Standard specification for electric - resistance - welded low - carbon steel pipe for the chemical industry 化学工业用电阻焊低碳钢管的标准规范
Standard specification for seamless cold - drawn low - carbon steel heat - exchanger and condenser tubes 热交换器和冷凝器用无缝冷拉低碳钢管标准规范
Usage : it is suitable for welding work on materials of low - carbon steel , stainless steel , copper aluminium metals etc 用途:适用于低碳钢、不锈钢、铜、铝等多种金属材料的点焊。
When possible , the fixture should be built from low - carbon steel and large masses of steel should be normalized to minimize residual magnetism 如果可能,工装应用低碳钢制作,大块的钢板应规格化以最小化剩余的磁性
