Organization: ASTM International
Publication Date: 1 December 2016
Status: inactive
Page Count: 48
ICS Code (Steel bars and rods): 77.140.60
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 Tables 1 and 2. Special hardenability limits are also permissible when approved by the purchaser and manufacturer.

(A) New designations established in accordance with Practice E527 and SAE J 1086, Recommended Practice for Numbering Metals and Alloys (UNS).(B) Sulfur content range is 0.035 to 0.050 %.(C) These steels can be expected to have a 0.0005 % min boron content.(D) Vanadium content range is 0.10 to 0.15 %.(E) Minimum vanadium content is 0.15 %. (A) Standard H Steels can be produced with a lead range of 0.15-0.35 %. Such steels are identified by inserting the letter "L" between the second and third numerals of the grade designation, for example, 15L22 H. Lead is generally reported as a range of 0.15-0.35 %.(B) New designations established in accordance with Practice E527 and SAE J 1086, Recommended Practice for Numbering Metals and Alloys (UNS).(C) These steels can be expected to have 0.0005 % min boron content.

1.3 The values stated in inch-pound units are to be regarded as standard. No other units of measurement are included in this standard.
