ASME SA-106/SA-106M GR.B seamless steel pipe is a type of seamless steel pipe material in the American ASME standard. The American standard carbon steel high-temperature operation seamless steel pipe, where Gr.B represents the grade of steel (full name: Grade B), is mainly used for the heating surface pipes of low and medium-pressure boilers (working pressure generally not exceeding 5.88 MPa, working temperature below 450°C); used for the heating surface pipes of high-pressure boilers (working pressure generally above 9.8 MPa, working temperature between 450°C to 650°C), economizers, superheaters, reheaters, and pipes for petrochemical industry, etc.

Chemical composition of ASTM A106B seamless steel pipe:

Carbon (C): 0.07-0.13

Silicon (Si): 0.07-0.37

Manganese (Mn): 0.35-0.65

Phosphorus (P): ≤0.035

Sulfur (S): ≤0.035

Nickel (Ni): ≤0.20

Chromium (Cr): ≤0.15

Copper (Cu): ≤0.250
