This abstract is a brief summary of the referenced standard.

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

It is less suitable that No. The metric portions of the tables herein list permissible variations in dimensions and mass see Note 1 in SI metric units.

Stay on Page Continue to Compass. For accuracy in testing, the hardness scales should not overlap. Within the text, the SI units are shown in brackets. It is produced to a maximum Rockwell hardness. Current edition approved Aa684. This specification covers the general requirements for cold-rolled carbon spring steel strip in coils or cut lengths.

It is produced to specified Rockwell hardness ranges, the maximum being higher than obtained for the annealed type. Active view current version of standard. The metric portions of the tables herein list permissible variations in dimensions and mass see Note 1 in SI metric units. It is furnished in the following types as specified: Historical Version s – view previous versions of standard.

Any visible cracking on the tension side of the bend portion shall be cause for rejection. However, under SI the preferred term in mass. It is produced to minimum Rockwell hardness requirements, which vary with aztm, microstructure and gauge. 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 normally produced to give the lowest maximum Rockwell hardness for each grade.

The edges of the bend test specimens shall be rounded and free of burrs;? It is produced to minimum Rockwell hardness requirements, which vary with grade, microstructure and gage.

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

Hardness test and bend test asgm be made to conform 6a84 the requirements specified. It is produced to a maximum Rockwell hardness. 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. However, under SI the preferred term is mass. Combining values from the two systems may result in non-conformance with the standard.

The values stated in each system are not exact equivalents; therefore, each system must be used independently of the other. The values listed are not exact conversions of the values listed in the inch-pound tables but instead are rounded or rationalized values.
