摘要 |
A weld filler metal alloy composition and a method for welding stainless steel components into a final assembly includes the steps of: austenitizing the stainless steel components to be welded at a temperature of 1800° F.-2000° F.; applying, using conventional arc welding techniques a solid wire of the filler metal alloy comprising in % by weight: up to 0.02% carbon; up to 0.8% manganese; up to 0.02% phosphorus; up to 0.015% sulfur; up to 0.6% silicon; 4.5-5.5% nickel; 0.4-0.7% molybdenum; 10-12.5% chromium; up to 0.1% copper; balance essentially iron and incidental impurities; and tempering the welded assembly welded at a temperature of 930° F.-1300° F. A second tempering step conducted at a temperature of 1095° F.-1145° F. may follow. The welding method can be used to make compressor impellers (6). The compressor impeller components comprise 13Cr-4Ni stainless steel. |
