Development of Microalloyed Medium Carbon Hot Rolled Bar Products
Abstract:
The application of mlcroalloylng technology in the production of bar products was initially employed by Jones & Laughlin Steel for cold finished bars. These products are available in a variety of grades with guaranteed strength levels. More recently, hot rolled mlcroalloyed bar steels have found acceptance in a. number of applications spanning products with high strength properties produced directly from the bar stock, to air cooled forgings which do not require heat treatment. As Is the case for cold finished bars, mlcroalloyed hot rolled bars can be produced with guaranteed strength properties. These properties are a function of the base composition, the type and amount of microalloylng addition, the bar diameter and thermal practice. This paper will address each of these factors and describe several commercial applications Involving the production of forged parts from mlcroalloyed bar steels
