Hot Rolled Seamless Alloy Steel Pipe , Heat Exchanger Seamless Tube
Pipe T12
Seamless Alloy Steel Tubes according to ASME SA 213 Grade T12 are
reheated and furnished in full annlealed,isothermal annealed or
normalized quenched and tempered condition. ASME SA 213 Grade T12
Alloy Steel Seamless Tubes have a typical chemistry with additions
of 0.80-1.25 Chromium and 0.44-0.65 Molybdenum. Bearing minimum
tensile strength of 415 Mpa ASME SA 213 Grade T12 Tubes have
minimum yield strength of 220 Mpa.
