200 Stainless Steel Square Tube
The 200 series of stainless steel is a type of nickel-saving austenitic stainless steel that substitutes manganese for nickel (Cr 16%-19%, Mn 5%-10%, Ni 1%-4%). By alloying with manganese and nitrogen, it maintains non-magnetic properties, offers moderate corrosion resistance, and provides high cost-effectiveness, making it suitable for applications such as decorative building materials and appliance housings in the civilian sector. Typical grades include 201/202, which have better machinability than 430 stainless steel but inferior corrosion resistance compared to the 300 series.
