070M20 is commonly supplied bright drawn or as rolled condition. If annealing is required heat to 880-910°C then furnace cool.

As it is a low carbon unalloyed steel grade 070M20 is not ideally suited for heat treatment (080M40 or 080M46 may be a better option). If hardening is required heat to a temperature of 880-910°C. Quench in water and then temper.

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 070M20 carbon steel.

070M20 steel is commonly available with a cast and analysis certificate or a certificate of conformity, please request when placing any orders.
