The annealing process of stainless steel elbow

The annealing of the stainless steel elbow is one of the factors that determine the quality of the stainless steel elbow. If we grasp this part, we will improve the production efficiency.
The stainless steel elbow is heated to a certain temperature and heat for a while, and then slowly cooling it, called annealing. The annealing process of the stainless steel elbow is to heat the steel to the temperature of the phase transformation or part of the transformation, and the heat treatment method after heat preservation is slow. Annealing of stainless steel elbow, in order to eliminate the defects, improve the organization to make component uniformity and refine the grain and improve the mechanical properties of the hot pressing stainless steel elbow and reduce the residual stress; at the same time, reduce hardness and improve the plasticity and toughness, improve the machining performance. Therefore, the stainless steel elbow annealing in order to eliminate and improve the previous process of the organization and the residual stress, and to prepare for the subsequent process, the annealing is a semi – finished heat treatment, also known as pre heat treatment.
