Material search
Material description
The material 2.4952 is a nickel-chromium alloy with good mechanical properties. Due to the additional aluminium and copper alloys, an ageing heat treatment can be carried out. This allows correspondingly high fatigue and creep strengths to be realised for applications of up to 815°C.
This alloy is characterised by very good corrosion resistance and oxidation resistance. In addition, 2.4952 (Alloy 80 A) has good scale resistance even at high temperatures.
AN OVERVIEW OF THE PROPERTIES OF 2.4952:
- Good corrosion and oxidation resistance
- High fatigue strength
- High tensile and creep strength
Applications
- Chemical industry
- Gas turbines
- Shipbuilding
- Environmental technology
- Screws
- Motor technology
