WHAT IS THE GENERAL THICKNESS OF CHROME PLATING FOR HYDRAULIC CYLINDER RODS?

 As we all know, the thickness of the chrome plating much related to the working life of the industry hydraulic cylinder ,As a professional manufacturer of hydraulic cylinder ,we usually will receive the requirements that customers ask chrome layer thickness of the hydraulic 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;

hydraulic cylinder rods


Coating thickness should vary according to the use of different occasions. When the mechanical load is light and general protection, the thickness is l0 ~ 20μm; When the sliding load and the pressure is not too large, the thickness is 20 ~ 25μm; When the mechanical stress is large and the corrosion resistance is strong, the thickness is as high as l50 ~ 300μm; For the piston rod, this thickness is generally enough for hard chrome plating, even taking into account other aspects of the requirements, although the proposed thickness can be achieved, but for the outer circle, the chromium layer is a little thick, the coating binding force is higher, and the plating is more difficult. For the piston rod exposed to the outside, the chromium layer that is too thick is not as resistant to bumping as the thinner chromium layer.

40CR ALLOY STEEL SPECIFICATION

  40Cr steel  is a kind of Chinese GB standard alloy steel for engineering and machinery purpose, and one of the most widely used steel grades. For 40Cr material hardness, specifications and equivalent, please see the table below. After quenching and tempering treatment, 40Cr steel has good comprehensive mechanical properties, low temperature impact toughness, low notch sensitivity, good hardenability, and high fatigue strength in cold oil. When water cooling, the complicated shape of the parts is prone to cracks, the cold bending plasticity is medium, and the cutting workability after normalizing is good, but the weldability is poor, should be preheated before welding, and is generally used in the state of quenching and tempering. DATASHEET & SPECIFICATION The tables below list 40Cr alloy steel datasheet and specification including chemical composition, properties and heat treatment, etc. 40CR STEEL CHEMICAL COMPOSITION   Chemical Composition (%) Grade C % Si Mn Cr 40Cr 0.37 – 0.4

How to deal with the scratch on the surface of hydraulic cylinder barrel

Image
As we all know,In the process of using the  hydraulic cylinder , the hydraulic cylinder barrel will be damaged,it is common that there will be scratch on the surface of the  honed tube , some customers will ignore these scratches, this to us is not responsible for the cylinder, when a small scratches in the cylinder,we usually take some tips to deal with them. 1.First,  to clean up the oil on the surface of our hydraulic cylinder barrel, then we will use the grinder machine to the surface treatment of the scratched part of our cylinder, at this time we have to grind the surface of the cylinder wall out of swallowtail groove. Although we have cleaned our cylinder at the beginning, at this time we need to clean the cylinder barrel further. At this time, we use anhydrous ethanol to clean the surface of the scratch repair of honed cylinder barrel. 2. We usually use special  repairing adhesive  to solve the scratches on the surface of  hydraulic cylinder barrel ,  before using it, we need t

What is Hydraulic Ram Cylinder?

Image
  Hydraulic ram cylinders   are typically used to give vertical motion, including lifting loads in a vertical direction. Such a cylinder is also used to provide the motion in a horizontal direction but needs attention and suitable guides to guide the motion. Single-acting hydraulic cylinders that have no pistons but have large  cylinder rod s are called rams. These rams operate exactly like the conventional single acting hydraulic  cylinders. However, they use large diameter rods in place of pistons and piston seals in their designs. Thus, in place of pistons, rams have high-pressure cap-end ports. They also do not have any low-pressure rod-end ports. Rams are generally cheaper than their conventional single-acting cylinders counterparts.
