Alloy steel boiler tubes are based on ASTM A250 standard. It covers standard specification for several grades, designated T1, T1a, T1b, T2, T11, T12, and T22, of minimum-wall-thickness, electric-resistance-welded, carbon-molybdenum and chromium-molybdenum alloy-steel, boiler and superheater tubes.
The tubes shall have a hardness not exceeding the specified values for brinell hardness and rockwell hardness numbers. When the final heat treatment is in a continuous furnace, the number of tubes of the same size and from the same heat in a lot shall be determined from the given size of the tubes.

Wärterbehandlung:
1. After welding or when cold finished, after the final cold-drawing pass, all tubes shall be heat treated and, except asprovided in 5.3.2. furnished in the full annealed, isothermal annealed, normalized, or normalized and tempered condition at the option of the manufacturer, if furnished in the normalized and tempered condition, the minimum temperingtemperature shall be 1200°F except T22 shall be tempered at 1250°minimum.
2. when grades T1, T1a, T1b and T2 are cold finished, the tubes may at the option of the manufacturer, be heat treated after the final cold-drawing pass at a temperature of 1200°F or higher, provided one of the heat treatments specified in 5.3.1 was applied after welding.
