The minimum hardness should be established between the consumer and the producer. However, unless the order specifies the applicable “M” specification designation SI unitsthe material shall be furnished to inch-pound units. It is produced to specified Rockwell hardness ranges, the maximum being higher than obtained for the annealed type.

Combining values from the two systems may result in non-conformance with the standard. The term weight is used when inch-pound units are the standard.

The maximum hardness limit and the corresponding minimum shall be speci? It is produced to minimum Rockwell hardness requirements, which vary with grade, microstructure and gage.

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

ASTM A / AM – 17 Standard Specification for Steel, Strip, High-Carbon, Cold-Rolled

Note 1—The term weight is used when inch-pound units are the standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other.

This specification covers cold-rolled, high-carbon strip.

Strip is classified as product that is 0. The values listed are not exact conversions of the values listed in the inch-pound tables but instead are asym or rationalized values. The metric portions of the tables herein list permissible variations in dimensions and mass see Note 1 in SI metric units.

Within the text, the SI units are shown in brackets. The heat or cast analysis shall conform to that specified requirement.

Conformance to SI tolerances is mandatory when the “M” specification is used. This abstract is a brief summary of the referenced standard. It is normally produced to give the lowest maximum Rockwell hardness for each grade. B These bend tests apply to the bending performance of test specimens only. It is furnished in the following types as specified:. The maximum of the specified carbon range is over 0.
