  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.

  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...

  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   ≤...

  4130 steel , otherwise known as chromium molybdenum steel alloy, is made with 0.8 to 1.1% chromium and 0.15 to 0.25% molybdenum as strengthening agents.Its steel properties make it a versatile metal, especially mechanical properties such as high ductility, good weld-ability, and machi-nability. Equivalent standards of 4130 steel include ASTM A1031 Grade 4130, DIN 1.7214,   25CrMo4 , BS 25CrMo4, EN 1.7214, and UNS G41300. APPLICATIONS OF CHROMOLY (4130 STEEL) 4130 steel rods and tubes are very popular with high strength and great weldability.

  CK45 round steel bar   general purpose medium carbon steel delivered in as  hot rolled   condition. It can be further heat treated to achieve specific mechanical properties. The 0.45% carbon content is not favorable for welding. However, it can be weld with appropriate pre and post weld heat treatment. Surface hardness of 57~62 HRC can be achieved with cast hardening to a depth of approximately 1mm. Used for most transmission and motor parts of medium strength. Case hardened parts such as camshafts, gears, rocking levers etc. Simple hand tools and various types of fasteners and fixtures, machinery parts and components with medium stress.
