Abstract (en)
[origin: WO2014036091A1] Ferritic stainless steels with good oxidation resistance, good high temperature strength, and good formability are produced with Ti addition and low A1 content for room temperature formability resulting from equiaxed as-cast grain structures. Columbium (niobium) and copper are added for high temperature strength. Silicon and manganese are added for oxidation resistance. The ferritic stainless steels provide better oxidation resistance than ferritic stainless steels of 18Cr-2Mo and 15Cr-Cb-Ti-Si-Mn. In addition, they are generally less costly to produce than 18Cr-2Mo.
