Stellite alloys are a family of completely non-magnetic and corrosion-resistant cobalt alloys of various compositions that have been optimised for different uses. Stellite alloys are suited for cutting tools, an example is Stellite 100, because this alloy is quite hard, maintains a good cutting edge at high temperature, and resists hardening and annealing.
Chromium (Cr) increases hardness, tensile strength, and toughness. increases resistance to corrosion, heat, and wear. more than 11% makes it "stainless", by causing an oxide coating to form. [61] carbide inclusions reduce wear, but bulk material is softer. Cobalt (Co) increases strength and hardness, and permits quenching in higher temperatures.
The main alloying elements are cobalt and nickel, but chromium, molybdenum and carbon are also added. Its exceptional properties are hardness, tensile strength, fracture toughness and ductility. [2] Aermet is weldable with no preheating needed. [3] AerMet alloy is not corrosion resistant, so it must be sealed if used in a moist environment.
Elastic properties describe the reversible deformation (elastic response) of a material to an applied stress.They are a subset of the material properties that provide a quantitative description of the characteristics of a material, like its strength.
The Rockwell hardness test is a hardness test based on indentation hardness of a material. The Rockwell test measures the depth of penetration of an indenter under a large load (major load) compared to the penetration made by a preload (minor load). [ 1 ]
Elements used in this alloy are one or more of the following other than titanium in varying amounts. These are molybdenum, vanadium, niobium, tantalum, zirconium, manganese, iron, chromium, cobalt, nickel, and copper. Beta titanium alloys have excellent formability and can be easily welded. [10]
