  6. MODIFYING THE MICROSTRUCTURE AND PROPERTY OF

    30CrMnSi steel quenched at 830 and then tempered at 420 which reaches about 43.7 J/cm2. The subcritical austenite inverse transformation quenching improves the toughness of 30CrMnSi steel, which is favorable to prevent brittle fracture of link ring. Figure 1.

  7. The properties and application of bi-metal hot-forging die ...

    The impact toughness of 4Cr2NiMoV is twice that of 5CrMnMo, whilst the impact toughness of 30CrMnMo is twice that of 5CrMnMo. It is obvious that using 30CrMnSi as the swallow-tail material can avoid the early fracture of the swallow-tails. The mechanical properties of the three kinds of steel with typical heat treatment are shown in Table 3.

    As seen in Fig. 3, for each test a tungsten alloy rod and a 30CrMnSi steel tube were assembled coaxially with a distance of 3.5 mm. The TNT explosive was fixed between the 30CrMnSi steel tube and the PVC casing. Similarly, the casing was coaxial with the 30CrMnSi steel tube and the tungsten alloy rod.

  9. Microstructure and mechanical performance of depositing ...

    The 30CrMnSi steel plate with thickness of 3.0 mm was machined to dimensions of 200 mm × 60 mm. The CuSi 3 welding wire with the diameter of 1.2 mm was employed as the deposited metal. The chemical compositions of the materials are listed in Table 1 and the optimal welding parameters are listed in Table 2. Before welding, the oxide films were 30crmnsi steelSome results are removed in response to a notice of local law requirement. For more information, please see here.

  11. The Importance of Normalizing - Heat Treat Doctor.com

    The normalizing of steel (Fig. 2) is carried out by heating ap-proximately 100°F (38°F) above the upper critical temperature (Ac 3 or Acm) followed by cooling in air to room temperature, or at no greater than one-bar pressure using nitrogen if the process is being run in a vacuum furnace. Normalizing is often considered from both a thermal and a

    Through adding different amounts of rare earth into the crack sensitive 30CrMnSi steel samples used in investment casting, the cracking tendency of the steel was evaluated and the optimum amount of rare earth addition was obtained. The results show that the cracking susceptibility decreases with the increase of the amount of rare earth added.

  14. Study on the Interface Diffusion Bonding of the Copper ...

    The copper alloy/30CrMnSi steel bi-metal composite materials were prepared by the interface diffusion bonding method. The diffusion of elements close to the bonding interface was studied and the formation and growth mechanism of dissolution layer were discussed as well. The results showed that a diffusion transition layer could be formed with the different widths for copper alloy/30CrMnSi 30crmnsi steel

  15. Study on weldability window and interface morphology of ...

    The results showed that 30CrMnSi steel tubes and tungsten alloy rods could be successfully welded together. The welding interfaces of composite rods obtained under different explosive loads had different morphological characteristics. With the increase in the explosive load, the welding interface transforms from a straight interface to a 30crmnsi steel
