304 / 304L

304 is the most common 18/8 austenitic stainless steel, very widely used in the food, pharmaceutical, breweries and chemical industries. 304 stainless is very popular in the building and domestic appliance sectors. The 304L grade has a reduced carbon content. The lower carbon content will help improve corrosion resistance after welding, and minimise carbide precipitation during the welding operation. As a stainless steel 304 has very good welding characteristics. Though continuous use of 304 stainless as high temperature is not recommended occasional service of 304 stainless up to 870ºC will give good oxidation resistance.
