Abstract

The invention provides a sufficient solid solution and sufficient heating aging composite heat treatment method. The method comprises a sufficient solid solution heat treatment process and a sufficient heating aging composite heat treatment process. According to the scheme, the specific heat treatment technical problems of'one-long-one-high three-difference five-low 'of existing austenitic stainless steel heat treatment, such as poor quality stability, low qualified rate, low hardness, low mechanical property, poor consistency, long heating time, low efficiency, poor heating reliability of heat treatment equipment, short service life of high-temperature components, high cost and the like, can be solved.

Description

technical field [0001] The invention relates to the technical field of material heat treatment, in particular to a composite heat treatment method of sufficient solid solution and sufficient temperature rise 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. Therefore, alloy structural steel can easily increase the hardness of the material through quenching and tempering heat treatment methods ( or mechanical properties); and austenitic stainless steel cannot undergo high-temperature austenite structural transformation under high temperature conditions (only the strengthening phase of alloying elements can be dissolved and precipitated), so it is extremely difficult for austenitic stainless steel to undergo solid solution and aging heat treatment. Amplitude increa...
