The heat or cast analysis shall conform to that specified requirement. The edges of the bend test specimens shall be rounded and free of burrs;? The metric portions of the tables herein list permissible variations in dimensions and mass see Note 1 in SI metric units.

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 values listed are not exact conversions of the values listed in the inch-pound tables but instead are rounded or rationalized values.

If the maximum temper is aastm Rockwell B 15T93 or 30T82that scale should be used exclusively.

This specification covers the general requirements for cold-rolled carbon spring steel strip in coils or cut lengths.

B These bend tests apply to the bending performance of test specimens only. It is produced to minimum Rockwell hardness requirements, which vary with grade, microstructure and gauge.

Strip is classified as product that is 0. Originally published as A — Your comments will q684 careful consideration at a meeting of the responsible technical committee, which you may attend. The minimum hardness should be established between the consumer and the producer.

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

Full hard can be produced with either a pearlitic or spheroidized microstructure or a mixture of both. Finish and Edges 9. This standard has been approved for use by agencies of the Department of Defense. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. The minimum hardness should be established between the consumer and the producer. It is produced to minimum Rockwell hardness requirements, which vary with grade, microstructure and gage.

The maximum of the specified carbon range is over 0. It is normally produced to give the lowest maximum Rockwell hardness for each grade. However, under SI the preferred term in mass. It is produced to a maximum Rockwell hardness. 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 stated in each system are not exact equivalents; therefore, each system must be used independently of the other.

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.
