What is this standard about?

This European standard is the second 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 non-alloy structural steels.

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 the technical delivery conditions for flat and long products as well as semi-finished products meant for further processing to flat and long products of hot rolled non-alloy quality steels in the grades and qualities given in Tables 1 to 5 (chemical composition) and Tables 6 to 8 (mechanical properties) in the usual delivery conditions as given in 6.3.

Three engineering steels are also specified in this document (see Tables 2 and 4) (chemical composition) and Table 7 (mechanical properties). This document does not apply to structural hollow sections (see BS EN 10210-1 and BS EN 10219-1) and tubes.

The technical delivery conditions apply to:

- Thicknesses = 3 mm and = 150 mm for long products of steel grade S460JR, J0, J2, K2 and S500J0

- Thicknesses = 400 mm for flat products of qualities JR, J0, J2 and K2

- Thicknesses = 250 mm for flat and long products of all other grades and qualities

The steels specified in this document are not intended to be heat treated except products delivered in the delivery condition +N. Stress relieving is accepted. Products delivered in +N condition can be hot formed and/or normalized after delivery (see Clause 3).

This document foresees that semi-finished products which are to be converted to rolled finished products conforming to this document are the subject of special agreements at the time of the order.

The chemical compositions are also agreed to at the time of the order; the values are within the limits of Tables 1 and 2.

For certain grades and product forms suitability for particular applications are specified at the time of the order (see 7.4.2, 7.4.3 and Table 9).

 

What’s changed in this update?

This is a revision of BS EN 10025-2:2004, 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. Option 33 was added, Options 9 and 21 were deleted.

 

This standard BS EN 10025-2:2019 Hot rolled products of structural steels is classified in these ICS categories:

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