304L Stainless steel

304L stainless steel, also known as ultra-low carbon stainless steel, is a versatile stainless steel material that is widely used to make equipment and parts that require good overall properties (corrosion and formability).

Different about 304 and 304L

  • 304 stainless steel and 304L stainless steel are mainly composed of 18% chromium (Cr), 8% nickel (Ni); their main difference is 304L stainless steel is low carbon 304 steel, in general, 304L stainless steel corrosion resistance Similar to 304 stainless steel, but after welding or after stress relief, 304L stainless steel excellent resistance to grain boundary corrosion.
  • 304L stainless steel prices higher than 304 stainless steel, 304L stainless steel is low carbon stainless steel, mainly for the welding process. In welding, the use of 304L stainless steel can effectively reduce the welding corrosion.
  • According to the hardness standard to point out, 304 stainless steel is better than 304L stainless steel, because the level of carbon content directly affects the hardness of stainless steel. There are also 304H stainless steel series, H said high carbon content.


304/304L, double standard 304, ASTM A240

If 304L steel mechanical property can match 304, usually we can call 304/304L, or double standard 304.
