S30408 stainless steel seamless pipe has a variety of processing techniques during the processing. The processing of S30408 stainless steel seamless pipe can improve its performance and appearance. Therefore, several common processing techniques are shared below.

1. Bright solid solution

   S30408 stainless steel seamless pipe must undergo solid solution treatment at 1050°C after the forming and welding process to eliminate the internal stress caused by deformation of the S30408 stainless steel seamless pipe, while reducing stress corrosion and restoring the intergranular intergranularity during the welding process of pipe fittings. Variety.

   2. Gas shielded welding

   When S30408 stainless steel seamless pipe is welded under gas protection, the chromium and nickel on its surface will not be oxidized and can retain its original characteristics and corrosion resistance.

   3. Pickling and Passivation

   The pickling and passivation of S30408 stainless steel seamless pipe can produce a thin, dense and hard passivation film on the inner and outer walls. The function of this passivation film is to prevent the steel pipe from corrosion.

   4. Sealing materials

   The sealing material determines the service life of S30408 stainless steel seamless pipe, so you should choose good quality.
