SA 209 T1

 Seamless carbon molybdenum alloy steel boiler and superheater tubes.


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.

ASTM A209

ASTM A209 cover several grades of minimum wall thickness seamless carbon molybdenum alloy steel, boiler and superheater tubes.

This specification covers tubes 1/2 to 5 in. [12.7 to 127 mm] inclusive, in outside diameter and 0.035 to 0.500 in. [0.9 to 12.7 mm], inclusive, in minimum wall thickness.

An optional supplementary requirement is provided and, when desired, shall be so stated in the order.

The values stated in either inch-pound units or SI units are to be regarded separately as standard. Within the text, the SI units are shown in brackets. The values stated in each system are not exact equivalents; therefore, each system must be used independently of the other. Combining values from the two systems may result in nonconformance with the specification. The inch-pound units shall apply unless the "M" designation of this specification is specified in the order.
