Where does the name of stainless steel pipe fittings come from? According to industry experts, stainless steel pipe fittings are a type of pipe fittings. They are made of stainless steel, so they are called stainless steel pipe fittings. They include: stainless steel elbows, stainless steel tees, stainless steel crosses, stainless steel reducers, stainless steel pipe caps, etc. According to the connection techniques, they can be divided into four categories: socket-type stainless steel pipe fittings, threaded stainless steel pipe fittings, flange stainless steel pipe fittings and welded stainless steel pipe fittings.
After stainless steel pipe fittings are processed by forming, welding and other processes, the metal molecular structure, magnetism and physical properties have changed. The air-protected solid solution process can restore the corrosion resistance affected after processing, and at the same time obtain the hardness required by stainless steel, ensuring that stainless steel is very suitable for application. Stainless steel pipe fittings after solid solution treatment have good improvement benefits:
1. Eliminate the modification phenomenon of stainless steel pipe fittings during the processing process, restore the hardness of stainless steel to below 220HV, improve the plasticity and toughness of stainless steel, and make the pipe fittings more convenient and safe in installation.
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 caused by the processing process and strengthen the austenite structure.
4. Restore the natural brightness of the surface of stainless steel materials (the difference between natural brightness and polishing brightness).
