ATI Steel ATI 436S™

Generic Family: Steel - Wrought - Stainless - FerriticSupplied by: Allegheny Technologies Incorporated
ATI 436S™ alloy is a single phase ferritic stainless steel in the same family of alloys as Type 409 and Type 439. The ATI 436S alloy typically contains 17.3% chromium and 1.2% molybdenum which provide improved general corrosion and pitting resistance compared to Type 409 (11% Cr), Type 430 (16% Cr) and Type 439 (18% Cr) ferritic alloys. The ATI 436S™ alloy is less resistant to pitting and crevice corrosion than Type 444 alloy (18% Cr - 2% Mo). Like all ferritic stainless steels the ATI 436S alloy provides excellent resistance to stress corrosion cracking in the presence of chlorides. It is stabilized with titanium for resistance to intergranular corrosion. Formability and weldability of the ATI 436S alloy are very good in common with ATI 409™ and ATI 439™ alloys. These characteristics make the ATI 436S™ alloy an excellent candidate for use in automotive exhaust systems as well as other applications where resistance to chlorides and mild corrosives, combined with fabricability, are needed.
