439 Stainless Tubing Exhaust Pipe 439 Stainless Steel Properties 439 Stainless Steel Tubing
Description
Type 439 is an 18% chromium, titanium stabilized ferritic stainless
steel with corrosion resistance similar to that of 304/304L
stainless steel. This grade may be used in the annealed, cold
formed or as-welded condition in applications where other stainless
steels such as Type 304/304L and Type 430 are used. Type 439 has
good weldability due to titanium stabilization and has excellent
resistance to stress corrosion cracking. Type 439 outperforms Type
409 in both oxidation and corrosion resistance and typical
applications include tubular manifolds and exhaust system
components.
