Precision Cold Drawn Steel Tubes

Precision Cold Drawn Steel Tubes from Newton are seamless tubes manufactured through a cold-drawing process to achieve tight dimensional tolerances, a smooth internal and external surface finish, and controlled mechanical properties required for high-precision mechanical and hydraulic applications. Unlike standard hot-finished pipe, these tubes are drawn through dies in successive passes, refining wall thickness uniformity and surface quality with each pass.

Precision Cold Drawn Steel Tubes

Newton manufactures Precision Cold Drawn Tubes to DIN 2391, ASTM A519 and equivalent international standards, in outer diameters from 6mm to 200mm, with wall thicknesses and tolerances specified to suit the end application. The cold-drawing process is followed by stress-relief or normalizing heat treatment as required, producing tubes with consistent mechanical properties, minimal ovality, and a surface finish suitable for direct use as a machined or hydraulic component without extensive secondary processing.

These tubes are widely used in hydraulic and pneumatic cylinder manufacturing, automotive components such as axles, propeller shafts and steering columns, bearing races, agricultural machinery, and general precision engineering applications where dimensional accuracy directly affects component performance. Their controlled wall thickness and roundness make them especially suited to applications involving honing, machining or press-fit assembly.

Each production batch is checked for outer diameter, wall thickness, ovality, straightness and surface finish using precision measuring equipment, alongside mechanical property testing to confirm compliance with the specified grade and heat-treatment condition. Mill test certificates accompanying each dispatch record chemical composition, mechanical properties and dimensional inspection results.
