20G钢管化学成份力学性能与用途等资料汇总20G钢管是GB/5310国标钢号（国外对应牌号：德国st45.8、日本STB42、美国SA106B），为最常用锅炉钢管用钢，化学成分和力学性能与20板材基本相同。

该钢有一定常温和中高温强度，含碳量较低，有较佳塑性和韧性，其冷热成型和焊接性能良好。

目录性能20G钢管主要用于制造高压和更高参数锅炉管件，低温段过热器、再热器，省煤器及水冷壁等；如小口径管做壁温≤500℃受热面管子、以及水冷壁管、省煤器管等，大口径管做壁温≤450℃蒸汽管道、集箱（省煤器、水冷壁、低温过热器和再热器联箱），介质温度≤450℃管路附件等。

由于碳钢在450℃以上长期运行将产生石墨化，因此作为受热面管子长期最高使用温度最好限制到450℃以下。

该钢在这一温度范围，其强度能满足过热器和蒸汽管道要求、且具有良好抗氧化性能，塑性韧性、焊接性能等冷热加工性能均很好，应用较广。

此钢在伊朗炉（指单台）上所使用部位为下水引入管（数量为28吨）、汽水引入管（20吨）、蒸汽连接管（26吨）、省煤器集箱（8吨）、减温水系统（5吨），其余作为扁钢、吊杆材料使用（约86吨）。

计算及性能20G钢管理论重量的计算方法：（外径-壁厚）*壁厚*0.0246620G高压锅炉管力学性能：用途20G钢管(Seamless Steel Tube)是一种具有中空截面、周边没有接缝的长条钢材。

钢管具有中空截面，大量用作输送流体的管道，如输送石油、天然气、煤气、水及某些固体物料的管道等。

钢管与圆钢等实心钢材相比，在抗弯抗扭强度相同时，重量较轻，是一种经济截面钢材，广泛用于制造结构件和机械零件，如石油钻杆、汽车传动轴、自行车架以及建筑施工中用的钢脚手架等。

用钢管制造环形零件，可提高材料利用率，简化制造工序，节约材料和加工工时，如滚动轴承套圈、千斤顶套等，目前已广泛用钢管来制造。

钢管还是各种常规武器不可缺少的材料，枪管、炮筒等都要钢管来制造。
