430不锈钢是一种具有良好的耐腐蚀性能的通用钢种， 430不锈钢是具有良好的耐腐蚀性能的通用钢种，导热性能比奥氏体好，

热膨胀系数比奥氏体小，耐热疲劳，添加稳定化元素钛，焊缝部位机械性能好。430F是在430钢上加上易切削性能的钢种。

但由于430不锈钢当中的含铬量相对304要少得多，所以在硬度方面却没304那么好。

430 stainless steel is a kind of general steel with good corrosion resistance, 430 stainless steel is a general steel with good corrosion resistance,

thermal conductivity is better than austenite, thermal expansion coefficient is smaller than austenite, heat fatigue resistance,

add stabilization element titanium, weld site good mechanical performance.430F is a steel type with easy cutting performance on 430 steel.

But because the chromium content in 430 stainless steel is much less than 304, so the hardness is not as good as 304.
