What does the L mean in 304L stainless steel?

extra-low carbon
In grade 304 stainless, the maximum carbon content is set at 0.08%, whereas grade 304L stainless steel has a maximum carbon content of 0.03%. The “L” in 304L can be interpreted as meaning extra-low carbon.

Is 304L corrosion resistant?

Alloy 304/304L resists atmospheric corrosion, as well as, moderately oxidizing and reducing environments. The alloy has excellent resistance to intergranular corrosion in the as-welded condition. Alloy 304/304L has excellent strength and toughness at cryogenic temperatures.

What’s the difference between Type 304 and 304L stainless steel?

Type 304L stainless steel is an extra-low carbon version of the 304 steel alloy. The lower carbon content in 304L minimizes deleterious or harmful carbide precipitation as a result of welding. 304L can, therefore, be used “as welded” in severe corrosion environments, and it eliminates the need for annealing.

What’s the carbon content of AISI 304L stainless steel?

AISI 304L stainless steel is an ultra-low carbon version of SS 304 (Carbon content: ≤ 0.08 %). “L” is short for “Low carbon” and the maximum carbon content is 0.03%. The main purpose is to prevent carbide precipitation and improve weldability and corrosion resistance.

What’s the difference between 304H and 304L austenite?

304H , the H refers to the high temperature, high carbon content makes sure it can meet the high temperature requirements, GB150 (A Chinese standard)requires austenitic steel with 525 degrees or higher, the carbon content of should not be less than 0.04%, their high temperature strength is better than pure austenite.

What are the physical properties of ss304l stainless steel?
