Micro-Melt® Biodur® CCM Low Nickel

UNS #R31537

Micro-Melt® Biodur CCM Low Nickel is a non-magnetic, cobalt-chromium-molybdenum wrought alloy exhibiting high strength, corrosion resistance, and wear resistance. This alloy is a powder metallurgy version of BioDur CCM (ASTM F 1537 Alloy 1), which is a high nitrogen, low carbon wrought version of ASTM F 75 cast alloy. It features a homogeneous chemistry and microstructure with small, uniformly distributed carbides. This alloy is particularly suited for small diameter bar and wire applications, where high strength or high fatigue resistance is required. Micro-Melt® Biodur CCM is produced by vacuum induction melting (VIM) followed by gas atomization and hot isostatic pressing to produce 100% dense billets then processed by conventional steelmaking practices to produce millform products. Hot isostatically pressed (HIP'd) near net shapes and loose powder are also available. Micro-Melt BioDur CCM is generally supplied in the warm-worked condition since this provides the highest mechanical properties, highest hardness, finest grain size, and highest fatigue strength.
