BS EN 10025-6:2019 - TC

This standard BS EN 10025-6:2019 - TC Tracked Changes. Hot rolled products of structural steels is classified in these ICS categories:

• 77.140.10 Heat-treatable steels
• 77.140.50 Flat steel products and semi-products
• 91.100.99 Other construction materials

This document specifies technical delivery conditions for flat products of high yield strength alloy special steels. The grades and qualities are given in Tables 1 to 3 (chemical composition) and Tables 4 to 6 (mechanical properties) and are supplied in the quenched and tempered condition. The steels specified in this document are applicable to hot-rolled flat products with a minimum nominal thickness of 3 mm and a maximum nominal thickness of 200 mm for grades S460, S500, S550, S620 and S690, a maximum nominal thickness of 125 mm for grades S890 and S960, in steels which, after quenching and tempering, have a specified minimum yield strength of 460 MPa to 960 MPa.
