BS EN 10025-6:2019

What is BS EN 10025‑6 about?  

BS EN 10025 is a series of European standards on structural steel that discusses the best procedures and specifications required for manufacturing high-quality steel and steel products. BS EN 10025‑6 is the sixth part of a series of documents on structural steel. BS EN 10025‑6 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 apply 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. 

Who is BS EN 10025‑6 for?  

BS EN 10025‑6 on hot rolled products of structural steels is relevant to: 

• Steel manufacturers 
• Testing and assessment facilities 
• Mechanical engineer  

Why should you use BS EN 10025‑6? 

High yield steels are designed to provide exceptional strength values after heat treatment and mechanical profiling. Due to the material’s high yield, it can be used in a variety of load-bearing applications. 

BS EN 10025‑6 provides guidance on the manufacturing process, chemical composition, mechanical properties, impact properties, surface properties, dimensions, tolerances on dimensions, shape, and mass of structural steels. BS EN 10025‑6 specify tests to be carried out for inspection steel which helps you to maintain the quality of steel. BS EN 10025‑6 exemplifies the required mechanical property and chemical property that helps you achieve precision in terms of product functionality. 

As a user of BS EN 10025‑6, you can be ensured of all the properties of high yield strength alloy steels. With obedience and compliance to BS EN 10025‑6, you can efficiently manufacture high-quality high yield strength structural steels. BS EN 10025‑6 helps you to build consumer trust and confidence in the product. With BS EN 10025‑6 you can be ensured that the products consistently meet and exceed quality assurance targets.

What’s changed since the last update?  

BS EN 10025‑6:2019 supersedes BS EN 10025‑6:2004+A1:2009, which is withdrawn. 

The main changes concerning the previous edition are listed below: 

• Part 6 is now a stand-alone standard for technical delivery conditions including the preparation of samples and test pieces, the test methods, the marking, labeling and packaging, and the drawings 
• For applications under the CPR this document and part 1 are used together 
• Requirements for elements not defined were added to 7.2.1 and 7.2.2 
• Option 33 was added, option 3 was renumbered to option 24, and option 9 was deleted 
• Si-content in 7.2.4 was changed, 7.4.3 concerning hot-dip zinc coating was modified 
• In tables 3 and 4 the values were extended for thicknesses up to 200 mm, references were updated and document editorial revised
