What is the difference between vacuum heat treatment and quenching

Vacuum heat treatment is a new heat treatment technology combining vacuum technology and heat treatment technology. The vacuum environment where vacuum heat treatment is located refers to the atmospheric environment under one atmosphere pressure, including low vacuum, medium vacuum, high vacuum and ultra-high vacuum. Vacuum heat treatment actually belongs to atmosphere controlled heat treatment.

Vacuum heat treatment refers to all and part of the heat treatment process in the vacuum state, vacuum heat treatment can achieve almost all conventional heat treatment can be involved in the heat treatment process, and the quality of heat treatment is greatly improved. Compared with the conventional heat treatment, the vacuum heat treatment can achieve no oxidation, no decarburization, no carburization, can remove the phosphorus chip on the workpiece surface, and have degreasing and degassing, so as to achieve the effect of bright surface purification.

Quenching is a traditional heat treatment method (including quenching, normalizing, tempering, annealing, aging, etc.), which is to heat the steel pieces to the austenitizing temperature and keep them for a certain time, and then cool them at a rate greater than the critical cooling rate, so as to obtain the non-diffused transformation structure. Quenching can be done by vacuum heating or by other relatively simple and inexpensive heating methods.
