ASME SA209 T1a Seamless Carbon-Molybdenum Alloy Steel Tube Minimum Wall Thickness

ASTM A209 Grade T1a Alloy Steel Seamless Tubes are Carbon Steel Tubes with subsequent addition of chromium, molybdenum and sometimes vanadium are known as chrome moly Tubes.

ASTM Specification alloy steel Tubes are used for high temperature service applications. Seamless Alloy Steel Tubes according to ASTM A209 Grade T1a are reheated and furnished in full annlealed,isothermal annealed or normalised quenched and tempered condition.

ASTM A209 Grade T1a Alloy Steel Seamless Tubes have a typical chemistry with additions of 0.44-0.65 Molybdenum.

Bearing minimum tensile strength of 365 Mpa ASTM A209 Grade T1a Tubes have a minimum yield strength of 195 Mpa.
