The Hardness Of Induction Hardened Bar

 The process of induction hardened bar can enhance the mechanical properties of ferrous and alloy components in a specific part. Typically, the material of doing induction hardening includes CK45, 20MnV6, 4140 and 4340. First, the piston rod will be put into a copper coil, and it’s heated by alternating current. Then, the outer surface of the cylinder piston rod will be heated to a temperature above the transformation range. After that, the piston rod will be tempered immediately to adjust the hardness level. 

The final surface hardness of the induction hardened rod will be HRC 55° ± 2°.The chrome layer hardness is 850 HV0.1. The surface hardness in the induction hardened zone immediately beneath the chrome layer is 55 HRC min. The depth of hardening is between 1.0 and 3.0 mm depending on dimension.

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...
