The nitric acid used in these treatments will also leave the steel surface in the passive condition. The nitric acid used in these treatments will also leave the steel surface in the passive condition.

Oh and if at all possible be sure the wheel is stainless also this will keep carbon steel from being embedded in the stainless and causing rust later on. Soaking the weld joint in a bath of nitric or hydrofluoric acid will remove the heat tint with ease. Like SJones stated the stainless steel is not immune to soil corrosion.

Stainless steel one of the most used metals has higher incidences of warping due to its higher coefficient of expansion and low conductivity. To reshape steel that has suffered distortion during the welding process welders use one of the following methods. How to fix warped sheet metal after welding.

This process involves the oxidation of an acidic electrolyte on a metal surface with the help of electricity. The paste made from hydrofluoric acid and nitric acid is applied to the affected areas using a brush or spray then later removed and neutralized with a neutralizing agent. The best way to clean stainless steel after welding is through a process called electropolishing.

The electrochemical process will not only remove imperfections on the surface after welding but it will also restore the oxide layer that returns stainless steel back to its normal passive state. This is used to remove angular distortions. In the process design of welding it is necessary to adopt the right and left alternate welding method symmetrical welding method and back-step welding method and the specific principles are first inside and then outside first less and then more first short and.
