Description:
The DIN2391/C St37.4 steel tubing is meticulously engineered to meet the stringent requirements of high-pressure hydraulic systems, offering exceptional performance and reliability. Crafted from low carbon steel (St37.4), this tubing undergoes a seamless cold-drawn manufacturing process, ensuring uniformity and precision in dimensions and surface finish. It is available in two wall thickness options, 10X1mm and 10X1.5mm, to accommodate varying pressure requirements. The tubing is delivered in two key conditions: +N (Normalized) and NBK (Normalized, cold finished, stress relieved), each enhancing mechanical properties and dimensional stability.
Key Features:
Material & Specifications
Base Material: Low carbon steel St37.4
Manufacturing Method: Seamless cold-drawn
Wall Thickness Options: 10×1mm / 10×1.5mm
Delivery Conditions: +N (Normalized) / NBK (Normalized + Cold Finished + Stress Relieved)
Key Process & Performance Advantages
Annealing Treatment: Effectively softens the material structure, significantly improving ductility and eliminating internal stresses. This ensures easier on-site processing and installation while maintaining structural stability.
High-Pressure Suitability: Specifically engineered for reliable performance in high-pressure hydraulic systems, offering robust pressure resistance and long-term operational safety.
Seamless Integrity: Cold-drawn seamless construction provides uniform material density and enhanced mechanical strength, eliminating potential weak points under cyclic loading conditions.
