The role of heat treatment of stainless steel pipe fittings

After stainless steel pipe fittings are processed by processes such as forming and welding, the metal molecular structure, magnetic properties, and physical properties change. The atmosphere-protected solid solution process can restore the corrosion resistance affected after processing, and at the same time obtain the required hardness of stainless steel to ensure the optimal performance of stainless steel. Stainless steel pipe fittings after solid solution treatment have good improvement effects:

1. Eliminate the modification phenomenon of stainless steel pipe fittings during the processing process, reduce 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 safer.
2. Restore stress and intergranular changes in the production process of stainless steel pipe fittings, reduce intergranular corrosion and stress corrosion of stainless steel, and enhance corrosion prevention capabilities.
3. Remove the magnetism generated by the stainless steel processing process and stabilize the austenite structure.
4. Restore the natural brightness on the surface of stainless steel materials (natural brightness is different from polished brightness).
