Type 439 stainless steel is a ferritic, titanium stabilized, 18% chromium alloy material with corrosion resistance that is more or less equivalent to grades 304 and 304L. This type is commonly used in applications such as exhaust system components or tubular manifolds, where Types 304 and 304L and Type 430 may also be considered adequate. The grade can be used in annealed, cold-formed, or as-welded conditions. Also, titanium stabilization allows for excellent weldability, moldability, chloride corrosion cracking, and impact resistance.

Type 439 Stainless Steel – An Overview from a San Diego Stainless Steel Slitting Company
Type 439 stainless steel is also known as ASTM XM-8. This grade is manufactured with a composition that gives it the needed corrosion resistance under a range of oxidizing conditions, especially from boiling acids and freshwater. It polishes excellently and is also well suited for deep drawing.
Compared to the 304 stainless steel series, Type 439 stainless steel has a lower elongation (about 30%). However, its corrosion resistance and strength are generally considered to be better than the 200 stainless steel materials.
This type is often used in place of grade 409 stainless steel, especially where high thermal conductivity is essential. It does not demand annealing after welding to render intergranular corrosion resistance or for the restoration of ductility. Moreover, the grade can be hardened to somewhat increase its tensile strength. It is known to hold up very well over the years, which is one of the reasons why it’s commonly used in the automotive industry.
