Abstract
A process of laser welding high carbon martensitic stainless steel components and austenitic stainless steel components by a stabilized ferritic stainless steel fusion zone modifier in the weld joint, and articles formed therefrom. The stabilized ferritic stainless steel fusion zone modifier comprises, in terms of weight percentage, from about 10% to about 35% chromium, and at least one element selected from the group consisting of no more than about 1.5% titanium and no more than about 1.5% columbium. The stabilized ferritic stainless steel fusion zone modifier present in the fusion zone inhibits and prevents solidification cracks and micro-fissures from forming in the weld joint, and assists immunity to environmental degradation.
