What is the UNE F1140 steel material equivalent to?

 The material UNE F1140 steel belongs to the material group "Quenched And Tempered Steels". The steel material "UNE F1140" has fourteen alternative names. We also have the chemical analysis of UNE F1140 available for you below. F114 is a steel within the UNE standard for unalloyed steels for quenching and tempering . Its equivalence in the UNE standard would be the F-1140. This is a carbon steel for applications in machinery parts with an average resistance of between 70-90 Kg/mm2. This steel has a wide range of uses, parts for agricultural machinery and for the automobile in general: cylinder rods , sleeves, screws, levers, wheel hubs, etc. In F114 steel, surface hardening is recommended in multiple applications. The equivalence of F114 steel in the DIN standard is CK 45.The material "UNE  F1140" contains Chrome, Manganese, Molybdenum, Nickel, Phosphorus, Silicon and Sulfur.  Good resistance material. F114 steel or CK45 steel is weldable (controlled preh...

Requirements and material section of hydraulic cylinder barrel

Image
The required barrel is a key part of hydraulic cylinder , and sometimes the direct acting component of hydraulic cylinder (when piston rod or plunger is fixed); the barrel, end cover and piston (plunger) form a sealed chamber for containing pressure oil and driving the load for acting; thus the barrel has requirements for strength, rigidity and sealing as below:    (1) The barrel should have sufficient strength to prevent permanent deformation under long-term rated operating pressure and short-term dynamic test pressure.    (2) The barrel should have sufficient rigidity to prevent bending caused by lateral force imposed by the piston and reacting force during installation.    (3) Reliable seal: The grade of dimensional tolerance and accuracy of geometric tolerance of cylinder inner surface, piston seal and supporting ring should be designed rationally to ensure reliable seal and reduce wear.    (4) The cylinder barrel...
