Abstract

This specification covers hot-wrought, ferritic alloy steel bars for elevated temperature or pressure-containing parts suitable for fusion welding or both. The bars are furnished in two grades: Grade B 11 and Grade B 22. The steel shall be made by on or more of the following primary processes: open-hearth, basic-oxygen, or electric furnace. The bars shall be normalized and tempered. The heat analysis shall conform to the limits for chemical composition specified. The bars as represented by the test specimen shall conform to the tensile requirements specified.

Scope

1.1 This specification covers hot-wrought, ferritic alloy steel bars for elevated temperature or pressure-containing parts suitable for fusion welding or both.

1.2 The bars are furnished in the following grades:

Grade B 11: 1.25% chromium, 0.55% molybdenum

Grade B 22: 2.25% chromium, 1.00% molybdenum

1.3 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are for information only.
