ASTM A312 253MA Stainless Steel Seamless Pipe EDC Fracking Air preheater Oil
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.
