High Strength H11 Aerospace Fasteners
Chromium tool steels, also called H series steels, have relatively low carbon content and chromium content between 4.75% and 5.25%. Their unique toughness, abrasion resistance, and their ability to resist deformation even at extreme temperatures and under extreme stress make them ideal for use as tools — but also for aerospace fasteners.
The most commonly used varieties in aerospace are H11, H12 and H13. H11 is easy to work with. It can be welded, machined, forged, and cold worked with conventional methods. Its machinability rate is roughly 75% that of W group steels.
Characteristics of H11 Aerospace Fasteners
- – Extreme resistance to heavy loads, impact and stress
- – Superior thermal fatigue cracking resistance
- – Excellent resistance to thermal shock and gross cracking
- – Tensile strength of 289,000 psi
H11 Fasteners are used for:
H11 aerospace fasteners are ideal for use in highly stressed areas of an aircraft, such as its landing gear. Common aerospace bolts made of H11 are those in the MS21297 Series.
