摘要

A chrome-nickel steel process which can be quenched by precipitation, characterized by forming a melt containing 11 to 13% chromium, 9 to 11% nickel, 1.5 to 3% molybdenum being from 20 to 23% the sum of the contents of nickel and molybdenum plus 0.8 times the content of chromium, at least one of titanium and niobium, the titanium content being from 0.1 to 0.5% and being the niobium content from 0.05 to 1%, from 0.5 to 1.6% aluminum, the sum of the aluminum and titanium content being not more than 1.9% and being at least 5: 1 the ratio of the nickel content to the sum of the aluminum and titanium contents, carbon in an amount of up to 0.03%, from 0 to 0.2% manganese and from 0 to 0.2% silicon, being the rest of the mass, except impurities and incidental elements, iron, and allow the mass to solidify to form steel.
