Stainless steel tube annealing heat treatment to remove stress

Many petroleum industry factories use oil, casing, and stainless steel tube annealing heat treatment to remove residual stress and improve the overall performance of the workpiece.
Annealing heat treatment is to slowly and uniformly heat the workpiece to a certain temperature, then hold it at this temperature for a period of time, and then slowly and uniformly cool down gradually. In this process, it is important to keep the cooling rate of each part of the workpiece the same. Otherwise, after cooling, due to the difference in cooling rate of each area, residual stress will be caused again. This is especially important for products with complex shapes.

The use of induction heating equipment to remove residual stress annealing is a process technique that uses atomic atmospheric temperature to have a slight potential change to recombine the atomic position to eliminate stress. Therefore, the workpiece material stress relief annealing temperature will vary with the high temperature creep potential of the material. The material on the side of the creep. For example, alloy steels usually have an annealing temperature of 595 to 675 ° C, but high chromium alloy steels have a temperature of 900 to 1065 ° C. We can use the lower temperature and longer time to achieve the same effect as short-term, temperature-treated stress removal.
