The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other.

NOTE 1—A typical ordering description is as follows: Within the text, the SI units are shown in brackets. It is furnished in the following types as specified:. This abstract is a brief summary of the referenced standard.

Full hard w684 be produced with either a pearlitic or spheroidized microstructure or a mixture of both. A superscript epsilon e indicates an editorial change since the last revision or reapproval.

The values listed are not exact conversions of the values listed in the inch-pound tables but instead are rounded or rationalized values. Combining values from the two systems may result in non-conformance with the standard. It is produced to minimum Rockwell hardness requirements, which vary with grade, microstructure and gage.

Originally published as A — It is produced to specified Rockwell hardness ranges, the maximum being higher than obtained for the annealed type. Active view current version of standard.

ASTM A / AM – 06 Standard Specification for Steel, Strip, High-Carbon, Cold-Rolled

This standard has been approved for use by agencies of the Department of Defense. On either hardness scale, a range of ten points arithmetic difference is required. It is normally produced to give the lowest maximum Rockwell axtm for each grade.

It is normally produced to give the lowest maximum Rockwell hardness for each grade. The minimum hardness should be established between the consumer and the producer.

However, unless the order specifies the applicable “M” specification designation SI unitsthe zstm shall be furnished to inch-pound units.

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

The maximum of the specified carbon range is over 0. It is produced to a maximum Rockwell hardness.

Asmt values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. The maximum of the specified carbon range is over 0. The minimum hardness should be established between the consumer and the producer. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other.

Conformance to SI tolerances is mandatory when the “M” specification is used. Combining values from the two systems will result in nonconformance with the specification. It is furnished in the following types as specified:. It is produced to minimum Rockwell hardness requirements, which vary with grade, microstructure and gauge.

Strip is classified as product that is 0.
