ASTM F1537 Alloy 1 : Wrought 28Cr-6Mo Alloys for Surgical Implants (UNS R31537 )

ASTM F1537 is a cobalt chrome molybdenum alloy used in medical and surgical devices requiring high fatigue strength such as orthopedic total joint replacement.

 

This alloy of Cobalt-Chromium-Molybdenum it meets the strictest requirements regarding biocompatibility and corrosion resistance. It is non-magnetic.

 

ASTM F1537 is especially applicable for medical implants (endoprothesis and osteosynthesis) wherever high mechanical stress is expected. It is also widely used in the watch making industry as well as other industries where hardness, toughness, ductility and corrosion resistance are required.

 

We are suppliers of Cobalt Chrome Molybdenum (ASTM F1537 Alloy 1) in round bar stock, sometimes known as chrome moly steel. This is a cobalt-chromium-molybdenum (Co-Cr-Mo) alloy used for machining and forging stock, especially in the medical implant industry. The molybdenum improves strength and heat resistance, while the chromium provides oxidation and corrosion resistance. This material is highly biocompatible, making it ideal for surgical implants such as knee, hip, and shoulder replacements.

 

Our CoCrMo bar stock (F1537 Alloy 1) is primarily used in the medical manufacturing industry, where its high fatigue life is appropriate for repeated movements found in joints like knees and hips. Biocompatibility is similar to titanium, with greater mechanical strength for load bearing applications.

This low alloy steel features high strength, hardness, toughness, and creep-resistance that also makes it difficult to machine when compared to mild carbon steels. Tools can wear rapidly with this product, and work hardening should be minimized with sharp tools and low vibration machines and mounts. Difficulty in machining is comparable to titanium alloyed steel. We can supply custom precision ground sizes and tolerances upon demand.
