GH4169 Bolts

Описание: GH4169 bolts are high-performance superalloy fasteners used primarily in extreme environments.
Key Characteristics
Material: Nickel-based superalloy with a face-centered cubic (FCC) structure.
Performance: Maintains exceptional high-temperature mechanical strength, chemical stability, and load-bearing capacity.
Manufacturing: Threads are typically formed via cold thread rolling to enhance strength, though this can sometimes cause metallographic folding at the crest and root.
Strengthening: Advanced techniques like Laser Shock Peening (LSP) are used to improve surface integrity, microhardness, and fatigue life (potentially doubling the fatigue cycles).
