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

Strip is classified as product that is 0. The minimum hardness should be established between the consumer and the producer. B These bend tests apply to the bending performance of test specimens only. It is normally produced to give the lowest maximum Rockwell hardness for each grade. The term weight is used when inch-pound units are the standard.

A superscript epsilon e indicates an editorial change since the last revision or reapproval. It is produced to minimum Rockwell hardness requirements, which vary with grade, microstructure and gauge. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application.

The minimum hardness should be established between the consumer and the producer. It is furnished in the following types as specified: If the maximum temper is under Rockwell B 15T93 or 30T82that scale astn be used exclusively.

It is produced to minimum Rockwell aztm requirements, which vary with grade, microstructure and gauge. Combining values from the two systems will result in nonconformance with the specification.

Ast, Version s – view previous versions of standard. Combining values from the two systems may result in non-conformance with the standard. On either hardness scale, a range of ten points arithmetic difference is required.

Hardness test and bend test shall be made to sstm to the requirements specified. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. OD maxNo. NOTE 1—A typical ordering description is as follows: Full hard can be produced with either a pearlitic or spheroidized microstructure or a mixture of both.

It is produced to minimum Rockwell hardness requirements, which vary with grade, microstructure and gage.

The metric portions of the tables herein list permissible ashm in dimensions and mass see Note 1 in SI metric units. It is produced to specified Rockwell hardness ranges, the maximum being higher than obtained for the annealed type. This abstract is a brief summary of the referenced standard.

Note 1—The term weight is used when inch-pound units are the standard. However, unless the order specifies the applicable “M” specification designation SI unitsthe material shall be furnished to inch-pound units.

Your comments are invited either for revision of this standard q684 for additional standards and should be addressed to ASTM Headquarters. Strip is classified as product that is 0. It is less suitable that No.

These ratios apply to bending performance of the test specimen. Combining values from the two systems may result in non-conformance with the standard. Asrm bend radius for thickness is over 0. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other.
