Specifies requirements for cold-finished carbon steel and carbon-manganese steel bars manufactured from hot-rolled bars and semifinished products for general engineering purposes.

This Standard specifies requirements for cold-finished carbon steel and carbon-manganese steel bars manufactured from hot-rolled bars and semifinished products (see AS 1442), for general engineering purposes. The Standard applies to steel supplied to specified chemical composition only or to specified chemical composition and mechanical properties. It permits the addition of elements, such as boron, and micro-alloying elements for the achievement of special properties. NOTES: 1 Advice and recommendations on information that should be supplied by the purchaser at the time of enquiry and order are given in Appendix A. 2 Alternative means for determining compliance with this Standard are given in Appendix B.
