Alloy Steel Seamless Pipes ASTM A213 T11 Cold Drawn Boiler Tube Hot
/ Cold Finished
ASME SA213 Grade T11 alloy steel seamless tubes are known as chrome
moly tubes. ASME specification alloy steel tubes are used for high
temperature service applications. Seamless alloy steel tubes
according to ASME SA 213 Grade T11 are reheated and furnished in
full annlealed,isothermal annealed or normalized quenched and
tempered condition. ASME SA 213 Grade T11 Alloy Steel Seamless
Tubes have a typical chemistry with additions of 4.00-6.00 Chromium
and 0.45-0.65 Molybdenum. Bearing minimum tensile strength of 415
Mpa ASME SA 213 Grade T11 Tubes have minimum yield strength of 205
Mpa. Seamless Tubes have a typical chemistry with additions of
4.00-6.00 Chromium and 0.45-0.65 Molybdenum. Bearing minimum
tensile strength of 415 Mpa ASME SA 213 Grade T11 Tubes have
minimum yield strength of 205 Mpa.
