Product Overview
StructuraRing-C22 is a premium cobalt alloy forged ring engineered for extreme-performance applications demanding exceptional strength, corrosion resistance, and thermal stability. Manufactured from ASTM F75-compliant cobalt-chromium-molybdenum alloy and processed via Hot Isostatic Pressing (HIP), this ring eliminates internal porosity and delivers uniform microstructure integrity—critical for mission-critical components in aerospace, medical implants, and energy systems. With precise dimensions of OD 1200mm × ID 800mm × H 200mm, it represents a high-precision forged ring solution tailored for large-diameter structural and rotational assemblies.
As a custom-engineered forged ring, StructuraRing-C22 leverages advanced open-die and ring-rolling forging techniques followed by full HIP consolidation—ensuring superior fatigue life and dimensional repeatability. Its composition meets stringent ASTM F75 specifications for biocompatibility and mechanical consistency, making it ideal for both implant-grade and industrial-scale applications where reliability cannot be compromised.
