Stainless Steel 304L Flanges are covered by numerous constructions or use of equipment made from these alloys for certain circumstances. Examples include uses in sanitary, cryogenic, food and beverage, and pressure-containing environments. For welded items that may be exposed to elements that could lead to intergranular corrosion in use, type 304L is employed.
Chromium carbides may form in grain boundaries when 18-8 austenitic stainless steels are exposed to temperatures in the 800°F to 1500°F (427° to 816°C) range. When these steels are subjected to hostile environments, they become "sensitized" and vulnerable to intergranular corrosion. The carbon content of 304 may make it possible for sensitization to develop from the heat-affected zones of autogenous welds. Due to this, applications where the material is used in its as-welded state, are favoured for the low carbon Type 304L alloy. Low carbon content prolongs the amount of time needed for dangerous levels of chromium carbides to precipitate, but it does not stop the precipitation reaction for material maintained for extended periods of time at the temperature range for precipitation.
