Organization: ASTM
Publication Date: 31 August 1990
Status: active
Page Count: 2
ICS Code (Steels for pressure purposes): 77.140.30
scope:

This specification2 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 the following grades:

Grade B 11: 1.25 % chromium, 0.55 % molybdenum

Grade B 22: 2.25 % chromium, 1.00 % molybdenum

The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.

2 For ASME Boiler and Pressure Vessel Code applications see related Specification SA-739 in Section II of that code.
