Overciew
Alloy 253MA has excellent resistance to oxidation， corrosion and heat. It is able to withstand temperatures up to 1150°C while maintaining high strength and toughness at elevated temperatures. In addition， it has good weldability， machinability and manufacturability. As a result， it is widely used in the manufacture of nickel alloys and stainless steels in high temperature， corrosive and stressful environments.
