  Induction hardened chrome rods are precision-crafted chromium alloys treated with a magnetic induction process. This technology heats the metal surface to extreme temperatures (up to 1,500°C) and rapidly cools it using a quenching medium. The result? A hardened outer layer (5-8mm thick) with exceptional wear resistance, while the core remains ductile for shock absorption. Key Benefits for Manufacturing Induction Hardened Chrome Rods: ✅ Longer Lifespan: Reduce replacement frequency and labor costs. ✅ Superior Strength: Handle heavy loads and repetitive stress without bending or breaking the raw manterials ✅ Corrosion Resistance: Ideal for automotive, aerospace, and marine industries like hydraulic cylinder applications exposed to harsh environments. ✅ Cost Efficiency: Save up to 40% on maintenance over traditional rods. The Induction Hardened Chrome Rods Over Other Solutions? Feature Induction Hardened Chrome Rods Traditional Chrome Plating Durability 3x longer lifespan Pro...

  CK45 Cylinder piston rod is a very important part in hydraulic cylinder working smoothly,hard chrome plating a piece of precision equipment such as a cylinder rod is a painstaking and methodical process. As one of the leading CK45 chrome plated bar suppliers and manufacturers, DTONG   GROUP   has been supplying and exporting CK45 hard chrome bar and hard chrome rod for almost 20 years with high quality & good prices.Imperial sizes & metric sizes available. The Hard Chrome Plating Process: 1. Inspection The  CK45 cylinder chrome rod  is inspected during the initial evaluation to determine the condition prior to the chroming process. An inspector will make note of any signs of corrosion, pitting, marring, damage, cracking or flaking. The presence of any of these conditions will be taken into account during the re-chroming process. 2. Grinding & Stripping Old material on the  hydraulic cylinder rod  must be removed before new chrome can be a...

 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 ...

  304 316   cylinder steel rod  can not be strengthened by heat treatment like Q+T or   induction hardened   , but it can be strengthened by cold working deformation (cold work hardening, deformation strengthening), which will increase the strength and decrease the plasticity. Austenitic SS 304 steel rod has always played the most important role in stainless steel, and its production and usage account for about 70% of the total production and usage of stainless steel cylinder rod. Due to the excellent performance and characteristics of austenitic stainless steel, it has received more and more attention and application. Especially in the manufacturing and production of nuclear power equipment, it is used to manufacture important and critical parts like  cylinder barrels  or hydraulic presses. The most basic alloying elements of austenitic stainless steel are chromium and nickel-chromed. The representative grade is chromium-nickel austenitic stainless st...

 The nickel-chrome plated rod use the technology is the solution to extreme environments with intense corrosion: offshore, marine conditions, wind, solar and aerospace sectors, agriculture, mining industry, oil and gas industry. Steel grades as 20MnV6 or 38MnVS6, having a low carbon content and good weldability, are the most suitable bases for nickel-chrome plated products. It is typical for most steel materials to undergo some type of plating process to cut down corrosion. Chrome plating and nickel plating are two of the most common plating processes used by industrial businesses due to their durability and affordability. Datong Hydraulic as a professional manufacturer of chrome plating tube and rod,we have several years of experience in providing reliable and efficient carbon steel treatment services for any type of business.  Chemical composition: Chemical composition（%） MATERIAL C% Mn% Si% S% P% V% NI% Cr% Mo% Cu% CK45 0.42-0.50 0.50-0.80 0.17-0.37 ≤0.035 ≤0.035   ≤...

As a professional manufacturer of hydraulic cylinder ,we usually will receive the requirements that customers ask chrome layer thickness of the cylinder rod , 20/25/30/50 Micron or customized can available for us. Hydraulic cylinder piston rod chromium plating layer is not thicker, the better, the reasons: 1, chromium coating in the process is reciprocating multiple coating, that is, the single coating amount is about 0.03-0.06, and the coating effect on the substrate surface is better, the secondary coating effect on the already coated surface is not good, easy to produce delamination, off the skin small defects, and the hydraulic system is the most taboo there are such defects; 2, when the coating thickness reaches more than 0.10, the domestic is not good, not can not be done, but is not necessary in the use of special occasions. 3, supplement: plating process can achieve 0.15-0.20 coating thickness; Coating thickness should vary according to the use of different occasions. When the...
