Cobalt Superalloys
Phynox, UNS R30003, (Elgiloy) is an austenitic hardenable superalloy on cobalt basis (40 % Co, 20 % Cr, 16 % Ni and 7 % Mo). Its mechanical strength may exceed 2,600 N/mm2, after the hardening. The maximum reachable tensile strength depends however significantly on the preceding cold deformation. It is non-magnetic, very resistant to corrosion (better results than any other stainless steel) and temperature resistant. Its high elasticity modulus (220 kN/mm2) combined with an elongation limit that can be over 1,800 N/mm2 makes Phynox an exceptional alloy for spring application. Lamineries MATTHEY SA delivers Phynox strips according the following standards: ASTM F1058 (surgical implants), ISO 5832-7 (surgical implants), AFNOR NF S 90-403 (surgical implants), AMS 5875, AMS 5876 and NACE MR0175.
