The heat or cast analysis shall conform to that specified requirement. However, unless the order specifies the applicable “M” specification designation SI unitsthe material shall be furnished to inch-pound units. Full hard can be produced with either a pearlitic or spheroidized microstructure or a mixture of both.

For accuracy in testing, the hardness scales should not overlap. 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.

The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. It is normally produced to give the lowest maximum Rockwell hardness for each grade.

OD maxNo. It is produced to specified Rockwell hardness ranges, the maximum being higher than obtained for the annealed type.

It is furnished in the following types as specified:.

Standard Specification for Steel, Strip, High-Carbon, Cold-Rolled

The values listed are not exact conversions of the values listed in the inch-pound tables but instead are rounded or rationalized values. It is produced to minimum Rockwell hardness requirements, which vary with grade, microstructure and gage. This abstract is a brief summary of the referenced standard. Full hard can be produced with either a pearlitic or spheroidized microstructure or a mixture of both.
