What is SS430?
SS430 is a low-carbon plain chromium, ferritic stainless steel without any stabilization of carbon and nitrogen with titanium or niobium. … Being a ferritic stainless steel, SS430 is unsuited for use in cryogenic applications as brittle fracture could occur at sub-zero temperatures.
Is 304 or 430 stainless better?
Stainless steel as a whole is corrosion resistant however, different grades perform better than others. The introduction to nickel in 304 makes it a much more corrosion resistant grade than 430 however, it does make it more expensive. Where cost is a larger factor than life span, 430 may be more suitable.
