Why Client Like DIN2391 ST52 Tube For Hydraulic Cylinder

  DIN2391 ST52 Tube material is the most popular use in hydraulic cylinder production due to the better price and good yield and tensile properties. As one of the leading  cylinder honing tubes suppliers and manufacturers, We produce DIN2391 ST52 honed steel tubes and DIN2391 ST52 skived roller burnished tubes with high quality with better prices.  Advantages of Datong DIN2391 ST52 Tubing 1, High precision tolerances; Our DIN2391 ST52  honed steel tube can meet ID tolerance H7, H8, H9, … etc according to the customer’ requirements, and its I.D dimension. 2, Seamless tube with high pressure resistance; We only use seamless cold drawn tubes to produce honed barrels, which means the hydraulic cylinder can work under higher pressure, thus our honed tubes are more reliable for industry applications. 3, High Smooth inside surface; The roughness of our honed pipe is Max Ra 0.4 microns ID finish . 4, Good weldability: The weldability of our honed steel tubing is very good, this is quite helpf

EN10204 Steel Grinding Chrome Rod 42CrMo4+QT

 42CrMo4 is a heat treatable steel which contains at least 0.9%Cr,0.15%Mo as strengthening elements. After quenched and tempered, It obtains high strength, good low-temperature impact toughness with a typical tensile strength of 900 -1200 N/mm2.42CrMo4 steel has better performance than 34CrMo4 steel due to the higher carbon and chromium content.Similar to AISI 4140,only a little difference in Mn,Cr content.This material also has good machinability,good wear-resistance,but the temper brittleness is not obvious,and poor in weldability. CHrome rod 42CrMo4 is mainly used for hydraulic cylinder.The piston rod material 42CrMo4 hardened and hard chrome plated with the material number 1.7225 is suitable for heavy use and is especially wear-resistant thanks to its hardened surface layer with a surface hardness of 56–64 HRC. The Advantages Of our  Hard Chrome Plated Rod 42Crmo4 1.Hard chrome plating means that an especially thick chrome layer is applied after the pre-honing and before finishi
