摘要
与 2 0G钢相比 ,15CrMo钢具有较好的力学性能和可焊性 ,在 3 5 0～ 40 0℃也具有较高的持久强度和蠕变能力。用 15CrMo钢替换原用 2 0G钢管制作的稠油热采注蒸汽管道和炉管 ,其腐蚀速率低 ,使用寿命长 。
CrMo steel has higher mechanical properties, better weldability, also higher strength durability and collapsing strength at 350～400℃, compared with 20G steel. The heating coil and steam injection pipeline made of 15CrMo steel, instead of 20G steel, have a low corrosion rate, long duration of service, better adoption prospects and spreading value.
