FE-BASE SINTERED ALLOY HAVING SUPERIOR CORROSION AND WEAR RESISTANCES

摘要

PURPOSE:To obtain a Fe-base sintered alloy having superior corrosion and wear resistances by blending Fe with specified amounts of Cr, Ni, Mn, P, B and C. CONSTITUTION:The composition of alloy powder is composed of, by weight, 16-26% Cr, 8-16% Ni, 1-5% Mn, 0.05-1.2% P, 0.02-1.2% B, 0.05-0.5% C and the balance Fe with inevitable impurities. The alloy powder is press- compacted to form a green compact, and this green compact is sintered in a reducing atmosphere or in vacuum. The sintered compact is is aged at 500-750 deg.C so as to provide prescribed hardness.
