英标型钢：马氏体相变的强化在不锈钢中具有硬度的SUS44(2(13Cr-IC)(64-7[1V)属于马氏体系不锈钢，马氏体组织的结构非常微细，而且在其内部存在高密度的位错，若使碳过饱和固溶还能强度。另方面，经过Zui后的回火处理可以得到碳化物等析出物弥散细微分布的组织。马氏体系不锈钢用固溶碳量和加火处理可以调整其强度。，SUS42J2(13Cr-O.3C)从i~C的高温奥氏体区急冷时，发生固溶.3％C的马氏体相变，再经回火热处理就会使碳化物等析出物呈微细弥散分布。

英标型材：
PVC-U管的热变形温度较低，其维卡软化点仅在76℃左右，因此它不能在较高的温度条件下使用，一般要求输送介质的温度不得超过45℃。应根据管道的压力等级来选择相应的PVC-U管材。一共有5个压力等级，即～.6MPa，.6～.8MPa，.8～.MPa，.～.25MPa，.25～.6MPa。选择管径时要按压力等级、、流速、地理环境等因素综合考虑。通常从经济流速出发并结合其他因素来选择管径。
