15-5PH不锈钢的性能和化学成分先容

15-5PH不锈钢属于马氏体沉淀与时效硬化不锈钢,具有高强度和硬度以及优异的耐腐蚀性。化学成分分析是平衡的,可以产生*小的δ铁素体,所以还具有优异的横向韧性和延展性,以及良好的锻造性。

15-5PH的制造特性和其他沉淀硬化不锈钢材质相似, 它们可以通过单步老化硬化,低温处理。

该材质不锈钢可用于阀部件、配件和紧固件、锻造轴和齿轮、发动机部件、化学工艺设备、造纸设备以及飞机和核反应堆的部件。

15-5PH不锈钢

在锻造时,该不锈钢材质应均匀加热至1180 /1205℃,并锻炼1小时。为了获得*佳的晶粒尺寸和机械性能,锻造材料应在进一步加工之前将其风冷至32℃以下。硬化前必须对该不锈钢材料进行固溶处理。

热处理
15-5PH
一般在溶液处理条件中提供,可以通过将溶液处理的材料加热至480℃至620℃的温度并硬化1-4小时,具体取决于温度,然后空气冷却。

1040+/-14℃的温度下加热1-2小时,冷却至32℃以下,从而完全转化为马氏体。但此时材料由于韧性较差,冲击强度差,应力腐蚀开裂敏感,材料不能用于溶液处理条件。

15-5PH不锈钢切削加工性较好,在溶液处理和各种老化硬化条件下都容易加工。当以与302不锈钢和304不锈钢相似的方式对材料机械进行固溶处理时,随着硬化温度的升高,加工性提高。*佳切削性从条件1150M获得。

该材料的焊接性也非常不错,可以通过屏蔽熔接和电阻焊接工艺获得令人满意地焊接效果。因为碳吸取的可能性,不推荐采用氧乙炔焊接。焊接接头应设计成*小化应力。在溶液处理条件下的焊接通常是令人满意的,但是如果预期焊接应力很高,*好在H1150焊接过时的状态,焊接前通常不需要进行预热。
