Vehicle Steel Tubes And Pipes , Hollow Thin Wall Seamless Steel Tube For Cam

Steel Tubes and Pipes for Vehicle EN10305-2 Delivery Condition +N Wholesale hollow Thin wall Seamless Steel Tube for camshaft

Welded precision steel tubes for stabilisers (passenger cars), monobloc drive shafts and gear shafts.

The excellent surface quality of the welded precision steel tubes has a positive effect on the lifetime of the finished products. Due to our innovative furnace technology, we are able to adapt the carbon content of the edge layer to our customers' particular needs.

Seamless precision steel tubes for stabilisers (commercial vehicles), monobloc drive shafts and gear shafts.

Weld-drawn tubes to produce propeller shafts for the automotive industry. As part of processing tubes are partly drawn in at the ends to meet high demands to reshaping properties and the quality of the weld seam. Stringent tolerances in terms of roundness, straightness and wall thickness are necessary to prevent running noise and vibrations. This guarantees smooth propeller shaft operation within the vehicle. The use of cutting-edge air hardening steel materials enable additional options to cut weight.

Requirements

• Excellent reshaping properties (drawing in, hammering)
• High torsional strength and durability
• Excellent welding properties
• High levels of geometrical accuracy (eccentricity, roundness)
• Excellent surface-finish condition

Material properties

• High torsional strength and fatigue strength
• Excellent reshaping properties (drawing in, hammering)
• Homogeneous strength properties and ductility
• Excellently suitable for welding
• Potential to reduce wall thickness
