Endurotube ground 40x2,0
These tubes were first grounded with grain 180 and then with grain 320
Ground tubes have the following advantages:
- Less sensitive to cracks
- Better weld ability
- Nice appearance
- Better bendability
- Better finish
- No more sanding before spraying
These tubes have the same mechanical values as our other 25CRMO4 tubes.
ENDUROTUBE GROUND 25CrMo4 +SR are seamless cold-drawn precision tube of alloy steel with high mechanical properties. Specially produced to our wishes and to the wishes of the high-quality car- and motorsport segment. 25CrMo4 is derived from its two most important alloying elements; Chromium (Cr) and Molybdenum (Mo) which act as reinforcing elements in comparison with mild carbon steel. Due to the excellent strength to weight ratio it is widely used in the racing and aviation industrie. Very easy to weld. The surface of ENDUROTUBE is ground, inside and outside free from scale and oiled. Each tube features a marking with: Dimension in mm, Certificate number, Heat Number and Article Number.
It is important to know that not all chrome molybdenum tubes are equally produced in the market. Over the years, we know from a number of factories that produce this material, that they do not meet the high quality requirements that we and our customers demand.
On request we can provide all our 25CrMo4 tubes with an inspection certificate EN 10204-3.1.
