EN 10305-1 EN 10305-2 Precision Steel Pipe 4-120mm Diameter with ±0.10mm Tolerance for Aerospace and Automotive Applications
Precision steel pipe is a high-precision, high-brightness seamless steel tube manufactured through cold drawing or cold rolling processes. With inner and outer diameter accuracy within 0.2mm, these pipes offer excellent bending and torsional strength while maintaining lightweight properties, making them ideal for precision mechanical components and engineering structures.
Exceptional dimensional accuracy with diameter and wall thickness tolerances meeting rigorous mechanical equipment requirements.
Excellent strength-to-weight ratio with superior bending and torsional capabilities.
Available in carbon steel, alloy steel, and stainless steel materials for enhanced durability.
Smooth inner and outer surfaces free from impact burrs, facilitating easy machining and fabrication.
- Cold Drawing: Most common method involving cold processing of hot-rolled steel pipes to achieve precise diameter and wall thickness specifications.
- Cold Rolling: Multi-pass rolling and drawing process that gradually adjusts and controls steel pipe dimensions.
- Cold Extrusion: Heating steel billets to appropriate temperatures then extruding through specialized dies to create hollow pipes with uniform wall thickness and high surface finish.
Available thicknesses: 0.5mm, 0.8mm, 1mm, 1.2mm, 1.5mm, 1.8mm, 2mm
