304L is more resistant to corrosion, and 304L contains less carbon.
304 widely used, with good corrosion resistance, heat resistance, low temperature strength and mechanical properties;
Punching and bending and other hot workability, no heat treatment hardening phenomenon (non-magnetic, operating temperature -196 °C ~ 800 °C).
After 304L welding or eliminating stress, its resistance to grain boundary corrosion is excellent;
In the absence of heat treatment, it can maintain good corrosion resistance, the use of temperature -196 °C -800 °C.
