Benefits BioDur 108 Alloy

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]
