S45C Chemical Composition Standards And Properties
S45C is a medium carbon steel with a chemical composition of:
- Carbon (C): 0.42%-0.50%
- Silicon (Si): 0.15%-0.35%
- Manganese (Mn): 0.60%-0.90%
- Phosphorus (P): 0.030% max
- Sulfur (S): 0.035% max
The properties of S45C include:
- Density: 7.85 g/cm3 (0.284 lb/in3)
- Hardness: Rockwell hardness of 60-66 HRC
- Tensile strength: 570-700 MPa (82-101 ksi)
- Yield strength: 335-405 MPa (48-59 ksi)
- Elongation: 13-25%
- Properties: good mechanical properties, such as high tensile strength, good toughness, and excellent hardenability. It also has good machinability and can be easily welded.
- Applications: used in various industries, such as automotive, machinery, and construction. It is commonly used to manufacture gears, shafts, axles, and other structural parts.
- Quality control: strict quality control measures should be implemented. This can include proper heat treatment, careful selection of raw materials, and thorough testing of the finished product.
- Environmental impact: it is important to consider its environmental impact. Recycling and proper disposal of waste materials should be taken into account to minimize its impact on the environment.
