Performance introduction
As a low-carbon 304 steel, under normal conditions, its corrosion resistance is similar to that of 304, but after welding or stress relief, its resistance to grain boundary corrosion is excellent; it can also maintain good performance without heat treatment Corrosion resistance, use temperature -196 ℃ ～ 800 ℃.
Scope of application
Used in chemical, coal, and petroleum industry outdoor open-air machines with high requirements for resistance to grain boundary corrosion, heat-resistant parts for building materials and parts with difficult heat treatment.
