Introduction
Stainless Steel Alloy Duplex 2202 aka DX2202 is a stainless steel with austenitic-ferritic properties. It proffers light resistance to corrosion alike Type 304L. The element has many key characters which are as follows
High mechanical strength
Serve a temperature range between -50 °C to 300°C
Corrosion resistance property is twice to other austenitic stainless steels
