In this second and final article on the forging of plain-carbon and low-alloy steels, their designations, metallurgical issues and post-forging processing are discussed.
As we indicated in the first article in this series, more forgings are made from the various grades of steel than any other type of metal. Steels have a range of compositions and properties that make them the ideal choice in many critical forging applications. They are also one of the most economical materials in meeting the requirements for numerous components. In the first article, we examined the chemistry, typical applications and some operational issues for forging plain-carbon and low-alloy steels. In this second article, we will discuss metallurgical issues, post-forging processing and typical properties of forged components
