Description
304L / 1.4306 Stainless Steel Coil (L is low carbon)
Performance introduction
As a low-carbon 304 steel, its corrosion resistance is similar to that of 304 under normal conditions, but after welding or stress relief, its resistance to intergranular corrosion is excellent; it can also maintain good resistance without heat treatment Corrosion resistance, use temperature -196℃～800℃.
Scope of application
It is applied to outdoor machines in the chemical, coal, and petroleum industries that require high grain boundary corrosion resistance, heat-resistant parts for building materials, and parts with difficult heat treatment.
