Five groups based on mechanical property requirements.

This Part of BS 2772 specifies requirements for wrought steel plates, blooms, billets, slabs, bars, forgings and drop forgings to be used for colliery cage suspension gear, colliery tubs, mine-car drawgear and couplings and rope sockets. Details of information to be supplied by the purchaser are given in Appendix B. Appendix C gives guidance on chemical composition for each of the five groups of steels considered.
