Compared with 304 and 304 l, 304 h is mainly different in carbon content.
304H has a higher carbon content than 304, and 304L has a lower carbon content than 304
The carbon content of 304 is within 0.08%
The carbon content of 304H is between 0.04 and 0.1%
The carbon content of 304L is within 0.035%
Other elements are basically the same.
304H features: rust-free, heat resistant steel, good bending and welding process performance, corrosion resistance, high endurance strength and tissue stability, good cold deformation capacity. Using temperature up to 650 ℃, oxidation temperature up to 850 ℃
The 304L material has the characteristics of better weaving and welding due to its low carbon content.
