MATERIAL FOR BUILD-UP WELDING HAVING EXCELLENT CORROSION RESISTANCE, WEAR RESISTANCE AND SEIZURE RESISTANCE AND COMPOSITE TOOL

摘要

PROBLEM TO BE SOLVED: To provide a material for build-up welding which has excellent corrosion resistance, wear resistance and seizure resistance in hot and cold working, and a composite tool including a roll and a roller whose surface layer has been subjected to build-up welding using the material. ;SOLUTION: The material for welding or thermal spraying has a composition containing, by mass, 1.0 to 4.5% C, ≤0.5% Si, ≤1.0% Mn, 15.0 to 30.0% Cr, 1.0 to 20.0% Co and 5.0 to 25.0% V, and the balance Fe with inevitable impurities. In the composite tool having excellent corrosion resistance, wear resistance and seizure resistance, the surface layer part has been subjected to build-up welding using the above material.;COPYRIGHT: (C)2003,JPO
