Engineering steel tubes

Seamless hot-finished steel tubes accor­ding to EN10297

Do you have high machining costs due to unfavorable blank dimensions?
Are you dissatisfied with the machining properties of your tubes?
Does the eccentricity of hot-rolled tubes bother you?
Do you have problems with the straightness of hot-rolled tubes?

Then we recommend tubes in the grades E470+AR, 20MnV6 and E590K2+QT, which are characterized by the tightest tolerances and a special straightness (deviation from straightness up to 1.5:1000 mm in relation to the delivery length). Compare our materials.

  • Less material used due to pipes as close to the final contour as possible
  • Improved strength and machining properties due to controlled sulphur content
  • higher cutting speeds with almost the same tool wear
  • Application-oriented material selection with which manufacturing costs can be saved
