The Manufacturing Process of ANBAO EN8 Hard Chrome Rod

 EN8 Hard chrome rod is very hot selling in the hydraulic cylinder field, cause this kind of material has good toughness,high tensile strength and good hardness. The high hardness of the EN8 hard chrome rod significantly extends its service life, reducing the need for frequent replacements and thus lowering maintenance costs. ANBAO GROUP very experienced and successful in this kind of steel tube and rod productions.

 
The manufacturing of ANBAO EN8 Chrome Rod is a complex and precise process. It begins with the melting of the raw materials, carefully proportioned according to the desired chemical composition. The molten steel is then cast into ingots, which are subsequently hot rolled to reduce the cross - sectional area and improve the grain structure of the steel.
During the hot - rolling process, the ingots are passed through a series of rolling mills, gradually shaping them into the desired rod form. The temperature and rolling speed are carefully controlled to ensure the proper mechanical properties of the round rod. After hot - rolling, the rod may undergo a heat - treatment process, such as quenching and tempering. Quenching rapidly cools the rod in a suitable medium, usually oil or water, to increase its hardness. Tempering is then carried out to relieve the internal stresses generated during quenching and to adjust the hardness - toughness balance of the material.

Finally, the cylinder rod may be subjected to a hard chrome plating process. Chrome plating not only enhances the appearance of the hydraulic cylinder rod but also provides additional protection against corrosion and wear. The chrome layer forms a dense and hard - wearing surface, further improving the performance of the EN8 Chrome Rod in harsh environments.

How To Choose The Cylinder Barrel Materials

  The  cylinder barrel   in which the piston operates must be made of a high-strength material, usually steel. It must be as light as possible, yet have the proper characteristics for operating under high temperatures. It must be made of a good bearing material and have high tensile strength. The cylinder barrel is made of a steel alloy forging with the inner surface hardened to resist wear of the piston and the piston rings which bear against it. This hardening is usually done by exposing the steel to ammonia or cyanide gas while the steel is very hot. The steel soaks up nitrogen from the gas, which forms iron nitrides on the exposed surface. As a result of this process, the metal is said to be nitrided. This nitriding only penetrates into the barrel surface a few thousands of an inch. As the cylinder barrels wear due to use, they can be repaired by chroming. This is a process that plates chromium on the surface of the cylinder barrel and brings it back to new standard d...

The hard chrome plating process of Anbao cylinder rod

 Hard chrome plating, also known as hard chromed , is a technique of electroplating that applies a thin layer of chromium onto a cylinder piston rod . Chrome plating is used to provide a working surface that requires one or more of the following characteristics: to reduce friction, resist abrasion, or increase corrosion resistance. It is very hard, measuring between 66 to 70 HRC.  Surface defects and roughness are amplified because hard chrome does not have a leveling effect. Friction between a Anbao cylinder rod and its seals, and the resulting wear, has a crucial influence on the efficiency and service life of a hydraulic cylinder . Chrome plating is a cost-effective repair option that can allow salvage of a cylinder rod, cylinder tube , or valve spool instead of replacing it with new. In addition to the cost benefits, chrome plating also creates a hardened wear surface, extending the life of most high wear areas resulting in longer run times between repair or re...
