Exploring S45C Steel

S45C is a medium carbon steel material that belongs to Japanese Industrial Standard (JIS) steel. This kind of steel is widely used in machinery manufacturing, automobile industry and other fields due to its good mechanical properties and processing properties. S45C steel is widely used in machinery manufacturing, automobiles, ships and other industries, for example, it is used to manufacture complex mechanical parts, bearings, gears, etc., and is also used to manufacture key components such as automobile engines and transmissions.

1.Chemical composition
The chemical composition of S45C steel includes elements such as carbon (C), silicon (Si), manganese (Mn), phosphorus (P), chromium (Cr), nickel (Ni) and copper (Cu). The combination of these ingredients allows it to excel in strength and wear resistance while maintaining good processability. The specific chemical composition is:
Carbon (C): 0.42%-0.48%
Silicon (Si): 0.15%-0.35%
Manganese (Mn): 0.60%-0.90%
Phosphorus (P): ≤0.030%
Chromium (Cr): ≤0.20%
Nickel (Ni): ≤0.20%
Copper (Cu): ≤0.30%

2.Mechanical properties
The mechanical properties of S45C steel include tensile strength, yield strength and elongation. These performance indicators show that S45C steel has high strength and good toughness and can provide reliable support in a variety of engineering applications. The specific mechanical properties are as follows:
Tensile strength (σb): ≥686MPa
Yield strength (σs): ≥490MPa
Elongation (δ5): ≥17%
