(Main)Heat resistant steel castings
- Abstract
This European Standard applies to heat resistant steel castings, for general purposes (non pressure) above 600°C. It applies also to heat resistant nickel and cobalt base alloys. This standard relates to castings manufactured from ferritic, austenitic-ferritic, austenitic steels, nickel and cobalt base alloys (characterised by their chemical composition (see table 1) and mechanical properties (see table 2)). In cases where castings are joined by welding by the founder, this European Standard applies.

SIST EN 10295:2003 is the Slovenian adoption of EN 10295:2002 from SIST/CEN for heat resistant steel castings. It specifies material, manufacture, testing and delivery requirements for castings used for general, non-pressure service above 600 °C, including ferritic, austenitic-ferritic, austenitic, nickel-base and cobalt-base grades.
What does SIST EN 10295:2003 specify?
SIST EN 10295:2003 covers heat resistant steel castings for general purposes above 600 °C and also covers heat resistant nickel and cobalt base alloys. The standard is meant for castings defined by chemical composition and mechanical properties, and it also applies when the founder welds the castings.
The scope excludes welded joints to wrought products such as plates, tubes and forgings, and it excludes welding done by non-founders. In practice, that means the document is for foundry-made castings and not for assemblies where the weld joining method falls outside the founder's control.
The document is organized into 12 clauses and 4 informative annexes:
| Annex | What it covers |
|---|---|
| Annex A | Welding conditions |
| Annex B | Creep properties |
| Annex C | Maximum use temperatures |
| Annex D | Physical properties |
The main clauses cover scope, normative references, terms and definitions, purchaser information, designations, manufacture, requirements, testing and documents on material testing, marking, packaging and surface protection, complaints, and supplementary information.
What are the key requirements of SIST EN 10295:2003?
SIST EN 10295:2003 ties the material specification to the cast analysis in Table 1 and the mechanical properties in Table 2. For buyers and foundries, this is the core of the standard: the grade is identified by chemistry, then checked against the required properties.
Material composition and grade control
The chemical composition of the cast analysis shall comply with Table 1, and any elements not listed there shall not be added intentionally unless the purchaser agrees. Table 3 gives the maximum permitted contents for unspecified elements. In practice, this means the heat must be controlled to the declared grade, and trace additions need agreement.
Mechanical properties and heat treatment
Table 2 gives the mechanical properties at room temperature, and the standard says these values are determined either by hardness testing or by tensile testing, depending on the grade. For ferritic grades, the heat treatment in Table 2 applies unless otherwise agreed; for non-ferritic grades, the stated values correspond to the as-cast condition. This matters because the delivery condition is part of the property definition, not just the alloy name.
Elevated-temperature performance
For use at elevated temperatures, Table B.1 gives creep stress values, including rupture stress and stress for 1 % elongation over long periods. Annex B is informative, so it helps with design and selection rather than acting as the main acceptance table. Annex C gives maximum use temperatures in air, which helps users match the grade to the intended service temperature.
Welding and further processing
Clause 6 allows alternative melting processes at the manufacturer's discretion and permits production welding unless otherwise agreed. Annex A gives welding conditions and post-weld treatments for information, including preheat ranges and stress relief or furnace cooling for listed grades. In practice, a foundry can weld certain castings, but it must control preheat and post-weld treatment when the part design requires it.
Inspection and testing
Clause 8 lists the test methods and marks several as not applicable, including impact testing, ferrite content testing and intergranular corrosion testing. It requires room-temperature tensile testing, allows elevated-temperature tensile testing by agreement, and includes hardness and homogeneity testing. For a buyer, this clause tells you which verification routes are expected and which need to be ordered separately.
What terms does SIST EN 10295:2003 define?
SIST EN 10295:2003 uses the terms and definitions from EN 1559-1:1997 and EN 1559-2:2000. The following terms are central to reading the standard:
- Cast analysis - the chemical composition measured on the casting heat and used in Table 1.
- Check analysis - the verification analysis used to compare the supplied material with the specified cast analysis.
- 0,2 % proof strength (Rp0,2) - the room-temperature yield strength value used for some grades.
- HB - the hardness value used in Table 2 for grades controlled by hardness.
- Creep stress - the stress values in Annex B used for long-term high-temperature design.
- Stress relief annealing - a post-weld heat treatment used in Annex A for certain grades.
Who uses SIST EN 10295:2003?
SIST EN 10295:2003 is used by foundries, purchasers, quality managers, welding engineers and test laboratories. Foundries use it to choose the alloy, melting route, heat treatment and welding conditions. Purchasers use it to specify the grade, delivery condition and required tests for high-temperature cast parts. Quality teams use it for inspection, acceptance, marking and test records.
What changed in SIST EN 10295:2003 from the previous edition?
SIST EN 10295:2003 is the Slovenian standard identical to EN 10295:2002.
Which standards are used with SIST EN 10295:2003?
SIST EN 10295:2003 uses EN 1559-1 and EN 1559-2. EN 1559-1 provides the general technical conditions of delivery for founding, while EN 1559-2 adds requirements for steel castings. The introduction says the standard should be used together with those documents, and where a clause has no added text, the corresponding clause of EN 1559-1 or EN 1559-2 applies.
What does the SIST EN 10295:2003 document contain?
SIST EN 10295:2003 contains a full grade list with chemical composition limits in Table 1 and room-temperature mechanical properties in Table 2. It also gives limits for unspecified elements in Table 3, plus informative data on welding in Annex A, creep properties in Annex B, maximum use temperatures in Annex C, and physical properties in Annex D.
Clause 6 covers melting, heat treatment, welding operations and further processing. Clause 8 covers sampling, test blocks, test methods, invalidation of tests, retests and sorting or reprocessing. Clause 9 to Clause 11 cover marking, packaging and surface protection, and complaints, so the standard supports specification, production, testing and delivery control.
