Document Type and Number:
Japanese Patent JPS61113742
Kind Code:
A
Abstract:
PURPOSE: To obtain the titled alloy having high hardness at high temp., satisfactory corrosion resistance and superior weldability by specifying a composition consisting of C, Si, Cr, Al, Ti, B, W, Co and Ni.
CONSTITUTION: This high-hardness heat-resistant alloy consists of, by weight, <0.03% C, ≤1.0% Si, 13W17% Cr, 3W7% Al, 0.5W3% Ti, 2W4% B, 3W7% W, 7W35% Co and the balance Ni with inevitable impurities and has a low coefft. of thermal expansion, a uniform metallic structure and superior weldability. The alloy is suitable for use as a material for the filled part of a valve rod for a diesel engine.
