日标方矩管：一般用无缝钢管是用2、3、345等优质碳结钢16Mn、5MnV等低合金结构钢或4Cr、3CrMnS45Mn4MnB等合结钢热轧或冷轧制成的。、2等低碳钢制造的无缝管主要用于流体输送管道。、4Cr等中碳钢制成的无缝管用来制造机械零件，如汽车、拖拉机的受力零件。一般用无缝钢管要保证强度和压扁试验。热轧钢管以热轧状态或热处理状态交货；冷轧以热以热处理状态交货。低中压锅炉用无缝钢管：用于制造各种低中压锅炉、过热蒸汽管、沸水管、水冷壁管及机车锅炉用过热蒸汽管、大烟管、小烟管和拱砖管等。

日标型钢：
Cr4W2MoV钢的热处理工艺：要求强度、韧性较高时，采用低温淬火、低温回火工艺：淬火温度96~98℃，回火温度28~32℃，硬度6~62HRC。要求热硬性和耐磨性较高时，采用高温淬火、高温回火工艺：淬火温度12~14℃，回火温度5~54℃，硬度6~62HRC。rSiMnMoV(代号CH-1)钢为空淬微变形低合金钢、火焰淬火钢，可以利用火焰进行局部淬火，淬硬模具刃口部分。
