ASTM A519 AISI 4130 alloy seamless steel pipe introduction
4130 is a chromium-molybdenum alloy steel pipe model.
Chromium-molybdenum steel alloy steel pipe is a kind of seamless steel pipe, and its performance is much higher than that of ordinary seamless steel pipe. Because this type of steel pipe contains more Cr, its high temperature, low temperature and corrosion resistance are unmatched by other seamless steel pipes. Therefore, alloy pipes are widely used in petroleum, chemical, electric power, boiler and other industries.
What kind of steel pipe is 4130?
4130 corresponds to the domestic grade 30CrMo, and the tensile strength is generally above 700MPa. The welding wire needs to use ER70-G high-strength welding wire, which can be asked when purchasing.
