SIST EN 2817:2010 is the Slovenian standard identical to EN 2817:2009 for aerospace steel bar stock. Published by SIST, it specifies the requirements for steel FE-PM1802 (X5CrNiCu15-5), consumable electrode remelted, solution treated and precipitation treated, supplied as bar for machining for aerospace applications. Manufacturers, test laboratories and purchasers use it to agree the material condition, property checks and acceptance criteria.

What does SIST EN 2817:2010 specify?

SIST EN 2817:2010 specifies one aerospace steel product by material designation, melting route, heat treatment state, form and size limit. The standard is organized through numbered clauses that cover scope, normative references, chemistry, melting, delivery condition, mechanical and metallurgical characteristics, inspection, marking and product qualification.

For practical use, the document tells a supplier what bar stock may be supplied, what condition it must be in, and what tests and checks are used before acceptance for machining.

What are the key requirements of SIST EN 2817:2010?

SIST EN 2817:2010 fixes the product as bar for machining in the alloy FE-PM1802 (X5CrNiCu15-5) and limits it to the stated size range a or D ≤ 200 mm. That matters because the requirements are written for this product form, not for plate, forging or other wrought products.

Composition and melting

The standard gives chemical composition limits for the alloy and requires consumable electrode remelting. In practice, this is the starting point for melt control, supplier certification and incoming chemical verification.

Delivery condition and heat treatment

SIST EN 2817:2010 defines delivery conditions and the associated heat treatment routes for the supplied bar. This matters because the ordered condition affects strength, ductility and machinability, so the purchase order and inspection records need to match the delivered state.

Mechanical performance

The requirements matrix covers proof stress, tensile strength, elongation, reduction of area, hardness and impact strength. The required property set varies with section size and test direction, so the test plan has to follow the correct row of the table rather than using one generic acceptance rule.

Metallurgical quality and defects

SIST EN 2817:2010 also controls microstructure, δ ferrite content, grain size, external defects, cleanliness or inclusion content, macrostructure and internal defects. These checks matter in aerospace because hidden defects or out-of-family structure can affect machining behavior and finished-part reliability.

Inspection, marking and qualification

The standard includes marking inspection and dimensional inspection, and it links product qualification to EN 2043. Clause 100 says the qualification programme is to be agreed between manufacturer and purchaser, which makes the acceptance plan part of the contract.

What terms does SIST EN 2817:2010 define?

• FE-PM1802 (X5CrNiCu15-5) - the material designation for the steel covered by the standard.
• Consumable electrode remelted - the melting route required for this steel.
• Solution treated - the heat-treated supply condition used in the standard.
• Precipitation treated - the additional heat treatment used to reach the strengthened condition.
• Rm - the tensile strength symbol used in the property requirements.
• Rp0,2 - the proof stress symbol used in the mechanical property table.
• δ ferrite - the ferrite phase whose content is checked as part of microstructure control.

Who uses SIST EN 2817:2010?

SIST EN 2817:2010 is used by aerospace material suppliers, heat treaters, machinists, quality managers, test laboratories and purchasers. They use it to specify the bar condition, verify chemistry and heat treatment, check properties, and accept material before machining into aerospace parts.

What changed in SIST EN 2817:2010 from the previous edition?

SIST EN 2817:2010 is identified as identical to EN 2817:2009.

Which standards are used with SIST EN 2817:2010?

Standard	What it contributes
EN 2043	General requirements for semi-finished product qualification, excluding forgings and castings.
EN 4258	General organization of aerospace metallic material standards and the links between EN standard types and their use.
EN 4436	Test method for determining δ ferrite content.
EN 4500-5	Rules for drafting and presenting steel material standards.
EN 4700-002	Technical specification for wrought bar and section products.

What does the SIST EN 2817:2010 document contain?

The document contains a chemical composition table, heat-treatment and delivery-condition requirements, and a property matrix that links section size and test direction to mechanical performance. It also sets out metallurgical checks for microstructure, δ ferrite content, grain size, inclusions, macrostructure and internal defects.

For acceptance, it also points to marking inspection and dimensional inspection, and it uses EN 4700-2 for several of the test and inspection methods. In practice, the document functions as a specification for ordering, qualification and receiving aerospace machining bar.
