  34CrMo4 seamless steel tube is an alloy structural steel with high endurance and creep strength at high temperatures. It's mainly used for cylinder manufacturing or structural parts working under high loads such as transmission parts of vehicles and engines; turbine-generator rotor, spindle, heavy load drive shaft, large section parts, locomotive traction gear, supercharger transmission gear, rear shaft, connecting rod and spring clamp with great load, can also be used for the oil drilling pipe joints and fishing tools below 2000m. However, its poor weldability requires preheating before welding, heat treatment after welding and stress elimination. It is generally used after quenching and tempering, and used after high and medium frequency surface quenching or quenching and low and medium temperature tempering. 34CrMo4 Steel gas cylinders are manufacturing special steel cylinders. Requirements are usually smaller carbon content, strictly control the sulphur and phosphorus cont

25HM steel, which is a Polish equivalent of 25CrMo4, is alternately classified as structural steel for heat improvement and as a boiler steel designed to work at elevated temperatures. It exhibits very good strength properties, high ductility, weldability and good hardenability. Compared to the 35HM and 34CrMo4 grades, after heat treatment it has slightly worse strengths, but it makes up for the lower properties with much better ductility. 25HM achieves best durability values at dimensions up to 65mm after hardening in water, while after hardening in oil at dimensions and thicknesses up to 40mm. It is most often found in a heat-treated or softened state - less commonly in the normalized state. For use in high temperature applications - the power industry - this steel is used in the production of parts working at 450 - 530 ℃, which exhibit creep resistance: flanges and welds for pipes, covers, nuts, heavy-duty screws, turbine rotors, turbine blades, toothed shafts, cylinder rods ,s

  ST52 BK+S honed tube is shaped in the form of a cylinder barrel and is attached to hydraulic fluids allowing for movement of fluids in and out of the grade. These tubes cover the specification of ;ST52 steel cold drawn tube ;and precision steel tubes of seamless types. ST52 Honed Cylinder Tube is part of a hydraulic cylinder that has a smooth surface finish on the interior of the bore. DIN 2391 ST52 nbk is a precision mild or low carbon grade. The DIN 2391 ST52 NBK Tube ;is capable of withstanding high temperatures. These tubes are produced in the normalized condition in controlled setups. The ST52 S355 Annealed Tube ;is annealed above the upper transformation point. The annealed tubes showcase good tolerance to reducing environments. The Specifications Of ST52 BK+S Honed Tube Material : ST52,ST52.3 Delivery Condition : BK, BK+S, GBK, NBK ID Size  : 20mm – 1500mm Length : max 16m Type : Seamless, Hot Rolled, Cold Rolled, Cold Drawn Straightness : ≤ 0.5/1000 Roughness : 0.

  Anbao Hydraulic honed tube is also known as hydraulic cylinder tube. it is usually made of cold drawn seamless tubes or DOM tubes, as hydraulic cylinder tubes are usually used to manufacture hydraulic cylinders body, so it is called hydraulic cylinder barrel commonly.
