Cobalt Alloy Steel Products
Cobalt is helpful in applications that take advantage of its wear resistance, corrosion resistance, magnetic characteristics, and strength at high temperatures.Cobalt Alloy Steel Products
Cobalt based metals are alloyed with chrome, nickel, and tungsten. Due to the high cost of these alloys, they are used where severe conditions prevail and require high temperature strength and hardness, excellent wear, galling, corrosion, and/or erosion resistance.
Due to the high chromium content (25% – 30% for the grades listed below) cobalt-based alloys provide superior corrosion resistance at high temperatures. The materials are more weldable than nickel-based alternatives. While not as strong as nickel alloys at lower temperatures, above about 1700°F / 930°C cobalt alloys show higher strength. Nickel melts at 2651°F / 1455°C while cobalt melts at 2723°F / 1495°C.
There is also data to demonstrate that casting processes which solidify directionally (centrifugal, for example) lead to improvements in rupture strength and thermal fatigue resistance.
MP35N® Nickel Cobalt Alloy
UNS R30035 | AMS 5844 | AMS 5845
MP35N® is a Multiphase® cobalt nickel-based superalloy, consisting of 35% Nickel and 35% Cobalt. MP35N® is produced using a 2-step melting process, the first step is a vacuum induction melted (VIM), this is then followed by vacuum arc remelted (VAR). This 2-step melt process ensures superior cleanliness and minimizes non-metallic inclusions and residual elements (such as carbon), that have deleterious effects on mechanicals and corrosion resistance. MP35N® can be aged to increase mechanical properties beyond those of stainless and nickel alloys, without sacrificing corrosion resistance. MP35N® can be supplied per AMS 5844 (Sol Treated and Cold Worked), and can then be age hardened to increase mechanical properties.

MP35N® NACE Nickel Cobalt Alloy
UNS R30035 | AMS 5845
MP35N® is a Multiphase® cobalt nickel-based superalloy, consisting of 35% Nickel and 35% Cobalt. MP35N® is produced using a 2-step mel ng process, the first step is a vacuum induction melted (VIM), this is then followed by vacuum arc remelted (VAR). This 2-step melt process ensures superior cleanliness and minimizes non-metallic inclusions and residual elements (such as carbon), that have deleterious effects on mechanicals and corrosion resistance. MP35N® NACE is produced specifically for use in sour gas (H₂S) service. It is produced by aging, to restrict hardness and limit the susceptibility to cracking in these environments.
