Spring has been very common in people’s daily production and life, ranging from planes, trains and cars to household appliances and daily necessities, and even children’s stationery for school. It can be seen how important spring is to our life.
For a professional spring manufacturer, the most basic production goal is to infinitely pursue the high quality of products. Therefore, in order to improve the performance of the spring, it is often assisted by pre heat treatment, that is, the process of strengthening the quality of spring steel is used to further strengthen the spring.
In fact, the so-called pre heat treatment is what we often call annealing. It is to heat the steel to a certain temperature and keep it warm for a period of time, and then cool it slowly. Annealing of steel is a heat treatment method in which the steel is heated to the degree of phase transformation or partial phase transformation, and then cooled slowly after heat preservation. The purpose is to eliminate the structural defects of the spring, improve the structure, homogenize the composition and refine the grain, improve the mechanical properties of the steel and reduce the residual stress; At the same time, it can also reduce the hardness, improve its plasticity and toughness, and improve the cutting performance. Therefore, annealing is not only to eliminate and improve the structural defects and internal stress left by the previous process, but also to prepare for the subsequent process.
