C 45
Carbon Steel C 45, also known as C45 steel, is a widely used medium carbon steel with good tensile strength, hardness, and wear resistance. It is a common material in engineering and manufacturing due to its versatile properties and affordability. Let's delve into the specifics of C 45 steel:
Steel Properties
Tensile Strength: Typically ranges from 570 to 700 MPa (82 to 101 ksi) depending on the heat treatment condition.
Yield Strength: Varies widely based on the heat treatment and can range from 330 to 580 MPa (48 to 84 ksi).
Elongation: Around 14-22% in the normalized or annealed condition.
Hardness: Typically, the hardness after heat treatment is around 160-220 HB (Brinell Hardness).
Application
Shafts and Axles: Due to its good combination of hardness and toughness.
Gears: Especially where high strength and wear resistance are required.
Forging and Heat Treatment: Commonly used for making parts requiring high surface hardness.
General Engineering: Machine parts, spindles, bolts, and nuts.
