stability of tempering 回火稳定性高
Tempering stability of X80 steel is higher,its mechanical properties is stable,in addition,mechanical properties showed certain regularity along with tempering temperature variety. At 650℃ tempering,strength and plasticity change obviously.
试验结果表明,X80管线钢在930℃时已经能够完全奥氏体化,并获得板条状马氏体组织,且X80管线钢回火稳定性较高,力学性能相对稳定,并且随回火温度变化呈现出一定的规律性,在650℃回火时,其强度和塑性变化较为明显。
