Steel die forgings - Tolerances on dimensions - Part 2: Upset forging made on horizontal forging machines
1.1 This European Standard specifies the dimensional tolerances for steel upset forgings made on horizontal forging machines. The second part of this European Standard applies to hot upset forgings, in the delivery condition, made in carbon and alloy steels. The tolerances specified apply to forgings not exceeding 250 kg in mass or 2 500 mm maximum dimension. Tolerances for heavier or layer forgings are subjected to negociation.
Gesenkschmiedeteile - Maßtoleranzen - Teil 2: Warm hergestellt in Waagerecht-Stauchmaschinen
Diese Europäische Norm legt die Maßtoleranzen für Gesenkschmiedeteile aus Stahl, hergestellt auf Waagerecht-Stauchmaschinen, fest. Der zweite Teil dieser Europäischen Norm gilt für warm-gestauchte Schmiedeteile im Lieferzustand, hergestellt aus Kohlenstoff- und legiertem Stahl. Die angegebenen Toleranzen gelten für Schmiedeteile, die 250 kg Masse oder 2.500 mm max. Abmessung nicht überschreiten. Toleranzen für schwere oder größere Schmiedeteile sind Verhandlungssache.
Pièces forgées par estampage en acier - Tolérances dimensionelles - Partie 2: Pièces exécutées à chaud sur machines horizontales à forger
1.1 La présente norme européenne spécifie les tolérances dimensionnelles des pièces en acier exécutées par refoulement à chaud sur machines horizontales à forger. Cette seconde partie de la présente norme européenne s'applique aux pièces en acier au carbone et en acier allié, dans leur état de livraison, exécutées par refoulement à chaud. Les tolérances indiquées sont applicables aux pièces estampées dont la masse n'excède pas 250 kg ou dont la dimension la plus grande n'excède pas 2 500 mm. Les tolérances des pièces estampées plus lourdes ou plus largement dimensionnées doivent faire l'objet d'un accord particulier.

Overview
EN 10243-2:1999 - Steel die forgings: Tolerances on dimensions - Part 2 specifies dimensional tolerances for steel upset forgings produced on horizontal forging machines. Published by CEN, this part covers hot upset forgings in the delivery condition, made from carbon and alloy steels. The tolerances apply to forgings with a mass up to 250 kg or a maximum dimension of 2 500 mm; tolerances for heavier or layered forgings are subject to negotiation between supplier and purchaser.
Key topics and requirements
- Scope and applicability: Defines the range of forgings covered (hot upset forgings on horizontal machines) and material groups (carbon and alloy steels).
- Dimensional tolerances: Sets the method for applying tolerance classes to upset forgings in the delivery condition (note: specific numerical tolerance values are provided in the full standard).
- Size and mass limits: Applies to forgings ≤ 250 kg or ≤ 2 500 mm overall dimension; exceptions and special cases are handled by agreement.
- Delivery condition focus: Tolerances refer to the finished product as supplied, not to intermediate or heat-treated states.
- Negotiation for non-standard items: Provides a basis for contractual negotiation where forgings exceed the standard size/mass limits or for unusual manufacturing methods (e.g., layer forgings).
Practical applications
EN 10243-2 is used to ensure consistent dimensional quality for hot upset forgings produced on horizontal forging presses. Typical applications include:
- Manufacturing and quality control of forgings for automotive, construction, agricultural machinery, valves and fittings, and general engineering.
- Procurement and contract specifications where buyers require standardized forging tolerances for carbon and alloy steel parts.
- Inspection and acceptance testing: quality engineers and inspectors use the standard to verify conformance of delivered upset forgings.
- Product design: designers reference the standard to establish realistic dimensional allowances and reduce costly rework.
Who should use this standard
- Forging manufacturers and foundries working with upset forging on horizontal machines
- Quality assurance and metrology teams specifying and checking dimensional tolerances
- Purchasing and procurement professionals writing supply contracts for steel forgings
- Design engineers specifying tolerances for mechanical and structural components
