Precautions for powder metallurgy heat treatment
The core of heat treatment of powder metallurgy parts is temperature control. Due to the high porosity of powder metallurgy parts, deformation and cracking are easy to occur at high temperatures. Therefore, it is necessary to strictly control the heating temperature and holding time according to the heat treatment requirements of different materials to prevent thermal deformation and cracks of the parts.

Method of heat treatment of stainless steel
The current industry is getting more and more developed and the requirements for the steel industry are becoming more and more strict. In order to better meet the requirements of the market, large-diameter stainless steel pipes are heat-treated. The performance of large-diameter stainless steel pipes also increases the service life of large-diameter stainless steel pipes. The toughness of large-diameter stainless steel pipes is improved through heat treatment to increase the plasticity of large-diameter stainless steel pipes.

Principle and precautions of ultra-deep cooling treatment
The principle of ultra-cryogenic treatment is to improve the performance of metal materials by changing their crystal structure. The cryogenic treatment temperature is very low, which can make the metal atoms move freely, thus changing the crystal structure and enhancing the hardness and toughness of the material.
