The subject of induction heat treatment is no more complex than the thermal transformation of, say, a tool steel or an alloy steel.

The purpose of tempering is to create a new structure from the as-quenched martensitic structure of a particular steel.

Carburizing has been traditionally accomplished at temperatures in the 1700

The problem of soft spots on surface-treated work such as nitriding, ferritic nitrocarburizing, carbonitriding and carburizing is a very common occurrence in heat treatment today.

The hardness of the high-alloy tool steels in the as-quenched condition does not usually exhibit the full hardness that can be obtained with that steel.

What does it mean when we hear the term “internal oxidation” when carburizing?

It can be concluded that the remaining austenite is soft even though it is saturated with carbon.

Heat-treatment training and the enhancement of knowledge for a heat treater should be an ongoing process.

When steel is carburized in the austenite condition, the austenite is a very stable metallurgical phase.

What effect do the alloying elements have on the resulting spark of the sample?
