General Information

Overview
EN 10263-3:2017 (CEN) specifies the technical delivery conditions for case hardening steels supplied as round rod, round bars and wire for cold heading and cold extrusion. It applies to non‑alloy and alloy steels with a diameter up to and including 100 mm and is part of the EN 10263 series. EN 10263-1:2017 (General technical delivery conditions) is indispensable when applying this Part.
Key topics and requirements
- Scope and product forms: round rod, round bars and wire (≤100 mm) intended for cold heading/cold extrusion and subsequent case hardening.
- Classification and designation: steels are classified as special steels (EN 10020); Part 3 lists both non‑alloy and alloy case‑hardening grades.
- Chemical composition: cast (heat) analysis ranges and permissible product‑analysis deviations are defined in tabulated form - agreed limits must be met at delivery.
- Mechanical properties: tensile and hardness requirements are specified for delivery conditions; test methods and applicable tables are referenced.
- Hardenability: Jominy (end‑quench) test requirements and scatter‑band options are provided. Hardenability suffixes +H, +HH, +HL denote standard and restricted hardenability bands.
- Delivery and heat‑treatment conditions: symbols for delivery conditions (e.g. +U, +AC, +FP) and combinations of product form / heat treatment are defined.
- Surface condition: standard surface states and options (rolled +AR, cold drawn +C, skin passed +LC, peeled +PE) and special surface requirements by agreement.
- Supplementary requirements: additional or special requirements (e.g. specific silicon ranges, aluminium additions for heading) may be agreed at order; EN 10263-1 annex describes options.
Applications and users
Who uses EN 10263-3:2017:
- Steel mills and rod/bar manufacturers for specifying production, deoxidation and chemical ranges.
- Cold heading and cold extrusion component producers (fasteners, pins, shafts).
- Heat‑treatment shops specifying case carburizing/carbonitriding and hardenability targets.
- Quality engineers, procurement and standards specialists writing material specifications or purchasing orders.
Typical applications:
- Parts needing a hard wear‑resistant surface with a tough ductile core (gears, shafts, pins, high‑strength fasteners and headed components produced by cold forming followed by case hardening).
Related standards
- EN 10263-1:2017 - General technical delivery conditions (indispensable).
- EN 10020 - Definition and classification of grades of steel.
- Relevant test standards for Jominy, tensile and hardness testing as referenced in EN 10263-1.
EN 10263-3:2017 helps ensure material consistency, traceable chemistry and predictable hardenability for reliable cold‑formed, case‑hardened components in industrial applications.
