What is the property of 304L stainless steel?

As a low-C 304 steel, in general, 304L’s corrosion resistance is similar to that of 304, but after welding or stress relief, 304L stainless steel has excellent resistance to grain boundary corrosion;304L stainless steel can also maintain good performance without heat treatment Corrosion resistance, use temperature -196 ℃ ～ 800 ℃.

304L stainless steel is mainly used in chemical, coal, and petroleum industry outdoor and open-air machines with high requirements on grain boundary corrosion resistance, heat-resistant parts for building materials, and parts with difficult heat treatment.
