Heat Treatment Equipment Manufacturer, Pyromaître Inc.
Pyromaître’s blog aims to present aspects, but also the metallurgical issues that Pyromaître’s specialists encounter during its daily activities. It likewise has the goal to stimulate exchanges and questions on various spheres of the metallurgical field. Sometimes, you will find basic texts some others will be more technical, but all to generate ideas and development tracks. Comment, share it and make it live!

One of the challenges we face when analyzing steel parts such as springs is their complex geometrical configurations. It is therefore difficult, dare I say impossible in the case of springs, to directly assess the latter and measure their hardness. In the...read more
The most commonly used quenching practice involves oil, which is not as dramatic as quenching in water, especially when the steel is strongly carbon-based. Choosing the right tempering process guarantees optimal performance and a longer service life.read more
This blog is not reserved for confirmed metallurgists, although some may have difficulty explaining steel tempering physical process in layman’s terms.read more
Many spring manufacturers produce their parts by applying strong pressure to wind steel wire under ambient temperature to obtain the desired functional forms. Following this step, however, the spring accumulates too much internal stress, which may weaken...read more
For an industrial oven manufacturer, the toughest challenge is obviously making sure that the heat is evenly distributed. It would be wrong to think that this is better achieved by batch ovens than by conveyor belt ovens. The laws of physics being infallible, many...read more
Manufacturing an industrial oven does not require understanding the subtleties of quantum physics! My guess is that some people in our industry still believe that the mechanical design of an industrial oven basically consists of a box made out of sheet metal and some...read more
Cited in every reference material on the subject, Edgar Bain, between the two World Wars, wrote the book on modern metallurgy. His works describing the many heat treatment processes (particularly tempering and stress relieving) remain relevant to this day...read more
The processes involved in steel quenching and tempering are as old as time. For the last 3000 years, we’ve known that rapid quenching of a red hot sickle blade in whale oil improves its mechanical properties, which nevertheless remain weak upon usage, unless the blade...read more
The auto part construction industry is booming and constantly evolving. Because production parameters for these types of parts call for increasingly advanced technology, our processes must be continuously optimised to the max to maintain our pole position ahead of the...read more
To understand the underlying principles of our heat treatment processes, please read the relevant documentation on the subject in the Customer Reports section of our website. Allow me to introduce the fundamental principles supporting our innovative approach, namely,...read more
