304/304L:
304 is the standard '18/8' stainless and known to be the most versatile and most widely used stainless steel. It is chosen for its suitability for use in highly corrosive environments, resistance to chromium carbide precipitation, high formability and high weldability. 304L grade is an extra low carbon version of 304 which offers additional resistance to carbide precipitation during welding, therefore eliminating the need for post weld annealing in most cases. Applications include kitchen equipment, welded components of chemical, textile, pharmaceutical and paper processing equipment, cosmetic automotive trim, air bag inflator tubes, automotive and truck exhaust components.
316/316L:
This stainless grade is similar to that of the 304 grade, but with additions of molybdenum, greater corrosion resistance and improved high temperature strength is achieved. Corrosion resistance to lower pH and chloride solutions can be attributed to this particular grade's combination of stainless alloying elements. 316L grade is an extra low carbon version of 316 which offers additional resistance to carbide precipitation during welding, therefore eliminating the need for post weld annealing in most cases. Applications include parts exposed to marine atmospheres, furnace components, heat exchanger tubes, and exhaust manifolds.
