Product Description

Material summary and usage
S****3 steel is ultra-low carbon dual- phase stainless acid resistant steel. It is provided with excellent pitting corrosion and crevice corrosion resistant performances. In addition, nitrogen, as a strong element that forms and stabilizes austenite, still ensures the existence of certain amount of austenite in the structure even if after welding or heating under high temperature, and makes it difficult to form single-phase ferrite. The dual-phase proportion is not sensitive to the change of heating temperature.
