EN 10083-3 1.7182 Introduce
The European standard EN 10083-3, Steel – Part 3: Technical Delivery Conditions for Alloy Steels, was adopted in 2018 to set out a range of requirements for the use of alloy steels for engineering purposes in Europe. With the increasing global demand for steel, particularly for specialty steels found in the automotive industry, EN 10083-3 was created to ensure consistent quality standards across different manufacturers.
