Stainless Steel for Automotive Exhaust
THERMAK? 17 Stainless Steel has excellent high temperature strength, thermal fatigue and oxidation resistance. It is stabilized with titanium and niobium and exhibits dramatic creep resistance. The dual stabilization prevents carbide sensitization exposure and makes the alloy thermally non hardenable. The improved thermal fatigue performance over other intermediate and high chrome ferritic stainless steels facilitates vehicle light weighting efforts for hot-end exhaust components. Since THERMAK?17 does not contain any molybdenum, it may represent an opportunity for savings for applications where Type 444 is currently supplied.
