Heat treatment of stainless steel pipe fittings

Update:2023-01-31   View(s):308   Keywords :Heat treatment of stainless steel pipe fittings
After stainless steel pipe fittings are processed by forming, welding and other processes, the molecular structure, magnetic properties, and physical properties of the metal have changed. Through the atmosphere protection solid solution process, the corrosion resistance affected after processing can be restored, and at the same time, the hardness required by stainless steel can be obtained to ensure the optimum performance of stainless steel. Stainless steel pipe fittings after solution treatment have a good improvement effect:

1. Eliminate the modification phenomenon of stainless steel pipe fittings during processing, restore the hardness of stainless steel to below 220HV, improve the plasticity and toughness of stainless steel, and make the installation of pipe fittings more convenient and safe.
2. Restore the stress and intergranular changes in the production process of stainless steel pipe fittings, reduce the intergranular corrosion and stress corrosion of stainless steel, and enhance the corrosion resistance.
3. Remove the magnetism of stainless steel due to the processing process and stabilize the austenite structure.
4. Restore the natural light on the surface of stainless steel (natural light is different from polished light).
