304 304L 304H belongs to austenitic stainless steel, it is the most widely used in the 300 series materials. On the whole, the 304 304L 304H has very similar characteristics, the only difference lies in 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.

From the application: 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

Details for 304H material: 304H is a kind of stainless steel, with good bending, welding process performance, corrosion resistance, high durability and organizational stability, cold deformation ability is very good. The highest temperature can reach 650 DEG C, and the oxidation resistance is up to 850 DEG C
