What is Carbon Steel shaft?
Carbon Steel Shaft refers to a shaft made from carbon steel, a popular choice in various industries for its strength, durability, and affordability. Carbon steel, known for its high carbon content, offers excellent hardness and wear resistance, making it suitable for applications requiring robust components that can withstand heavy loads and harsh environments. Carbon Steel Shafts are widely used in manufacturing machinery, automotive components, agricultural equipment, and construction tools where reliability and cost-effectiveness are crucial factors.
The CARBON STEEL SHAFT M2*L8 is a high-performance mechanical component designed for durability and precision in demanding industrial applications. Below are its key characteristics with technical specifications:
1. Material Composition: The shaft is manufactured from medium-carbon steel (ASTM A108), typically containing 0.30–0.60% carbon, which provides an optimal balance of strength (tensile strength: 570–700 MPa) and machinability.
2. Dimensional Precision: The M2*L8 designation indicates a metric shaft with a 2 mm nominal diameter and 8 mm length, adhering to ISO 286-2 tolerance standards (h6 grade) for tight fits in precision assemblies.
3. Surface Hardness: Through heat treatment processes like quenching and tempering, the shaft achieves a surface hardness of 40–45 HRC (Rockwell C scale), significantly improving wear resistance while maintaining core toughness.
4. Fatigue Resistance: The material's endurance limit is approximately 50–60% of its tensile strength (285–420 MPa), making it suitable for cyclic loading applications with a safety factor of 2.0–2.5 under dynamic conditions.
5. Corrosion Protection: Standard shafts feature a 5–10 µm zinc plating (per ASTM B633) or black oxide coating, providing 500+ hours of salt spray resistance in accordance with ASTM B117 testing standards.
6. Thermal Stability: The shaft maintains dimensional stability within ±0.01 mm across a temperature range of -20°C to +120°C, with a thermal expansion coefficient of 11.5 µm/m·°C, matching most industrial bearing materials.
