Aerospace turbine and engine parts require high‑strength steels and nickel alloys with excellent fatigue, creep, and temperature resistance. Key quality features include certified materials, controlled heat treatment, non‑destructive testing, and full traceability to aerospace standards.
Turbine and engine parts in aerospace applications operate under extreme conditions, including high temperatures, high rotational speeds, severe mechanical loads, and aggressive environments. Material requirements are therefore exceptionally demanding, with a strong focus on high‑temperature strength, creep resistance, fatigue performance, oxidation resistance, and long‑term dimensional stability. Materials must maintain mechanical integrity over extended service life while meeting strict safety and certification standards.
Key materials include high‑alloy steels for shafts, disks, and structural engine components, as well as nickel‑based superalloys for hot‑section parts exposed to elevated temperatures. Martensitic and precipitation‑hardened steels are used where high strength and wear resistance are required. Material purity, controlled grain structure, and precise chemical composition are essential to prevent fatigue and creep failures. Quality features include vacuum‑melted materials, fully certified supply chains, validated heat‑treatment processes, and tight process control. Comprehensive non‑destructive testing, dimensional inspection, and full traceability ensure compliance with aerospace standards and guarantee safe, reliable engine operation.
Krómötvözetű rozsdamentes acél nagy keménységgel, kopásállósággal és jó korrózióállósággal edzett és hőkezelt állapotban. A BÖHLER N695 típust általában olyan alkatrészekhez használják, amelyeknél akár 58 HRC keménységre és kopás-, korrózió- és oxidációállóságra van szükség, például golyók, görgők, tűk és gyűrűk korrózióálló csapágyakhoz – de a felhasználás nem korlátozódik kizárólag ezekre az alkalmazásokra.
