Part 6 of BS EN 10025-6:2004+A1:2009, in addition to part 1, specifies requirements for flat products of high yield strength alloy special steels. The grades and qualities are given in Tables 2 to 4 (chemical composition) and Tables 5 to 7 (mechanical properties) and are supplied in the quenched and tempered condition as given in 6.3.

The steels specified in BS EN 10025-6:2004+A1:2009 are applicable to hot-rolled flat products with a minimum nominal thickness of 3 mm and a maximum nominal thickness less than or equal to 150 mm for grades S460, S500, S550, S620 and S690, a maximum nominal thickness less than or equal to100 mm for grade S890 and a maximum nominal thickness less than or equal to 50 mm for grade S960, in steels which, after quenching and tempering, have a specified minimum yield strength of 460 MPa1) to 960 MPa1).
