5. Intergranular Corrosion - all austentic stainless steels contain a small amount of carbon. At extremely high temperature, such as welding, the carbon forces local chrome to form chromium carbide around it, thus starving adjacent areas of the chrome it needs for its own corrosion protection.When welding, it is recommended you consider low carbon stainless such as 304L or 316L. 304L Stainless Steel Corrosion Resistance - TP304L 1.4307 Stress Corrosion Cracking The Alloys 304, 304L, and 304H are the most susceptible of the austenitic stainless steel to stress corrosion cracking (SCC) in halides because of their relatively low nickel content. Conditions which cause SCC are:(1) presence of halide ions (generally chloride), (2) residual tensile stresses, and (3) temperatures in excess of about 120°F (49°C).
