Difference among 304,304L,304H stainless steel

share with


ASTM 304,304L,304H stainless steel are commonly used in stainless steel,we can offer 304,304L,304H stainless steel stock,and a variety of 304,304L,304H stainless steel.Here is difference among 304,304L,304H stainless steel.

304H and 304L and 304 compared to the main content is different from carbon.

304H high carbon content than 304, 304L low carbon content than 304

304 within the carbon content of 0.08%

304H between the carbon content of 0.04-0.1%

304L inside the carbon content of 0.035%

Other elements in basically no difference.

304/304L/304H chemical composition


Mechanical properties of 304/304L/304H stainless steel


304 stainless steel have good welding characteristics,post-weld annealing is not normally required to restore the excellent performance of these grades in a wide range of mildly corrosive conditions.

304L stainless steel does not require post-weld annealing and finds extensive use in heavy-gauge components where freedom from carbide

precipitation is often required.

304H stainlesssteelwith higher carbon content, is normally specified where good mechanical properties at elevated temperatures are required.

the higher carbon content may lead to sensitization with a concomitant loss of corrosion resistance in a corrosive environment welding procedures should be selected with care.

304H features: heat-resistant stainless steel, with good bending, welding performance, corrosion resistance, high strength and lasting organizational stability, cold deformation capacity is very good. Operating temperature up to 650 ℃ , anti-oxidation temperature up to 850 ℃

304L type material because low carbon content for better weaving and welding characteristics.

Compared with 304 and 304L 304H, just different carbon content.

304 within the carbon content of 0.08%, 304H between the carbon content is 0.04-0.1%, 304H carbon content of 0.035%, the content of other elements basically no difference.
