304L stainless steel grade 304 austenitic chromium-nickel steel strip

304L (UNS S30403) is an ultra-low carbon variant of 304 (carbon ≤0.03%), which reduces the risk of intergranular corrosion in the welding heat affected zone by reducing the carbon content, while retaining the corrosion resistance and formability of austenitic chromium nickel steel, making it suitable for manufacturing welded parts of chemical equipment.

Compared with 304 stainless steel, it has better stability in high temperature or chlorine containing media, but slightly lower strength; Attention should be paid to the tendency of cold work hardening during processing, which is suitable for fields such as food processing and environmental protection equipment that require acid and corrosion resistance and frequent welding.
