16mn无缝钢管377*35规格表(无锡低合金钢管化学成分)
16mn无缝钢管377*35规格表(无锡低合金钢管化学成分)——————---无锡豪鑫天
16Mn低合金钢管是:低合金高强度结构钢:Mn含碳量为0.1%-0.25%,加入主要合金元素锰、
硅、钒、铌和钛等;它的含合金总量<3%。按强度分为300、350、400和450MPa等4个级别。主要有Q295、Q345、Q390、Q420、Q460。:“Q”是屈服的“屈”字的汉语拼音大写字头,其后数字为该牌号最小屈服点(σs)值,其后的符号是按照该钢杂质元素(硫、磷)含量由高到低并伴随碳、锰元素的变化而分为A、B、C、D四等。其中A、B级钢通常称16Mn
C:0.12~0.20; Mn:1.20~1.60; Si:0.20~0.55; 抗拉强度:470~660牛/平方毫米; 屈服强度:275~345牛/平方毫米; 伸长率:21%。具体值要根据钢材的厚度或直径,以上数据对应钢材的厚度或直径为:16~100mm
,用于桥梁的专用钢种为“16Mnq”,汽车大梁的专用钢种为“16MnL”,压力容器的专用钢种为“16MnR”。
