What is this standard about?
This European standard is the last in a six-part series detailing technical delivery conditions for hot rolled structural steel products. The series is pivotal because it controls the majority of steel-frame-constructed buildings within the EU. This part deals with flat products of high yield strength structural steels in the quenched and tempered condition.
Who is this standard for?
- Steel manufacturers
- Steel importers, stockholders and distributors
- Construction companies
- Provides of testing and assessment facilities
- Design engineers
- Purchasing staff
- Quality engineers
- Quality managers
Why should you use this standard?
It 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.
What’s changed in this update?
This is a revision of BS EN 10025-6:2004+A1:2009, updated to reflect modern construction standards and practices. It is now a stand-alone standard for technical delivery conditions including the preparation of samples and test pieces, the test methods, the marking, labelling and packaging and the drawings. Requirements for elements not defined were added to 7.2.1 and 7.2.2; Section 7.4.3 concerning hot-dip zinc coating was modified and Si-content in 7.2.4/5 was changed. In Tables 3 and 4 the values were extended for thicknesses up to 200 mm.
