Why does stainless steel rust after welding? - Cougartron

Stainless Steel is Highly Resistant to Corrosion but can Still Rust.The general perception towards stainless steel is that it is a super alloy that never rusts.Well,this assumption is anything but true.The reality is that stainless steel does rust.The word stain-less does notWhat forms of corrosion can occur in stainless steels?It is avoided by choosing a low carbon grade the so-called 'L' grades or by using a steel with Titanium or Niobium which preferentially combines with Carbon.Galvanic corrosion - If two dissimilar metals are in contact with each other and with an electrolyte e.g.water or other solution,itWelding-steel low carbon and low alloy Materials and Are there problems in Welding-steels? Full knowledge of the material and its condition will determine if and which problems are likely to crop up in welding.This knowledge may affect Process and parameters.Hardened and tempered low alloy steels are likely to lose their mechanical properties (strength and hardness) during welding.
