 Normalizing Carbon & Low Alloy Steel

The microstructure of steels in the as-cast condition shows considerable variability both through the section thickness and on a very local scale. This arises due to thermal gradients in the part and segregation of the alloying elements in the steel. The degree of variability in microstructure is dependent upon the alloy composition.

“Accucam is proud to offer this white paper, and to offer solutions to our customers based on a foundation of industry knowledge and experience. We look forward to working with you on your next project. The success of our customers product is our goal!”

“We hope you find this a useful and informative tech-note to help shed some light on the often misunderstood ‘art’ of heat treatment. When you partner with Accucam for your development and production needs, you can be assured that we will apply the best of our technology and manufacturing know-how to provide a quality product at the lowest cost for your application.”
– Clayton Sloss, Director of Engineering

The behaviour of the steel during heat treatment, and the resulting structure and properties, is dependent upon the initial microstructure, the alloy chemistry and the heat treatment schedule.

If there is significant variability in chemistry and structure throughout the casting, on both macro and micro/local scales, the resulting properties achieved in the steel through heat treatment will vary with location. This can also result in additional transformational residual stresses which can promote cracking.
