Organization: ASTM International
Publication Date: 1 November 2017
Status: active
Page Count: 6
ICS Code (Steel bars and rods): 77.140.60
scope:

1.1 This specification covers hot-wrought special quality carbon steel bars. Special quality bar applications include forging, heat treating, cold drawing, machining, and many structural uses. A guide for the selection of steel bars is contained in Practice A400.

1.2 The bars shall be furnished in the grades specified in Table 1. Sections and sizes of bar steel available are covered in Specification A29/A29M. Hot-wrought special quality carbon steel bars are produced in cut lengths and coils; the manufacturer should be consulted regarding sections and sizes available in coils, produced to a chemical composition.

Rephosphorized and Resulfurized Carbon Steel

(A) New designations established in accordance with Practice E527 and SAE J 1086.(B) Maximum unless otherwise indicated.(C) When silicon is required, the following ranges and limits are commonly specified: 0.10 %, max, 0.10 to 0.20 %, 0.15 to 0.35 %, or 0.20 to 0.40 %.(D) Copper can be specified when required as 0.20 % minimum.(E) When lead is required as an added element to a standard steel, a range of 0.15 to 0.35 % incl is specified. Such a steel is identified by inserting the letter "L" between the second and third numerals of the grade designation, for example, 10 L 45. A cast or heat analysis is not determinable when lead is added to the ladle stream.(F) When boron treatment is specified for killed steels, the steels can be expected to contain 0.0005 to 0.003 % boron.(G) The elements bismuth, calcium, selenium, or tellurium may be added as agreed between purchaser and supplier.(H) It is not common practice to produce these steels to specified limits for silicon because of its adverse effect on machinability.

1.3 Merchant quality hot-wrought carbon steel bars are covered in Specification A575.

1.4 Some end uses may require superior surface quality, or special chemical restrictions, metallurgical characteristics, heat treatment, or surface finishes which the purchaser may obtain by designating one or more of the available Supplementary Requirements.

1.5 The values stated in inch-pound units are to be regarded as standard.

1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
