Steels for the aerospace industry: top quality for the highest demands

The aerospace industry places extreme demands on the materials used in aircraft, spacecraft and engines. Choosing the right steels is crucial to meet the highest safety and performance standards. Our aerospace steels, heat-resistant stainless steels and nickel-based alloys are optimized to withstand the most demanding conditions - from enormous temperature loads to high mechanical requirements and extreme environments.

What makes our aerospace steels special

The steels used in the aerospace industry must have an outstanding combination of properties. Our materials offer:

  • High strength: A key requirement in aerospace to maximize both efficiency and safety.
  • Corrosion resistance: Particularly in aerospace, where extreme weather and environmental influences occur, high resistance to corrosion is essential.
  • Heat and cold resistance: Whether during launches into the stratosphere or during re-entry into the earth's atmosphere - our steels can withstand extreme temperatures.
  • Outstanding fatigue strength: Particularly in engines and other highly stressed components, the materials used must be able to withstand extreme loads while remaining durable and reliable.

The diversity of our stainless steels and other aerospace materials therefore offers options for every challenge. Our range includes the following materials, which we also stock in accordance with special OEM regulations:

  • 1.4548
  • 1.7734
  • 1.4108, or X90CrMoV18
  • 1.4044, or X22CrNi17
  • 1.4944
  • 1.6604, or 30CrNiMo8
  • 1.5924, or 15CrNi6
