Abstract

The invention provides a sufficient solid solution and sufficient heating and cooling variable-temperature aging heat treatment method. The method comprises a sufficient solid solution heat treatment process, a sufficient heating aging heat treatment process and a sufficient cooling variable-temperature aging heat treatment process. According to the scheme, the problems that existing austenitic stainless steel heat treatment is poor in quality stability, low in qualified product rate, low in hardness, low in mechanical property, poor in consistency, long in heating time, low in efficiency, heat treatment equipment is poor in heating reliability, high-temperature components are short in service life, the cost is high, and other special heat treatment technology problems can be solved.

Description

technical field [0001] The invention relates to the technical field of heat treatment of materials, in particular to a heat treatment method for sufficient solid solution and sufficient temperature rise and fall, variable temperature aging and aging. Background technique [0002] The heat treatment principles of austenitic stainless steel and alloy structural steel are completely different: alloy structural steel can undergo high-temperature austenite transformation under high temperature conditions (good heat treatment process), therefore, alloy structural steel is very easy to pass through quenching and tempering heat treatment methods The hardness (or mechanical properties) is greatly improved; while austenitic stainless steel cannot undergo high-temperature austenite transformation under high temperature conditions (poor heat treatment process), therefore, it is extremely difficult for austenitic stainless steel to undergo heat treatment methods such as solid solution and...
