Abstract

This chapter starts by providing a brief historical review of the discovery, development and implementation of high strength low alloyed (HSLA) steels. Since their introduction HSLA steels have been one of the most disruptive technologies in the steel industry. Their worldwide use in the automotive, oil, gas, and other industries represents both a challenge and an opportunity to improve the performance of these steels. The chapter continues by discussing the different grades of HSLA steels used in the automotive industry, their important mechanical properties, and provides some examples of applications. It then explains the role of alloy composition, processing and transformation behavior on the structure–property relationship of HSLA steels. The end provides a review of the laws and models governing various metallurgical phenomena and prediction of properties in HSLA steels.
