MATERIALS SYSTEM FOR HIGH STRENGTH CORROSION RESISTANT BIMETALLIC PRODUCTS

摘要

A specific material system for bimetallic products is produced by diffusion bonding an age-hardenable low alloy steel with austenitic stainless steel at an elevated temperature, followed by a two step austenitizing and aging process. the resulting material combination is characterized by desirable metallurgical and structural properties in the low alloy steel component and by high corrosion resistance in the stainless steel component with virtual elimination of detrimental carbon migration across the diffusion bond from the low alloy steel to the austenitic steel.
