Part I of this article considered the technology of measuring temperature through the infrared radiation of a heated metal mass and some of the misconceptions and inaccuracies that may be present in or about the process. This article will explore ways to improve accuracy through proper calibration and to take temperature measurements of highly reflective bodies.

The desired metallurgical properties of forgings are derived from having the right billet temperature when they are forged.

Since steels are so widely used, two articles will be devoted to this class of materials. This article will discuss the chemistry, typical applications and some operational forging issues.
