Heat Treatment

S275 is not ideally suited to hardening, though it can be subjected to limited heat treatment process such as case hardening. When hardening S275 heat treatment temperatures, including rate of heating, cooling and soaking times will vary due to factors such as the shape and size of each component. Other considerations during the heat treatment process include the type of furnace, quenching medium and work piece transfer facilities. Please consult your heat treatment provider for full guidance on heat treatment of S275 carbon steel.


Certification

S275 steel is commonly available with a 3.1b mill certificate, cast and analysis certificate or a certificate of conformity, please request when placing any orders.
