ASTM A213 T2 T5 T11 T12 Alloy Seamless Steel Tube Carbon Steel Pipe

Alloy Steel Pipes
An Alloy Steel Pipe is used in applications which require moderate corrosion resistance properties with good durability and at an economical cost. To simply put it, alloy pipes are preferred in those areas where carbon steel pipes may fail.
