锅炉钢管分子式：分子量：CAS号：性质：为无缝钢管，分低中压（6.85~9.8兆帕）锅炉用和高压（19.6兆帕）锅炉用两种。用于制造各种结构的锅炉的过热蒸汽管、沸水管、大小烟管和拱砖管。低中压锅炉钢管用钢是10和20号优质碳素结构钢；高压锅炉钢管的钢种除优质碳素结构钢外，还有铬钼和铬钼钒系合金结构钢和不锈耐热钢。热轧锅炉管的直径为22~530毫米（外径大于325毫米的系热扩径管），壁厚2~70毫米；冷拔（轧）锅炉管的直径为10~108毫米，壁厚2~13毫米。钢管分两种精确度——普通级和高级；冷拔（轧）的比热轧的高。高压锅炉钢管交货前应经过正火、回火调质处理或固溶处理，以保证足够的力学性能，并对晶粒度、显微组织、脱碳层、高温性能和表面质量均有严格要求。
