The BioDur®† 108 alloy offers all the advantages of commonly used medical grade stainless steels—like 316L, 734, and 22-13-5—along with some additional benefits.
High Tensile and Fatigue Strength
BioDur 108 has higher tensile and fatigue strength than 316L, 734, and 22-13-5 alloys.[1,2]
Low Nickel Content
BioDur 108 contains less than 0.05% nickel, which is intended to help minimize nickel exposure.[2] Nickel sensitivity among humans is reportedly approximately 14% , although extreme metal sensitivity has been reported in only about 1% of joint replacement patients.[3]
| Nickel content by percent-weight. | |||
| BioDur 108 | 316LS (ASTM F138) |
BioDur 22-13-5 (ASTM F1314) |
BioDur 734 (ASTM F1586) |
|---|---|---|---|
| 0.05% | 13 – 15.5% | 11.5 – 13.5% | 9 – 11% |
Corrosion Resistance
Pitting and crevice corrosion resistance is superior to 316L alloy and equivalent to 734 and 22-13-5 alloys.[2]
