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-lessWhen to Use 308L,309L or 316L Filler MetalUse 309L (including ER309LSi) when joining mild steel or low alloy steel to stainless steels,for joining dissimilar stainless steels such as 409 to itself or to 304L stainless,as well as for joining 309 base metal.CG-12 is the cast equivalent of 309.When to Use 308L,309L or 316L Filler MetalUse 309L (including ER309LSi) when joining mild steel or low alloy steel to stainless steels,for joining dissimilar stainless steels such as 409 to itself or to 304L stainless,as well as for joining 309 base metal.CG-12 is the cast equivalent of 309.
