Carburising and case hardening of 835M15 will give a hard wear resisting surface and a tough core strength to the steel. Surfaces must be free from dirt and grease, and of low sulphur content. Case hardening can be carried out 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.

835M15 case hardening steel is available with BS EN 10204 3.1 mill certificate, please request when placing any orders.
