ASTM A434 - 06 Standard Specification for steel Bars, Alloy, Hot-Wrought or Cold-Finished, Quenched and Tempered
This specification covers hot-wrought and cold-finished quenched and tempered alloy steel bars. The steel materials shall be melt processed by using open-heart, basic oxygen, or electric furnace and shall conform to the austenitic grain size requirement. Tension tests shall be performed wherein the steel specimens shall conform to the required values of yield strength, tensile strength, and elongation.

1. Scope
1.1 This specification covers hot-wrought and cold-finished quenched and tempered alloy steel bars.
1.2 Hot-wrought bars are available in three strength level classes designated BB, BC, and BD, and cold-finished bars in two strength level classes designated BB and BC. The bars are available in the conditions specified in subject to the size limitations shown.
1.3 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.
