EN 10083 Standard: Specifications for Quenched and Tempered Steels

Technical Standard EN 10083: Quenched and Tempered Steels

The EN 10083 standard is a fundamental document for the metallurgical industry, defining technical delivery conditions for high-quality steels intended for heat treatment. EV Group China experts ensure the supply of rolled steel that fully complies with these specifications, guaranteeing consistency in mechanical properties and chemical composition.

EN 10083-1: General Technical Delivery Conditions

This part of the international standard establishes unified requirements for the delivery of semi-finished products, long products, and forgings. Key product forms supplied by EV Group China include:

• Hot-rolled billets, slabs, and bars;
• Rod and sheet metal products;
• Forgings and strip steel.

Steels classified under EN 10083-1 are intended for critical mechanical engineering applications. Special attention is paid to quality and special steels, with the latter subject to strict limits on non-metallic inclusion content, phosphorus, and sulfur, as well as standardized hardenability indices according to the Jominy method.

EN 10083-2: Technical Delivery Conditions for Non-Alloy Steels

The standard regulates requirements for non-alloy structural steels subjected to quenching and tempering or induction hardening. The table below presents the main grades available for order at EV Group China:

EN 10083-3: Technical Delivery Conditions for Boron Steels

The EN 10083-3 specification covers alloy steels, including those with boron (B) additions, which are characterized by increased hardenability. These materials are in high demand for the production of load-bearing components in machines and mechanisms.
