Packaging with the formation process of austenitic steel and the meaning of a degree

Packaging steel strip of austenitic formation process and the degree of significance is to point to in heating and cooling of heat treatment of steel, the steel internal organization and crystal structure change. Packaging steel strip for the purpose of heat treatment is to obtain the desired microstructure and mechanical properties, is to play a potential performance metal materials is extremely effective method, to understand the influence of heat treatment on the microstructure and mechanical properties of steel strip packing, according to the working conditions of packing tape, high technical requirements and meet its service life, etc. , must be reasonable material selection, considering both economic, and technical. Economy refers to the packaging requirements of the use of steel strip for, with low cost of materials; And mainly technical processing is convenient, easy to machining processing manufaturability good, qualified service conditions, has a certain life, at the same time forged material, welding, forming, heat treatment, etc. Packing heat treatment process of steel strip is consists of three stages: heating, heat preservation and cooling, according to the requirements of the use of heating temperature, cooling way, and different, heat treatment is usually divided into annealing, normalizing, quenching and tempering process, to explore the rule of organizational change when heating and cooling heat treatment principle.
