After stainless steel pipe fittings are processed by forming, welding, and other processes, the metal molecular structure, magnetism, and physical properties have changed. The atmosphere protection solid solution process can restore the corrosion resistance affected after processing, and at the same time obtain the hardness required by stainless steel to ensure the best 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 processing, restore the hardness of stainless steel to below 220HV, improve the plasticity and toughness of stainless steel, and make pipe fittings more convenient and safe during installation.
2. Restore the 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 resistance.
3. Remove the magnetism of stainless steel generated during the processing process and stabilize the austenite structure.
4. Restore the natural brightness of the surface of stainless steel materials (natural brightness is different from polished brightness).
