It is produced to a maximum Rockwell hardness. A number in parentheses indicates the year of last reapproval. Refer to Table 1 for appropriate scale testing requirements. Full hard can be produced with either a pearlitic or spheroidized microstructure or a mixture of both. This specification covers cold-rolled, high-carbon strip.

Active view current version of standard. The values listed are not exact conversions of the values listed in the inch-pound tables but instead are rounded or rationalized values.

The maximum of the specified carbon range is over 0. It is normally produced to give the lowest maximum Rockwell hardness for each grade. This abstract is a brief summary of the referenced standard.

Combining values from the two systems may result in non-conformance with the standard. Strip is classified as product that is 0.

It is produced to speci? Hardness test and bend test shall be made to conform to the requirements specified.

It is produced to minimum Rockwell hardness requirements, which vary with grade, microstructure and gage. Link to Active This link will always route to the current Active version of the standard.

Originally published as A — It is furnished in the following types as specified:. However, unless the order specifies the applicable “M” specification designation Zstm unitsthe material shall be furnished to inch-pound units.

It is furnished in the following types as specified:. Strip is classified as product that is 0. Link to Active This link will always route to the current Active version of the standard.

The values stated in each system may not be exact equivalents; therefore, each system shall satm used independently of the other. However, under SI the preferred term is mass. The minimum hardness should be established between the consumer and the producer.
