C45 is a medium carbon steel grade widely used in engineering and industrial applications where higher strength and wear resistance are required. With a carbon content of approximately 0.45%, this steel offers a good balance between strength, toughness, and machinability.
It is commonly used in the manufacturing of shafts, gears, bolts, axles, and machine components that require high mechanical strength. C45 steel can be heat treated to improve its hardness and wear resistance, making it suitable for applications subjected to stress and friction. This material is widely used in automotive, machinery, and engineering industries due to its reliability and performance under demanding conditions. Its ability to undergo processes like forging, machining, and heat treatment makes it highly versatile.
Sanjay Sales supplies Medium Carbon Steel (C45) in various forms and sizes, ensuring compliance with industry standards and meeting diverse engineering requirements.
