合金管的材质大致有：16-50Mn、27SiMn、20-40Cr、12-42CrMo
16Mn 12Cr1MoV T91 27SiMn 30CrMo 15CrMo 20G Cr9Mo 10CrMo910 15Mo3 15CrMoV 35CrMoV 45CrMo
合金管（Alloy pipe）是无缝钢管的一种，合金管分为结构用无缝管及高压耐热合金管。主要区别于合金管的生产标准及其工业，对合金管进行退火调质改变它的机械性能。达到所需要的加工条件。其性能比一般的无缝钢管多变利用值较高，合金管化学成分中含Cr比较多，耐高温、耐低温、耐腐蚀的性能。普碳无缝管中不含合金成分或者合金成分很少，合金管在石油、航天、化工、电力、锅炉、军工等行业的用途比较广泛的原因因为合金管的机械性能多变化好调整。
