GCr18Mo is a type of bearing steel which owes its excellent mechanical properties primarily to carbon and chrome being its main ingredients. This steel has a composition that is similar to that of the bearing steel AISI 52100, yet still has a higher wear resistance in comparison.
GCr18Mo is widely used for a variety of applications in industries such as automotives, aerospace, and other machinery. The steel is usually hardened and tempered, using nitriding, vacuum hardening, and subzero treatment. These heat treatments are used to ensure that the steel is able to retain its luster and shape even under extreme pressures and temperatures.
GCr18Mo has great oxidation resistance due to its high chromium content, meaning that it is widely used in parts exposed to high temperatures. The steel forms a thin protective oxide layer when heated and exposed to the atmosphere. This oxide layer helps to prevent the part from corrosion and the steel from rusting. The steels excellent wear resistance also makes it an ideal material for components that come into contact with one another, such as gears and bearing surfaces.
The excellent hardness and strength of this steel also makes it an ideal material for a variety of machining operations. GCr18Mo is able to maintain a high level of strength even when subjected to extreme pressures and temperatures, which is why it is often used in aerospace and automotive parts. Other components that are made out of this steel include shafts, connecting rods, springs, and bolts.
Finally, GCr18Mo is extremely heat resistant and has excellent wear resistance, making it an ideal material for various applications. From automotive and aerospace components to metalworking operations, the steel has found popularity in all industries. The metal is also used by artists for its machinability and brightly polished finish. This versatile steel can be used for a variety of applications and is well-suited for use in both industrial and artistic contexts.
