ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete ashm up to date. The steelmaking processes are not all intended for the same purpose, but will improve the through-thickness ductility to various degrees depending on the process used.

Promoting, selling, recruiting, coursework and thesis posting is forbidden. Reduction of Area Requirements S3. This specification covers procedures and acceptance standards for the determination of reduction of area using steel plates as tension test specimen.

Two tests shall be required from each quenchedand-tempered plate. A superscript epsilon e indicates an editorial change since the last revision or reapproval.

This standard is subject to revision at any time by the responsible technical committee and must be reviewed every? Combining values from the two systems may result in nonconformance with the specification. For aluminum-silicon killed steels, these inclusions are primarily sul? The number of tests required will depend upon the thickness of the plate being tested and the reduced section length selected. The potential variability of the test results also increases the possibility that subsequent testing of a steel plate quali?
