Applicability and limitations

China Steel bar and wire-rod catalogue CAT.NO.3-BD-01-2014-C1, PDF page 28

printed page 26, 7.1.24 ASTM A36 (edition not stated). The original catalogue does not explicitly identify the analysis type for this table. Historical manufacturer range data, not guaranteed standard limits or heat-specific measurements; this does not establish supply by Creation Group. Condition: C/Mn must be selected for the diameter condition; without a selection, the entire table range must not be assumed; Cu may be ≥0.20% when required; Cu is not automatically added.

Composition conditions

Historical manufacturer 2014-C1 catalogue, bars/wire rod; Where the referenced standard edition is not identified, a year is not borrowed from another catalogue; a catalogue is not upgraded to the official standard text.
A dash or blank must not be treated as zero. Composition data do not establish completeness or applicability of a formula; mechanical properties and supply require separate verification.
C/Mn must be selected by diameter condition; without selection, the entire table range must not be assumed; Cu may be ≥0.20% when required; Cu is not automatically added.
Optional condition, steel diameter mm: d ≤20; Steel diameter mm: 20 <d ≤40; Steel diameter mm: 40 <d ≤100; Steel diameter mm: 100 <d
