• The letters P, R, S and T in the table indicate the range of tensile strength of quenched and tempered steels.
• If bars are straightened by reeling or cold rectification the surface becomes work-hardened and the specified maximum Brinell hardness to be obtained on such bars shall be agreed between the manufacturer and the purchaser.
