GADS Vitallium
UNS #R31539
Micro-Melt® GADS Vitallium alloy is a non-magnetic, cobalt-chromium-molybdenum wrought alloy exhibiting high strength, corrosion resistance, and wear resistance. Its attributes inlcude a homogeneous chemistry and microstructure, small, uniformly distributed carbides, fine austenitic grain size, improved forgeability, and machinability, and it retains a high strength level after high temperature annealing. This alloy is a powder metallurgy version of BioDur CCM with purposeful additions of rare-earth lanthanides for dispersion strengthening. This provides increases strength and fatigue performance. This alloy is equivalent to ASTM F 1537 Alloy #3 and meets the requirements of ASTM F1537, as well as ASTM F799 without thermal-mechanical processing. Produced by vacuum induction melting (VIM) followed by gas atomization and hot isostatic pressing to produce 100% dense billets, these billets are then processed by conventional steel-making practices to produce finished products.
