What is the ASTM A671 grade?
ASTM A671 is a standard specification for the manufacture of high-pressure, high-temperature pipes and pipes for all types and grades of carbon steel, low alloy steel, stainless steel and high alloy steel pipe.

A671 CA55 steel pipe is a low alloy steel pipe widely used in high temperature and high pressure environments. Its excellent mechanical properties make it widely used in many industrial fields. It is mainly used to manufacture pipes and containers in high-pressure and high-temperature environments, such as petrochemical, chemical processing and power industries.
Tensile strength: ≥585MPa, it can withstand large tensile force without breaking. Yield strength: ≥415MPa, indicating that it can withstand large compression or shear stress without yielding deformation. Elongation: ≥17% Elongation refers to the ratio of the maximum deformation that can occur to the original length of a steel pipe when it is subjected to tensile load. It shows that it has good plastic deformation ability and can withstand large tensile deformation without breaking. Shrinkage: ≥35%, indicating that it has good dimensional stability during heating and cooling. Impact energy: ≥34J Impact energy refers to the ability of the steel pipe to resist impact load during the impact test. Hardness: ≤187HB Hardness refers to the hardness and wear resistance of the steel pipe surface. The low hardness of A671 CA55 welded steel pipe indicates that it has strong surface hardness and wear resistance and can withstand greater friction and wear.

ASTMA671 CA55 corresponds to material grade A285GR.C
Chemical composition: carbon ≤ 0.28%, manganese ≤ 0.98%, phosphorus ≤ 0.035%, sulfur ≤ 0.035%
