Description
Large forging parts are normally manufacturing by open die forging which can produce forgings from a few pounds up to more than 150 tons. So, this method is used when forgings are very large and the parts cannot be made by other processes. The process of open die forging is carried out in large hydraulic presses or power hammers. In this module the applications, processes of fabrication and selection of steel for low hardenability will be explained.
Then, Chromium / Boron steel used in a direct quenching application will be showed.
Finally, the applications and processes of fabrication of large forging will be explained.
What you will learn
- Interpret some alloy steel specifications,
- Select appropriate alloy steel compositions for selected applications;
- Explain how to heat treat alloy steels.
