DESCRIPTION
SCM440 HOT Non-Alloy Steel is a low-carbon steel alloy containing small amounts of Chromium and Molybdenum. It is known for its high strength, good wear resistance, and machinability, commonly used in applications requiring high durability and hardness.
Key Characteristics of SCM440 HOT Non-Alloy Steel:
- Chemical Composition:
- Carbon (C): Approximately 0.38-0.43%, which enhances the hardness and strength of the steel.
- Manganese (Mn): Approximately 0.60-0.90%, which improves toughness and impact resistance.
- Chromium (Cr): Approximately 0.90-1.20%, which increases strength and wear resistance.
- Molybdenum (Mo): Approximately 0.15-0.30%, which enhances strength at high temperatures and improves mechanical properties.
- Silicon (Si) and Phosphorus (P): Maintained at low levels to ensure good weldability and machinability.
- Sulfur (S): Low content to improve machinability without compromising strength.
- Physical Properties:
- Tensile Strength: High, suitable for applications requiring significant strength and load-bearing capacity.
- Hardness: Can be hardened and tempered to achieve desired hardness.
- Wear Resistance: Good, due to the presence of Chromium.
- Machinability: Excellent, easily machinable using traditional methods.
- Applications:
- Machinery Manufacturing: Used for components like shafts, gears, and load-bearing parts.
- Automotive Industry: Used in manufacturing parts such as camshafts and drive components.
- Heavy Industry: Suitable for high-load and wear-resistant structural components.
- Industrial Equipment: Used in machinery and equipment with stringent requirements for durability and wear resistance.
- Shape and Size:
- SCM440 HOT steel is commonly supplied in bars, plates, tubes, and customized products according to customer requirements.
Manufacturing and Processing:
- SCM440 HOT steel is typically produced through hot rolling and can be heat-treated (such as quenching and tempering) to enhance mechanical properties. It is machinable using traditional methods like turning, milling, and grinding.
