This specification covers M-grade hot-wrought merchant quality carbon steel bars produced to a chemical composition. Merchant quality bars are used for structural and similar miscellaneous bar applications involving moderate cold bending, moderate hot forming, punching, and welding as used in the production of noncritical parts. Moderate cold bending involves generous bend radius with the axis of the bend transverse to the direction of rolling. Heat analysis shall conform to the requirements as to chemical composition.

This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.

1. Scope

1.1 This specification covers hot-wrought merchant quality carbon steel bars produced to a chemical composition. Merchant quality bars are used for structural and similar miscellaneous bar applications involving moderate cold bending, moderate hot forming, punching, and welding as used in the production of noncritical parts. Moderate cold bending involves a generous bend radius with the axis of the bend transverse to the direction of rolling.

1.2 Special quality hot-wrought carbon steel bars are covered in Specification A 576.

1.3 Some end uses may require one or more of the available designations shown under Supplementary Requirements.

1.4 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.
