Papua New Guinea Low-Carbon Stainless Steel 304L Sheet and Coil
304 L is a low-carbon 304 steel. Corrosion resistance is similar to 304 in normal conditions, but it has good intergranular corrosion resistance after welding or stress relief. After processing, it still retains corrosion resistance without annealing and is generally used below 4 ° C (non-magnetic, operating temperature -196-800 ° C)

Scope of application
Applicable Uses
Suitable for machinery, building materials, heat-resistant components, and parts that cannot be heat treated in the chemical, coal, and petroleum industries that require high corrosion resistance, such as water heaters, heat exchangers, LNG tanks, etc
Product Advantage
1) Excellent resistance to intergranular corrosion
2) Corrosion resistance is equivalent to 304 (without annealing after processing, corrosion resistance is still retained). 3) It is generally used below 400 ℃ (non-magnetic, operating temperature -196-800 ℃)
Excellent performance after welding or stress relief
