechanical properties have a large overlap area, but its extended use of the provisions are not the same. Still take 20 steel pipe as an example, GB 50316 GB 8163 20 steel pipe minimum operating temperature of -19C, while ASME B313 A106B steel pipe can be used to .29% C, the purpose of the conditions of the impact test is exempted. This raise different although there is a design specification of the provisions of the difference, but the underlying reason is the Mr content of the different levels of control. Manufacturers can be unaware of these extensions, but purchasers should be aware of such differences and pass on the information and requirements to the manufacturer, otherwise this may create problems of use.
