Stainless steel and carbon steel composite and method of producing the same

摘要

A pressure-bonded composite material includes at least one layer of a stabilized low carbon steel core material and one layer of a stainless steel joined at an interface, wherein the stabilized carbon steel includes columbium (niobium) and at least one other carbide-forming element in amounts effective to prevent carbon migration from the carbon steel to the stainless steel and the composite material has a physical grain size no larger than ASTM #6.
