The comparison between 304 steel plate and 304L steel plate

Compared with 304 steel plate, 304L steel plate contains more nickel. And more important, 304L steel plate has much less carbon than 304 steel plate. 304L steel plate is better than 304 steel plate in pitting corrosion on welding points or other treatments. 304L steel plate is more resistant to corrosion.

304 steel plate has a wide range of applications, good corrosion resistance, heat resistance, low temperature strength and mechanical properties.The stamping bending and other hot working performance of 304 steel plate is good.It has no heat treatment hardening phenomenon.

304L steel plate has excellent resistance to grain boundary corrosion after welding or stress relief, and can also maintain good corrosion resistance without heat treatment.
