What are the materials of alloy steel pipe

　　Alloy steel pipe seamless steel pipe features much higher than usual, because the pipe inside containing Cr more, the high temperature resistant, low temperature resistant, corrosion-resistant function other than seamless steel pipe, alloy pipe, so in petroleum, chemical, electric power, boiler etc. occupation useful than the quasi widely.Alloy pipe main raw material 16mn/40Mn2 alloy steel, 45Mn2 alloy steel, 27SiMn alloy steel, 20Cr alloy steel, 40Cr alloy steel, 20CrMo alloy steel, 35crMo alloy steel, 38CrMoAl alloy steel, 50CrV alloy steel, 30CrMnSi alloy steel, 335P11 alloy steel pipe, steel pipe, alloy steel pipe of P92 P91 alloy, 15CrMoG alloy steel pipe, 12Cr1MoVG alloy 1Cr5Mo alloy steel pipe, steel pipe, alloy steel pipe, steel pipe of Cr5Mo Cr9Mo alloy, 0Cr9Mo alloy steel pipe, steel pipe, alloy steel pipe of 35CrMo 15CrMo alloy, 12Cr1MoV alloy steel pipe, 10CrMo910 alloy steel pipe, alloy steel pipe, steel pipe of A335P91 1Cr2Mo alloy, 15MnV alloy steel pipe, steel pipe, alloy steel pipe of 10Cr9Mo1VNb 37Mn5 alloy, 15NiCuMoNb5 alloy steel pipe, alloy steel pipe, WB36 12Cr2MoWVTiB alloy steel pipe, alloy steel pipe, SA106B ST45.8-III; carbon high-pressure boiler tubes of GB5310-95 raw material: the above 20G alloy steel pipe, alloy steel pipe, 20MG 25MG alloy steel, 15MoG alloy steel, 20MoG alloy steel is commonly used materials,
