Overview
EN 10089:2002 - "Hot-rolled steels for quenched and tempered springs - Technical delivery conditions" is a CEN standard that defines the technical delivery requirements for hot-rolled spring steels supplied as round and flat bars, ribbed/grooved bars and rod. It covers steels intended for hot-formed or cold-formed springs subsequently heat-treated, the permitted heat‑treatment and surface conditions at delivery, and the information and inspection documents that purchasers and suppliers must agree.
Key topics
- Scope & product forms: Requirements apply to alloy spring steels listed in Table 3, supplied in the heat‑treatment conditions of Table 1 and surface conditions of Table 2.
- Mandatory purchaser information: quantity, product form, dimensional standard and tolerances, EN 10089 reference, steel name/number, requested heat‑treatment and surface symbols, and inspection document type (EN 10204).
- Manufacturing & metallurgical rules: steels must be fully killed; cast separation is required; manufacturing routes are at manufacturer’s discretion within specified limits.
- Mechanical and metallurgical requirements: chemical composition, hardness limits, and hardenability (end‑quench/Jominy guidance referenced); options for ordering based on core hardness or restricted hardenability (Tables 5, 7, 8).
- Structure and surface: austenitic grain size requirement (grade 6 or finer), non‑metallic inclusion content (Annex A), acceptable decarburisation depths (Table 9), and prohibition of removing surface discontinuities by welding.
- Shearability and dimensions: guidance on shearability of as‑rolled material (+AR) and requirement to agree tolerances/dimensional standards (Annex C).
- Inspection & documentation: test reports and inspection certificates per EN 10204; optional non‑destructive testing and product analysis arrangements (Annex A).
Applications & users
- Who uses it: steel producers, spring manufacturers, forging shops, heat‑treatment vendors, quality engineers and procurement specialists specifying spring steels in Europe.
- Practical uses: specifying contractual delivery conditions for raw spring steel bars/rod; ensuring compatibility with downstream forming, quenching and tempering processes; defining inspection, hardness/hardenability requirements, and acceptable surface quality for high‑performance springs (automotive, industrial, suspension, valve springs).
Related standards
- EN 10204 (inspection documents)
- EN 10021 (general technical delivery requirements)
- EN 10221 (surface quality classes for hot‑rolled bars and rods)
- EN ISO 642 (Jominy end‑quench hardenability test)
- EN ISO 6506 / 6508 (hardness tests)
EN 10089:2002 is primarily a delivery‑specification standard: use it to ensure material traceability, agreed heat‑treatment/surface conditions and test documentation when procuring hot‑rolled spring steels.
