Overview

SIST EN 4566:2022 is a European standard established by CEN that specifies the requirements for the heat-resisting alloy CO-PH4101 (CoCr20W15Ni). This high-performance alloy is vacuum melted, solution treated, and supplied in forging form with a diameter (De) of up to 100 mm. The standard is part of the aerospace series, tailored specifically for aerospace applications demanding materials with exceptional heat resistance and mechanical strength.

The alloy’s controlled composition and treatment processes ensure reliability and optimal performance in demanding aerospace environments. SIST EN 4566:2022 aligns with other aerospace metallic material standards and prescribes chemical, physical, and mechanical properties to guarantee consistent quality.

  • Minimum proof stress (Rp0.2) of 340 MPa
  • Tensile strength ≥ 860 MPa
  • Elongation ≥ 35% for ductility
  • Hardness not exceeding 282 HB
  • Temperature resistance verified at 815 °C with rupture stress of 165 MPa and elongation at rupture ≥ 10%
• Testing and Inspection:
  • Compliance with EN 4700-006 for testing, marking, and dimensional inspection
  • Product qualification program agreed upon between manufacturer and purchaser to ensure standards adherence
• Scope and Application:
  • Specifically developed for aerospace components that require high heat resistance in forged parts up to 100 mm diameter in size
• Standardization and Compliance:
  • Harmonized across multiple European countries enforced by national standards bodies
  • Developed under Aerospace and Defence Industries Association of Europe - Standardization (ASD STAN) guidance

Applications

The SIST EN 4566:2022 standard alloy CO-PH4101 is utilized extensively in aerospace sectors where materials are subject to high temperatures and demanding mechanical loads, including:

• Jet engine components: turbine blades, hot section parts requiring resistance to oxidation and mechanical stress during operation
• Aerospace structural parts: heat-resistant forgings in airframes where high strength and temperature endurance are critical
• Gas turbine assemblies: environments where stable mechanical performance at elevated temperatures is mandatory
• High-temperature fasteners and fittings: requiring excellent corrosion and oxidation resistance combined with durability under thermal stress

This alloy’s unique composition and processing standards assure superior performance, enhancing the safety, reliability, and lifespan of aerospace hardware.
