Main Materials & Common Standards of Alloy Steel Pipes

The performance of alloy steel pipe is much higher than that of general seamless steel pipe, because there are more Cr in alloy steel pipe. And its performance such as high temperature resistance, low temperature resistance and corrosion resistance are inferior to those of other seamless steel pipes. So alloy steel pipe is widely used in petroleum industry, chemical industry, electric power industry, boiler and other industries.
 

Alloy steel pipes are mainly divided as the following materials:
16Mn/40Mn2 alloy steel pipe, 45Mn2 alloy steel pipe, 27SiMn alloy steel pipe, 20Cr alloy steel pipe, 40Cr alloy steel pipe, 20CrMo alloy steel pipe, 35CrMo alloy steel pipe, 38CrMoAl alloy steel pipe, 50CrV alloy steel pipe, 30CrMnSi alloy steel pipe, 335P11 alloy steel pipe, P91 alloy steel pipe, P92 alloy steel pipe, 15CrMoG alloy steel pipe, 12Cr1MoVG alloy steel pipe, 1Cr5Mo alloy steel pipe.

Metal steel pipe, Cr5Mo alloy steel pipe, Cr9Mo alloy steel pipe, 30Cr9Mo alloy steel pipe, 15CrMo alloy steel pipe, 35CrMo alloy steel pipe, 12Cr1MoV alloy steel pipe, 10CrMo910 alloy steel pipe, A335P91 alloy steel pipe, 1Cr2Mo alloy steel pipe, 15MnV alloy steel pipe, 37Mn5 alloy steel pipe, 10Cr9Mo1VNb Alloy steel pipe, 15NiCuMoNb5 alloy steel pipe, 12Cr2MoWVTiB alloy steel pipe, WB36 alloy steel pipe, SA106B alloy steel pipe, ST45.8-III, etc.
