S50C HOT Non-Alloy Steel is a medium carbon steel known for its high hardness and tensile strength, widely used in mechanical engineering. With approximately 0.50% carbon content, S50C offers a good balance between hardness and machinability, making it a popular choice for applications requiring high strength and load-bearing capabilities.

Key Characteristics of S50C HOT Non-Alloy Steel:

- Chemical Composition:
- Carbon (C): Approximately 0.47% - 0.53%
- Manganese (Mn): Approximately 0.60% - 0.90%
- Silicon (Si): Approximately 0.15% - 0.35%
- Phosphorus (P): Max 0.030%
- Sulfur (S): Max 0.030%
- Iron (Fe): The remainder

- Physical Properties:
- High Tensile Strength: S50C has high tensile strength, enhancing the product's load-bearing capacity and durability.
- Moderate Hardness: With moderate hardness, S50C can be easily machined and heat-treated.
- Machinability: S50C is well-suited for forging, hot rolling, and other mechanical processing.
- Wear Resistance: While not as wear-resistant as alloy steels, S50C provides good durability in non-abrasive applications.

- Applications:
- Mold Manufacturing: S50C is commonly used for making molds, plastic mold bases, and stamping dies.
- Mechanical Engineering: Used in machine parts, shafts, gears, and other components requiring high strength and precision.
- Cutting Tools: Suitable for making cutting tools, knives, and load-bearing parts in the engineering industry.

- Shape and Size:
- S50C HOT steel is typically supplied in plate, round bar, or other shapes according to specific application requirements.

Manufacturing and Processing:
- S50C is produced through steelmaking and heat treatment processes to achieve desired mechanical properties. Hot rolling is used to create S50C steel products with high strength and precision.
