Comparison of the mechanical values of the materials that we keep in stock (with an assumed wall thickness of 25 mm)
The high mechanical values (yield strength/tensile strength) of the material we supply make possible a considerable reduction in dimensions and wall thickness, and nevertheless meet the guaranteed elongation and toughness values while still providing good weldability.
This is based on DIN EN 13480-3. It also applies to the following graphic representation.
- Are your cylinders too heavy?
- Do your cylinders require too much space?
- Could your cylinders use higher pressure stages?
The high mechanical values (yield strength/tensile strength) of our grades available make possible considerable reductions in dimensions and wall thicknesses, and regardless of the above they have guaranteed good elongation and ductility values (see table) combined with good weldability.
In the field of mobile hydraulics these potentials for weight savings are becoming more and more important. If the construction is the same this means more safety.
