chrome plated shaft VS Stainless Steel Shaft

Image
  AISI 1045  chrome plated shaft  is cold drawn, precision ground and polished shafting with a seam free surface finish of RMS 25 max. The bars are then hard chrome plated by electrolytically deposited layer of chromium metal on the surface. This hard chromed surface confers the important properties of corrosion resistance and wear resistance; it is also very smooth and therefore has a low coefficient of friction. Not least of all, it has an attractive and durable decorative appearance. Stainless Steel is an iron-based metal alloy, with added elements including chromium, nickel, silicon and carbon. These elements are mixed into the base material itself, and are present throughout the entire structure of the shafts.   The surface of the Stainless Steel is then finely polished to a mirror finish. Because the Stainless properties are evident throughout the entire bar, any damage or scratches can simply be re-polished to expose the fresh new material underneath. As a pro...

THE KEY BENEFITS OF SS304 HONED BARREL

  Honed Barrel SS304 is a very common  material for hydraulic cylinder manufacturers , 304 stainless steel is the most widely available of all stainless steels in the wire mesh industry, aside from the countless combinations of mesh opening sizes and diameter wire available both from stock and through manufacturing. 304 SS exhibits many benefits and is largely considered the standard of the industry. 304 SS has excellent corrosion resistance in a wide range of environments. And it is used in a wide range of applications. ADVANTAGES OF DATONG’S Honed Barrel SS304 1, High precision tolerances; Our stainless steel honed 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 stainless steel honed pipes, which means our honed tubing can work under higher pressure, thus our honed pipes are more reliable for hydraulic cylinder applic...

The Manufacturing Process Of Inside Precision Skiving Tubes

Image
  Precision Skiving Tubes   are made from heat treatment of cold drawn, and then skived and roller burnished. They usually can be used for manufacturing   custom hydraulic cylinder   especially for big bore size.Skiving and roller burnishing is finishing method that does not remove the material in the form of chips, but rather transforms the surface layer. Precision skiving tubes from DATONG HYDRAULIC are made of ST52.3 BK+S (E355SR) material – with standard of DIN2391, low-carbon steel grade with guaranteed weldability.  The manufacturing Process Of Precision Skived roller burnished tubes Seamless hot rolled hollows are obtained with controlled concentricity on an  rolling line and then drawn to precision tubes with significant cross-section reduction improving the geometry and strengthens of the tubes. The cold deformed tubes are then Inside skived and roller burnished (SRB) using state of the art equipment and tools supplied by well-known producers with ...
