Description
ST37.4 cold rolled steel tubes are specifically engineered for use in hydraulic cylinders, known for their precision and mechanical strength. This description covers the key aspects and advantages of these tubes.
Standard: Compliant with DIN 2391, which specifies the technical delivery conditions for seamless precision steel tubes.
Steel Grade: ST37.4
Condition: Cold rolled to achieve desired mechanical properties and surface finish.
Typical chemical composition of ST37.4 steel includes:
Carbon (C): ≤ 0.17%
Silicon (Si): ≤ 0.35%
Manganese (Mn): 0.40 - 0.80%
Phosphorus (P): ≤ 0.025%
Sulfur (S): ≤ 0.025%
Tensile Strength: 340-480 MPa
Yield Strength: ≥ 235 MPa
Elongation: Minimum 25%
Hardness: Typically around 120-160 HB (Brinell hardness)
Cold Rolling: Enhances the surface finish and mechanical properties by reducing the tube diameter and wall thickness through rolling processes.
Heat Treatment: Often normalized to refine the grain structure, improve ductility, and relieve internal stresses.
Surface Treatment: Options include phosphating and oiling to enhance corrosion resistance.
Hydraulic Cylinders: Ideal for hydraulic cylinder applications due to their precision, strength, and surface quality.
Pneumatic Systems: Used in systems requiring high strength and tight dimensional tolerances.
Automotive Industry: Suitable for components such as shock absorbers and steering systems.
Industrial Machinery: Applied in equipment that demands precise and reliable components.
Construction Equipment: Utilized in heavy machinery for robust performance under high stress.
Precision: Cold rolling ensures tight dimensional tolerances, which are crucial for hydraulic cylinder performance.
Surface Quality: Smooth surface finish reduces friction and wear, enhancing the lifespan of hydraulic components.
Mechanical Strength: High tensile and yield strength make these tubes suitable for high-pressure applications.
Corrosion Resistance: Phosphating and oiling improve resistance to environmental factors.
Durability: High resistance to mechanical stress ensures long service life even under demanding conditions.
Size Range: Available in various diameters and wall thicknesses to meet specific hydraulic cylinder requirements.
Tolerances: Maintained to precise standards to ensure consistency and reliability.
Quality Control: Rigorous testing including dimensional inspection, mechanical testing, and non-destructive testing.
Certification: Provided with certifications as per DIN 2391 standards, including mill test certificates (MTC) to verify compliance with specifications.
ST37.4 cold rolled steel tubes are the preferred choice for hydraulic cylinders due to their superior precision, mechanical strength, and excellent surface quality.
