Jul 09, 2018 · Thanks to Thomas Busch for becoming a Knife Steel Nerds Patreon supporter! Misc. updateI have added a set of supporting micrographs to the introduction to Austenitizing steel. Tempered Martensite To begin describing what bainite is it makes sense to start with martensite first. To form martensite we heat up the steel to high temperature


Detailed

Mar 13, 2018 · A very fast cool produces a total martensite grain structure, making a product high in strength but not ductile. The tempering process is an essential stage in heat treatment, especially in very fast cooling, as it brings back ductility. Before we can start the quenching process we need to heat the steel to a high heat.
