不锈钢装潢管厂家为了防止表面淬火时变形和开裂，可以从热处理工艺方面改进。

    ①淬火温度尽量取下限，加热时间尽可能缩短。
    ②钢的原始组织要均匀，消除加工应力。
    ③合理确定淬硬层的深度和分布。
    ④对某些变形有规律的表面淬火工件，用预先处理来抵消表面淬火时的变形。
    ⑤保证淬硬的前提下，尽量选用较缓慢的冷却，表面淬火后及时回火。感应淬火件可采用局部冷却的方法控制变形，如薄壁齿轮为了在感应淬火时防止内孔胀大，可同时内孔喷水。有的工件可采用预热的方法减少变形。
    ⑥在加热时要特别注意局部过热，防止淬火裂纹产生。对于工件尖角进行倒角，对于分布在工件表面的油孔、螺纹孔、销孔需要在孔内堵塞逆磁性材料，以屏蔽磁力线的密集。
    ⑦要保证加热和冷却均匀，正确使用定位卡具和合理设计喷水圉。
    ⑧表面淬火后及时回火消除内应力。

不锈钢 是一种合金，它没有一个能准确说出的密度。
如果能知道它的各成份的比例，通过计算才能得出结果。
按主要化学组成分为铬不锈钢、铬镍不锈钢和铬锰氮不锈钢等。它们的密度都不相同，即使是同一种材质，才会因各组成部分的不同而不同。
下面介绍一般不锈钢的密度计算
重量(kg)=厚度(mm)*宽度(m)*长度(m)*密度值
