Induction Hardened and Hard Chrome Plated Steel Bar for Shock Absorbers

**Product Specifications** **Company Overview** Suzhou Weipeng Precision Machinery Co., Ltd. is located in Suzhou, a city known for its strong foreign trade and economic development, just a short distance from the international port of Shanghai. Established in 2009, we are a manufacturing company specializing in the production of piston rods and linear shafts. Quality is the lifeblood of our business. Your satisfaction is our top priority. We provide high-quality products such as hard chrome-plated rods, hydraulic piston rods, cylinder piston rods, chromium rods, and induction-hardened rods. Our materials include JIS S45C, SAE1045, and DIN CK45. Our hard chrome-plated piston rods are manufactured with advanced techniques to ensure a surface precision level of F7 and a hardness of at least HV800. This enhances wear resistance and extends the service life of the rods, helping our customers reduce costs. We also conduct corrosion resistance tests in our internal salt spray laboratory, ensuring that the rods meet strict quality standards. The surface heat treatment and hardness reach HRC55±2°, with a hardened depth between 0.5mm and 3mm. After precision milling and hard chrome plating, the coating thickness reaches 20 microns ±10%, significantly improving wear resistance and extending the rod's lifespan. These products are ideal for heavy machinery, construction equipment, and various heavy-duty applications. Suzhou Weipeng's chromed steel bars and tubes are widely used in hydraulic and pneumatic cylinders found in agricultural machinery, lifting equipment, material handling systems, waste collection, and more. **Company Capability**





Below are our main product specifications for your reference. If you have any interest, feel free to contact us. 1. **Hard Chrome Plated Rod** vs. **Induction Hard Chrome Rod** - Place of Origin: Jiangsu, China - Material: JIS S45C, SAE1045, DIN CK45 - Length: 1000-6000mm - Shaft Diameter: 3-120mm - Surface Hardness: HRC58-60 - Chrome Layer Hardness: above HV800 - Chrome Layer Thickness: 15μm ~ 25μm (Customized) - Surface Hardening Depth: 0.8-3mm - Axis Straightness: 0.15mm/1000mm - Roughness: Ra 0.2μm~0.6μm - Precision: G6/F7 **Chrome Plated Steel Bars** Our chrome-plated bars are made from medium carbon cold-finished or hot-rolled steel, typically grade 1045. They are centerless ground, polished, and plated to a minimum thickness of 0.0005", with 0.001" per side. These bars are ideal for use in hydraulic and pneumatic cylinder piston rod applications. **Induction Hardened Chrome Plated Bars** Produced using advanced techniques on JIS S45C, SAE1045, or DIN CK45 steel rods, these bars undergo surface removal, polishing, induction hardening, and then hard chrome plating. The result is a highly impact-resistant bar suitable for tough environments. **Applications** - Hydraulic cylinder rods - Farm equipment machinery - Pin stock for attachments **Honed Tube** - Raw Material: DIN ST52, SAE1020 - Pressure & Temperature Classification: High pressure & temperature piping - Inner Diameter: 40mm-320mm - Outer Diameter: 50-400mm - Thickness: 5-40mm - Length: 7000mm - Straightness: Max 0.5/1000mm - Inside Surface Roughness (Ra): 0.2-0.4um - Tolerance INT: DIN2391 H8 **Cold Drawn Seamless Mechanical Tubing (CDS)** This is a cold-drawn 1020 steel tube, produced from pierced hot-rolled bar stock. It offers better OD and ID uniformity, enhanced machinability, increased strength, and tighter tolerances compared to hot-rolled seamless tubing. **Applications** - 3D printers - Textile machinery - Hydraulic cylinders - Rollers - Structural applications - Truck and automotive parts - Heavy equipment - Agricultural components - Auto and truck axles, suspension parts, shock absorbers - High-speed shafts and rollers - Bearings and spacers, roll cages, and other machined tubular parts Our raw materials come from well-known Chinese brands, ensuring high density and stable quality. Our products are highly appreciated by clients for their competitive pricing and excellent performance. Wish You a Happy New Year! **Applications Include:** - Plastic injection molding machines - Working servos - Construction equipment - Rubber molding machines - Papermaking machines - Printing machines - Refrigeration equipment - Food and chemical machinery - Loading equipment - Fiber spinning equipment - Agricultural equipment - Automobiles, shipbuilding, and more If you're interested in our company, please feel free to contact us: SUZHOU WEIPENG PRECISION MACHINERY CO., LTD ADD: No.98 Changjiang Road, National Hi-Tech District, 215010, Suzhou, P.R.C Tel: 0086-512-68387269 Fax: 0086-512-68387269 http://www.wepauto.com http://www.chromedbar.com
