Abstract
PURPOSE: To remarkably enhance the strength of a maraging steel by adding specified elements to the steel and subjecting the steel to heat treatment and working under specified conditions.
CONSTITUTION: A maraging steel ingot contg. 3W20% Ni, 5W25% Co, 5W17% Mo, <20% W, <4.5% Ti and <2.5% Al and having ≥250kg/mm2 tensile strength is heated to ≥1,100°C to thoroughly solubilize the precipitates of the contained strengthening elements in the austenite matrix. The ingot is then hot worked at the temp. W1,000°C to make the austenite grains fine. The hot working is stopped in the temp. range of 1,000W900°C. During this time, the ingot is air- cooled, and when the temp. reaches ≤900°C, the ingot is worked again ≥2 times at ≥50% degree of working. Hardening and tempering are finally carried out to uniformly precipitate a fine intermetallic compound, whereby the material strength is increased remarkably.
