Ferritic stainless steel with excellent oxidation resistance, good high temperature resistance and good plasticity

摘要

Patent specification: "Ferritic stainless steel with excellent oxidation resistance, good high temperature resistance and good plasticity". Ferritic stainless steels with good oxidation resistance, good high temperature resistance and good plasticity are produced with the addition of ti and low al content for room temperature plasticity resulting from equiaxized grain structures as melt. columbium (niobium) and copper are added for high temperature resistance. Silicon and manganese are added for oxidation resistance. ferritic stainless steels provide better oxidation resistance than 18cr-2mo and 15cr-cb-ti-si-mn ferritic stainless steels. moreover, they are generally less expensive to produce than 18cr-2mo.
