YANGSEN TUBE
We develop and produce rolled and drawn precision and profile steel tubes for various industrial sectors using tailored materials and processes.
Camshaft assembled
Jansen Steel Tubes produces welded-drawn precision steel tubes made of standard materials and high-tensile steel grades for assembled camshafts. For the manufacturers of camshafts, accurate concentricity, high degrees of roundness and straightness as well as stringent dimensional tolerances are important aspects in the selection of tubes. Low levels of surface decarburisation allow a partial hardening. As a result of the trend towards light-weight design, high-tensile materials are increasingly in demand. The use of modern high-tensile materials allows further weight savings by reducing the wall thickness while maintaining the comparable physical properties.
Tube requirements
■ High strength values (elongation at break, tensile strength)
■ High torsional strength and reverse bending strength
■ High geometrical accuracy
■ Excellent surface condition
■ High levels of strength and hardness after Q+T
