Three methods to prevent pollution of stainless steel castings
In the process of using stainless steel castings, it will be polluted, which is not conducive to our use. How can we prevent it from being polluted? This article will introduce three methods to prevent pollution of stainless steel castings.
1. High voltage and high current density impulse method
It is to use high-voltage electric shock at the early stage of oxidation of stainless steel castings, so that the oxidized parts are reconnected into pieces by electric shock.
2. Surface grinding method
This method is to fill the gap left by the oxidized part with the polished aluminum mill, so that the resulting gap is connected together as a bridge.
3. Surface shot peening
This method is to knock the gap with a round hammer, and close it by knocking, so as to achieve the purpose of connecting into pieces.
