Overview
EN 10250-4:2021 - Open die steel forgings for general engineering purposes (Part 4: Stainless steels) is a CEN European Standard that defines the technical delivery requirements for open-die forgings, forged bars and products pre-forged or finished in ring-rolling mills manufactured from stainless steels. It covers stainless grades with ferritic, martensitic, austenitic and austenitic‑ferritic (duplex) microstructures and provides requirements for chemical composition, corrosion characteristics, heat treatment and mechanical properties.
Key topics and technical requirements
- Scope and product types: Applies to open die forgings, forged bars and ring-rolled products made from stainless steels for general engineering use.
- Chemical composition: Cast analysis and product analysis requirements are given in tabulated form (Tables 1–3), with permissible deviations between cast and product analysis specified (Table 4). Intentional additions of elements not listed require purchaser agreement.
- Corrosion resistance: Resistance to intergranular corrosion for austenitic, austenitic‑ferritic and ferritic grades is addressed by reference to EN ISO 3651-2; note that EN ISO 3651-2 is not applicable to martensitic and precipitation‑hardening steels.
- Heat treatment: Guidance for heat treatment conditions is provided in Annex A (Tables A.1–A.3). Grain size is at manufacturer’s discretion. If post‑heat‑treatment straightening is performed, procedures must avoid harmful residual stresses; thermal stress relief applied to forgings must also be applied to test specimens.
- Mechanical properties: Room temperature mechanical properties and testing requirements are in Tables 5–7; low temperature properties are shown in Annex B. Elevated temperature proof strength references are given to EN 10088‑3.
- Testing and delivery: Test-piece preparation, sampling and test methods are aligned with EN 10250‑1 requirements and relevant normative references.
Practical applications
- Specification benchmark for manufacturers and purchasers when ordering stainless steel forgings for pumps, valves, shafts, rings and general engineering components.
- Basis for quality control, inspection and acceptance testing of forged stainless steel components used in chemical, petrochemical, power generation and marine industries.
- Reference for material selection where corrosion resistance, mechanical performance at room and low temperature, and heat‑treatability are critical.
Who uses this standard
- Forging manufacturers, heat‑treaters and ring‑rolling mills
- Design and procurement engineers specifying forged stainless components
- Quality assurance, inspection and testing laboratories
- Project managers and fabricators in oil & gas, chemical processing, power and marine sectors

4 Chemical composition
4.1 Cast analysis
The chemical composition of the steel shall be determined by cast analysis and shall conform to the
analysis given in Tables 1, 2 and 3 (see A.7, A.8, and A.11 of EN 10250-1:1999).
Elements not quoted in Tables 1, 2, and 3 shall not be added intentionally to the steel without the
agreement of the purchaser, except for the purpose of finishing the heat. All reasonable measures
should also be taken to prevent the addition from the scrap, or other material used in the manufacture
of the steel, of such elements which affect the corrosion resistance, mechanical properties and
applicability of the steel.
4.2 Product analysis
The product analysis shall not deviate from the specified cast analysis (see Tables 1, 2 and 3) by more
than the values specified in Table 4 (see 9.2 of EN 10250-1:1999).
4.3 Chemical corrosion properties
Referring to resistance to intergranular corrosion as defined in EN ISO 3651-2, for austenitic, austenitic-
ferritic and ferritic stainless steels the specifications in Tables 6 and 7 apply.
NOTE 1 EN ISO 3651-2 is not applicable for testing martensitic and precipitation hardening steels.
NOTE 2 The corrosion resistance of stainless steels is very dependent on the type of environment and can
therefore not always be clearly ascertained through laboratory tests. It is therefore advisable to draw on the
available experience of the use of the steels.
