介绍
Stainless steels are high-alloy steels with good corrosion resistance due to large amounts of chromium present in them. Most of the stainless steels contain about 10% of chromium.
Stainless steels are available in three different groups based on their crystalline structure. These groups include martensitic, austenitic and ferritic. The combination of martensitic and ferritic steels forms a fourth group of stainless steels known as precipitation-hardened steels.
Grade 410S stainless steel is a non-heat treatable version of grade 410 stainless steel.

Fabrication and Heat Treatment
退火
Grade 410S stainless steel is annealed at 649-760°C (1200-1400°F) and then cooled in air.
冷工作
常用的冷工作方法用于410级不锈钢。
焊接
410级不锈钢可以通过常用的焊接方法焊接。将工件预热至177-204°C（350-400°F），以防止开裂。
Machinability
尽管在热处理和冷绘制条件下获得了更好的结果，但可以在退火状态下加工410级不锈钢。
Hardening
410级不锈钢不会通过热处理对硬化做出反应。
热工作
Grade 410S stainless steel can be hot worked between 1093 and 1204°C (2000 and 2200°F). Hot working below 899°C (1650°F) is not recommended for grade 410S stainless steel.
