Case hardening will give a hard wear resistant surface and a tough core strength to the 665M17. Surfaces must be free from dirt and grease, and of low sulphur content. Case hardening can be performed in salt baths with selected content depending on the type of salt and the depth of penetration required. Other considerations during the heat treatment process include the type of furnace, quenching medium and work piece transfer facilities. Time, temperatures and salt selection will be advised by your heat treatment provider.

Heat treatment temperatures, including rate of heating, cooling and soaking times will vary due to factors such as the shape and size of each 665M17 steel component. Other considerations during the heat treatment process include the type of furnace, quenching medium and the work piece transfer facilities.
