WHAT IS THE HEAR TREATMENT FOR CHROME PLATED ROD

 Chrome plated rod is a very important material as cylinder rod for hydraulic cylinders and pneumatic cylinders. Usually we use steel round bar to produce hard chrome rod, materials like Ck45 1045 4140 42CrMo4 SS304/316 to keep the cylinder rod good working performace.

The heat treatment process is also very important to chrome cylinder rod. Normally the chrome plated bars are supplied with a certain heat treatment process. The heat treatment will provide the chrome plated rod with higher strength, high hardness and lower residual Stress. There are 3 main heat treatment process for chrome plated steel bar as below.

  • Quenching and tempering heat treatment: Q&T treatment is the most popular heat treatment for hard chrome plated rods, most of the materials of chromed rods such as CK45, SAE1045, 4140, 42Crmo4 can be Q&T heat treated.
  • Induction hardened heat treatment
    Induction hardened heat treatment usually is applied to get higher hardnen for the piston rods, chrome plated bar with this kind of heat treatment is known as induction hardened chrome rod.
  • Q&T treatment and then induction hardened

The heat treatment is applied before chrome plating, and some customers maybe not require the steel rods heat treated for some low requirement applications, in this case they can save some more cost.

As a professional chrome plated rod factory, Wuxi YUTONG has various types of chrome rods/bars/shafts we have in stocks are standard hard chrome rods and induction hardened chromed rods . Other types of steel rods such as nickel-chrome rod and hollow chrome rods are also available on request.

THE APPLICATION OF DIN2391 ST52.4 PRECISION HYDRAULIC STEEL TUBE

图片
  ST52.4 Hydraulic steel tubes   are tubes made in accordance to DIN 2391 / DIN 2445. ST52.4 is a high grade steel material, it can withstand higher working pressure with same tube OD size compare to ST37.4 material.  The delivery condition for grade ST52.4 tubes are in NBK finishing, which is normalized, phospated, and oiled inside and outside. Hydraulic tubes ST52.4 are measured by Outer Diameter (OD) and in varies tube thickness (THK). Difference of OD and tube thickness lead to different working pressure. ST52.4 Precision Hydraulic tube  is used in a variety of industries, including oil and gas, waterjet cutting, food processing, petrochemical/chemical, and many others for fluid handling.   Oil and gas:  The oil and gas industry has many uses for high pressure stainless steel tubing. In the field, high-pressure tubing is used for down-hole control systems, hydraulic and pneumatic piping, chemical injection modules, vacuum systems, and much more. Chemica...
