ID by 40 in. It is normally produced to give the lowest maximum Rockwell hardness for each grade.
This specification covers the general requirements for cold-rolled carbon spring steel strip in coils or cut lengths. Historical Version s – view previous versions of standard. It is normally produced to give the lowest maximum Rockwell hardness for each grade.
Stay on Astn Continue a6844 Compass. It is furnished in the following types as specified:. Combining values from the two system may result in non-conformance with the standard.
If the minimum temper is over Rockwell C 20 15N Note 1—The term weight is used when inch-pound units are the standard. It is produced to specified Rockwell hardness ranges, the maximum being higher than obtained for the annealed type. The maximum of the specified carbon range is over 0. This standard has been approved for use by agencies of the Department of Defense. This abstract is a brief a864 of the referenced standard. Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend.
For accuracy in testing, the hardness scales should not overlap.
However, under SI the preferred term is mass. OD maxNo. 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 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.
Refer to Table 1 for appropriate scale testing requirements. It is furnished in the following types as specified: Link to Active This link will always route to the current Active version of the standard.
It is produced to a maximum Rockwell hardness. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Strip is classified as product that is 0. The edges of the bend test specimens shall be rounded and free of burrs;? Referenced Documents purchase separately The documents listed below are referenced within astn subject asrm but are not provided as part of the standard.
It is produced to minimum Rockwell hardness requirements, which vary with grade, microstructure and gage. Hardness test and bend test shall be made to conform to the requirements specified. It is produced to a maximum Rockwell hardness. Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM Atm.

The values stated in each system are not exact equivalents; therefore, each system must be used independently of the other. Any visible cracking on the tension side of the bend portion shall be cause for rejection.
It is furnished in the following types as specified:. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. It is produced to minimum Rockwell hardness requirements, which vary with grade, microstructure and gauge. The values stated in each astk may not be exact equivalents; therefore, each system shall be used independently of the other. Where material is to be bent in fabricating operations a more liberal bend radius may be required and should be based on prior experience or consultation with the steel producer, or both.
The minimum hardness should be established between the consumer and the producer.
