Below is the chemical composition & mechanical properties of the 4140 chrome plated bars.

1.Carbon steel balances durability, hardness, and wear resistance using formability, weldability, and durability;

2.Our chrome plated rod are manufactured with high dimension precision, tolerance can be ISO f7, f8 or g6, upon request. Which ensures the precision of the hydraulic cylinder or the machine.

2. Chrome plating provides corrosion resistance along with an Extremely reflective look

3. High precision tolerances, which ensures when used to make hydraulic piston rod, it can fit the cylinder precisely.

4.Flexible order quantity: we accept small quantity orders

5. Good Hardness: the surface hardness attaining HV850 minimal and upward, which not only help improve wear resistance but also help extend the life span of these chrome plated rods, thereby helping the consumer save the cost.

6.Strictly quality control: All the chrome rods will be inspected before delivery. The inspections including: Chemical Analysis Test, Tensile Test, Dimension Inspection, Roughness Testing, Chrome plated thickness test and other tests according to standards and cusotmer’s requirements.

1.Extensive production experience: more than 20 years manufacturing experience for honed tube and chrome plated rod, in Australia, Peru, Chile, Thailand, Singapore,Columbia,Canada, Mexico,US,Saudi Arabia,Brazil, India, Iran, Indonesia and other countries have long-term buyers.

2.Advanced production equipment: cold drawing machine, honing machine, skiving & roller burnishing machine, straightening machine, polishing machine, heat treatment furnace, grinding machine, etc. We have professional technicians do regular scheduled maintenance on these machines to guarantee them work well.

3.High quality raw material: our raw material mainly from some famous steel mills, such as TPCO, BAO STEEL, SHA STEEL, which are best and largest raw material manufacturer in China.

4.High precision: Honed Tube, inside surface roughness 02-0.4 um, straightness max 0.5/1000, strict tolerance DIN2391 H8. Skived & Roller Burnished Tube, inside surface roughness under 0.2 um, straightness max 0.2/1000, strict tolerance DIN2391 H8. Chrome Plated Rod, chrome layer 10 micron to 100 micron, strict tolerance ISO f7.

5.Strict quality control: we have professional in-house QC to inspect all products. We will do Chemical Composition Test, Mechanical Property Test, Dimension Inspect, Roughness Test, Chrome Layer Test and other tests in need before delivery.

6.Safe packing: an-rust oil on tubes and rods before delivery. Plastic caps on both ends to protect tube inside surface. Then be packed with seaworthy package or in wooden case.
