Specializing in the supply of Grade ASTM F1537 Alloy 1 raw materials and processing, alloys, stainless steel, and metal quality development.
This material is a Cobalt Chrome 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.
This low alloy steel features high strength, hardness, toughness, and creep-resistance. Difficulty in machining is comparable to titanium alloyed steel. Custom precision ground sizes and tolerances can be supplied upon demand.
Our CoCrMo bar stock is primarily used in the medical manufacturing industry for load-bearing applications:
| Element | Content (%) |
|---|---|
| Cobalt | 66.00 max |
| Chromium | 27 max |
| Nickel | 0.2 max |
| Molybdenum | 5.5 max |
| Carbon | 0.04 max |
| Condition | 0.2% Yield Strength | Tensile Strength | Elongation (4D) | Hardness (HRC) |
|---|---|---|---|---|
| Annealed | 585 MPa | 1035 MPa | 25% | 30 |
| Warm Worked | 930 MPa | 1310 MPa | 26% | 40 |
| Hot Worked | 760 MPa | 1100 MPa | 25% | 33 |
