Micro-Melt® Biodur® CCM Plus®

UNS #R31538

Micro-Melt® Biodur® CCM Plus® is a non-magnetic, cobalt-chromium-molybdenum alloy exhibiting high strength, corrosion resistance, and wear resistance. This alloy is a high carbon version of Biodur® CCM with improved forgeability and machinability that meets ASTM F799 requirements without thermochemical processing and that retains a high strength level after high temperature annealing. It is a wrought powder metallurgy product produced by vacuum induction melting (VIM) followed by gas atomization and hot isostatic pressing to produce 100% dense billets then processed by conventional steel-making practices to produce finished products and meets the requirements of ASTM F1537, ASTM F799, ISO 5832-12 and ISO 5832-4. This alloy is particularly well suited for applications where wear or fatigue properties are of major importance or where intricate high strength forgings are required.
