The heat treatment process involves the controlled application of heat to change the physical (and sometimes chemical) properties of the metal, noting the size-changing effect of the heat treated metal; Before exploring the unintended negative consequences of metal part size, let's discuss some of the benefits of heat treatment and annealing.
There are many important reasons for heat treatment. According to the method used, heat treatment of metal makes the material harder or softer, more or less brittle, stronger or weaker. Based on the desired results, the wuxi heat treatment approach is summarized as: changing the temperature of the treated material, changing the length of time that heat is applied, and controlling how long the material is cooled. The manner in which heat is applied and removed affects the yield strength and hardness of the final product.
For example, stainless steel is usually treated to increase its hardness; On the downside, it may also become more vulnerable. In contrast, stainless steel can be heat-treated to increase its ductility, which helps to minimize cracking and improve workability; However, the process may also reduce the hardness of steel. Thus, achieving stainless steel with desired properties - such as high tensile strength but relatively low brittleness - may require multiple treatments at different temperatures and time lengths.
