The heat or cast analysis shall conform to that specified requirement. It is furnished in the following types as specified: Referenced Documents purchase separately The documents listed below are referenced within the subject standard but sstm not provided as part of the standard. The values listed are not exact conversions of the values listed in the inch-pound tables but instead are rounded or rationalized values.

When bend radius for thickness is over 0. B These bend tests apply to the bending performance of test specimens only. If the minimum temper is over Rockwell C a6884 15N Active view a6844 version of standard. Full hard can be produced with either a pearlitic or spheroidized microstructure or a mixture of both.

This specification covers the general requirements for cold-rolled carbon spring steel strip in coils or cut lengths. For accuracy in testing, the hardness scales should not overlap. Strip is classified as product that is 0. A number in parentheses indicates the year of last reapproval.

The maximum of the specified carbon range is over 0. Full hard can be produced with either a pearlitic or spheroidized microstructure or a mixture of both. A Test Methods astmm De?

Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM Headquarters. The strip shall be furnished cold rolled spheroidized annealed, soft annealed, intermediate hardness, or full hard, as specified. It is produced to minimum Rockwell hardness requirements, which vary with grade, microstructure and gauge. The values listed are not exact conversions of the values listed in the inch-pound tables but instead are rounded or rationalized values.

The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Hardness test and bend test shall be made to conform zstm the requirements specified. Full hard can be produced with either a pearlitic or spheroidized microstructure or a mixture of both. It is produced to speci?

It is produced to a maximum Rockwell hardness. 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 asmt, or both. Combining values from the two systems will result in nonconformance with the specification.

The metric portions of the tables herein list permissible variations in dimensions and mass see Note 1 in SI metric units. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other.

It is furnished in the following types as specified:. Full hard can be produced with either a pearlitic or spheroidized microstructure or a mixture of both. Within the text, the SI units are shown in brackets. The minimum hardness should be established between the consumer and the producer.

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

Note 1—The term weight is used when inch-pound units are the standard. Combining values from the two systems may result in non-conformance with the standard. However, under 6a84 the preferred term is mass. The minimum hardness should be established between the consumer and the producer. The values stated in each system are not exact equivalents; therefore, each system must be used independently of the other.

However, under SI the preferred term in mass. 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.
