Definition of Machinery Steel
Machinery steel is a type of steel specifically designed and used in the manufacturing of machines and industrial equipment. This steel possesses particular characteristics and properties that make it suitable for environments requiring high strength, wear resistance, heat resistance, and excellent mechanical performance.
Machinery steel plays a crucial role in the production of machinery, industrial equipment, heavy vehicles, and various heavy-duty tools. Selecting the right type of machinery steel is a key factor in ensuring these machines and equipment operate effectively and safely.
Types of Machinery Steel
1. HQ Series 7
HQ Series 7 is a category of machinery steel with medium to high strength levels, suitable for general machine components up to medium-heavy load applications.
Characteristics:
- Good tensile strength and fatigue resistance
- Can undergo heat treatment (quenching & tempering)
- Good machinability
- Stable during machining and resistant to deformation
- Grades: HQ 705, HQ 709, HQ 760
2. HQ Series 8
HQ Series 8 is a higher-spec machinery steel compared to Series 7. This series undergoes ultrasonic testing, vacuum degassing, and peeling processes, resulting in cleaner, more homogeneous materials free from internal defects with better surface precision. It is suitable for heavy-duty and high-precision applications.
Characteristics:
- High strength and excellent toughness
- Superior wear resistance
- More homogeneous material structure
- Suitable for components requiring high fatigue resistance
- Can be hardened to a high level (high hardness capability)
- Grades: HQ 805, HQ 809
Functions of Machinery Steel
- Serves as the primary material for machine components requiring mechanical strength
- Supports motion, rotation, friction, and heavy loads
- Used for parts that require wear resistance, hardness, and dimensional stability
