Historical Standard: ASTM A304-05 Standard Specification for Carbon and Alloy Steel Bars Subject to End-Quench Hardenability Requirements
SUPERSEDED (see Active link, below)
ASTM A304
1. Scope
1.1 This specification covers hot-worked alloy, carbon, and carbon-boron steels in a variety of compositions and sizes, which may attain specified depth of hardening in the end quench test. These steel compositions are identified by the suffix letter 'H' added to the conventional grade number.
1.2 This specification provides for analyses other than those listed under . Special hardenability limits are also permissible when approved by the purchaser and manufacturer.
1.3 The values stated in inch-pound units are to be regarded as the standard.
2. Referenced Documents (purchase separately) The documents listed below are referenced within the subject standard but are not provided as part of the standard.
