2、年消耗的不锈钢中有70的是不锈钢,在我过也达到了65左右。因此开发和使用好奥氏体不锈钢对我过的工业话来说已经越来越重要了。0cr18ni9就是奥氏体不锈钢,我做的这个课题就是探讨0cr18ni9在低温贮罐制造中的性能。低温贮罐是用来储存液N液Ar液态的CO2等低温液体的容器,液态介质的特殊性能就决定了制造材料需要特殊性能,而奥氏体不锈钢0cr18ni9就具有这样的性能。低温贮罐在现在的生活、生产中使用已经越来越广泛,因此对0cr18ni9的探讨就显得越来越重要。在这篇论文中我会着重为大家阐述0cr18ni9在低温压力容器制造中的焊接性能,力学性能,使用性能和焊接工艺。在这篇论文中我会通过一个焊
3、接性试验来探讨0gr18ni9在低温压力容器中的各项性能。我的这个试验就是规格为6150300mm的两块0cr18ni9扳水平对接焊接方法就是手工电弧焊。针对这个试验做出完整的焊接工艺评定,并且根据评定要求对式样做相应的无损检验和力学性能的检验,从而来判定0cr18ni9的各项性能。关键词: 焊接性能 力学性能 使用性能 焊接工艺AbstractSteel our modern society is indispensable to a material, it can be seen as a sign of the level of industrialized countries.
