Alloy compositions and devices including the compositions
Alloy compositions, including devices and instruments that include the compositions, are disclosed. The compositions have high hardness, strength, corrosion resistance, and biocompatibility. The compositions can be used to manufacture, for example, medical devices and products.
1. A medical device, comprising
an alloy comprising a stainless steel and greater than 50% by weight of one or more first elements selected from the group consisting of palladium, iridium, rhodium, gold, silver, and lead.
2. The device of claim 1 , wherein the stainless steel is a 300 series stainless steel.
3. The device of claim 2 , wherein the stainless steel is 316 stainless steel.
4. The device of claim 1 , wherein the alloy comprises greater than about 60% by weight of the first element.
5. The device of claim 1 , wherein the alloy comprises greater than about 70% by weight of the first element.
6. The device of claim 1 , wherein the alloy further comprises chromium and molybdenum.
7. The device of claim 1 , wherein the alloy is at least about 50% martensitic.
8. The device of claim 1 , wherein the alloy consists essentially of the stainless steel, one or more first elements, chromium, and molybdenum.
