Specifies requirements for carbon steel and carbon-manganese steel rods, bars, blooms, billets and slabs, delivered in the as-rolled or normalized condition, for forging and for general engineering applications.

This Standard specifies requirements for carbon steel and carbon-manganese steel rods, bars, blooms, billets and slabs, delivered in the as-rolled or normalized condition, for forging and for general engineering purposes. It specifies chemical composition requirements for all grades, and tensile strength requirements for grades required to meet mechanical properties. The Standard permits the addition of boron and micro-alloying elements for the achievement of special properties.The Standard also specifies requirements for the maximum depth of surface imperfections and gives recommended machining allowances for bars of various sizes.NOTES:1 Advice and recommendations on information to be supplied by the purchaser at the time of enquiry or order are contained in Appendix A.2 Alternative means for determining compliance with this Standard are given in Appendix B.
