Document Type and Number:
Japanese Patent JP3010378
Kind Code:
B2
Abstract:
A powder metallurgy article formed from a Co-Cr-Mo alloy powder and a method for making the article are disclosed. The Co-Cr-Mo alloy powder contains, in weight percent, about 0.35% max. C, about 1.00% max. Mn, about 1.00% max. Si, about 26.0-30.0% Cr, about 5.0-7.0% Mo, about 3% max. Ni, about 0.25% max. N, about 1.00% max. Fe, about 0.01% max. of oxide forming metals, and the balance is essentially Co. Within their respective weight percent limits C and N are controlled such that they satisfy the relationship: 62.866+360.93x(%C)+286.633x(%N)-682.165x(%C)2-641.702x(%N)2>/=120.
