Stainless steel elbow, Its tempering and annealing is one of the factors that determine the quality of the elbow after forming. If we grasp these two links, the elbow production will improve the production efficiency. It is called tempering to reheat the quenched elbow to a certain temperature and then cool it with a certain method. Its purpose is to eliminate the internal stress produced by quenching, reduce the hardness and brittleness, so as to achieve the expected mechanical properties. Tempering is divided into high temperature tempering, medium temperature tempering and low temperature tempering. Tempering is often used with quenching and normalizing.

Stainless steel elbow is a heat treatment method of high temperature tempering after quenching, which is called quenching and tempering. High temperature tempering refers to tempering between 500 and 650. Quenching and tempering can adjust the properties and materials of steel to a great extent. Its strength, plasticity and toughness are good, and it has good comprehensive mechanical properties.
Stainless steel elbow is to eliminate the size and shape changes of precision measuring tools or molds and parts in long-term use. After low-temperature tempering (low-temperature tempering temperature 150-250), the workpiece is often reheated to 100-150 and kept for 5-20 hours before finishing. This treatment is called aging to stabilize the quality of precision parts.
