chemical composition:C：≤0.08 ，Si ：≤1.0 Mn ：≤2.0 ， Cr ：18.0～20.0 ，Ni ：8.0～10.5， S ：≤0.03 ，P ：≤0.035 N≤0.1。
304L is more corrosion-resistant and has less carbon content.
304 has a wide range of uses, with good corrosion resistance, heat resistance, low temperature strength, and mechanical properties; Good hot working such as stamping and bending, without heat treatment hardening (non-magnetic, service temperature - 196 ° C~800 ° C).
After welding or stress relief, 304L has excellent resistance to grain boundary corrosion; Even without heat treatment, it can maintain good corrosion resistance at temperatures ranging from -196 ° C to 800 ° C.
