Product Description
Cobalt Base Alloy Bars L605 are a class of high-temperature alloys primarily based on metallic cobalt, strengthened by adding elements such as chromium, tungsten, molybdenum, nickel, and carbon. Renowned for their exceptional high-temperature strength, superior wear resistance, outstanding corrosion resistance (especially to hot corrosion), and excellent thermal fatigue resistance, these alloys maintain structural integrity and functionality in extreme environments (e.g., high temperature, high pressure, severe wear, oxidation, and molten metal corrosion). They are the material of choice for critical applications in aerospace engines, gas turbines, chemical equipment, and wear-resistant components.
Maintains superior tensile strength and creep resistance at temperatures up to 1000°C or higher, significantly outperforming many stainless steels and nickel-base alloys.
Exhibits extremely high resistance to sliding wear, abrasive wear, and erosive wear (especially alloys containing carbide-strengthening phases), resulting in long service life.
Forms a dense, stable chromia (Cr₂O₃) protective layer at high temperatures, resisting oxidation in air or oxygen-containing environments.
Offers excellent resistance to "hot corrosion" (high-temperature sulfidation/oxidation) caused by combustion of fuels containing sulfur, vanadium, and other impurities – a key advantage over some nickel-base alloys.
Demonstrates good corrosion resistance in numerous acids, alkalis, and molten metal environments.
Withstands repeated heating and cooling cycles without significant crack formation, ideal for components experiencing severe thermal cycling.
Achieves dual strengthening via solid solution elements (Cr, W, Mo) and hard carbide phases (e.g., Cr₂₃C₆, WC, W₂C), delivering comprehensive performance.
Some cobalt-base alloys offer good weldability (requiring specific procedures) and can be processed into complex parts via casting, forging, powder metallurgy, and machining (though generally more challenging to machine than austenitic stainless steels).
