Carburizing hardening treatment increases the wear resistance and fatigue strength of SCM415 due to the formation of a tough, high-carbon surface layer. This enhances the ability of the material to resist surface pressure and extend the lifespan of parts exposed to harsh environments or stress.

It is particularly useful in applications where the material must withstand extreme conditions over long periods.

15CrMo Steel Has Yield Strength of 415 MPa – Check Forging Temperature of Acero SCM415

The yield strength of 15CrMo steel is 415 MPa, which makes it suitable for use in boilers, pressure vessels, and high-pressure, high-temperature piping systems. Proper control of forging temperature is essential to achieve optimal mechanical properties and microstructure. After forging, the material undergoes heat treatment to enhance its strength, ductility, and hardness.

X30WCRV93KU Grade Has High Rigidity – SCM415 Case Harden Steel Fatigue Strength

Due to its high rigidity, X30WCRV93KU can support heavy loads without deforming. The presence of molybdenum and chromium increases its tensile and yield strength, contributing to its overall rigidity. This makes it suitable for pressure vessels and high-pressure applications.

When SCM415 is case hardened, the surface becomes harder, improving its fatigue resistance. However, proper execution of this process is crucial to avoid any negative impact on the material’s fatigue properties. Manufacturers must ensure precision during this step.
