Abstract:
Distortion resulting from heat treatment has a significant effect upon final component costs. Most of the factors which influence distortion behaviour arise during the machining and heat treatment processes and are therefore outside the control of the steelmaker. One important factor which is under the jurisdiction of the steelmaker is hardenability. Consistent hardenability performance can have a significant effect in reducing the variability in distortion. In a number of instances, it has been shown that the macrostructure and as-cast shape of the steel can also influence distortion. Other downstream processing effects, such as forging, may also be influential in these circumstances. This paper gives examples of some of the experiences of British Steel Engineering Steels, with customers and endusers, and refers to relevant published work.
