The only difference is the level of carbon content, so there will be a little difference more or less in the application filed, but the overall application is the same.
304L has lower carbon content and better corrosion resistance. But 304 of the strength is higher than 304L, so 304 has a higher strength than 304L, and 304H has the best strength, because the carbon content is the highest among the three.
304 can be widely used in various departments, various fields. 304L is mainly used in welding and other fields. 304H is mainly used in high temperature resistance, corrosion resistance and other fields, also used in fields such as welding, bending, and cold deformation ability is very good, has a very high stability and enduring strength, can work in the high temperature of 650 degrees Fahrenheit.
