BS970 steel grades are commonly carbon and alloy steels which can be heat treated to achieve a wide range of tensile strengths and mechanical properties. Some stainless steel specifications are also referenced in BS970. Although still commonly produced to BS970 designations most carbon and alloy grades have officially been superseded by new BS EN steel standards such as BS EN 10083, BS EN 10088 and BS EN 10277.

500-999 Alloy steel grades
The 4th character of a BS970 grade is a letter which indicates the following,
A The steel is supplied to composition only
H The steel is suitable for heat treatment (though this applies to most specifications)
M Mechanical properties are available with the steel

|Typical Mechanical Properties*||
For guidance only we list below typical mechanical properties achievable when heat treating BS970 specifications. Please refer to the full BS970 specification of each grade for further information.
Heat treatment temperatures, including rate of heating, cooling and soaking times will vary due to factors such as the shape and size of each BS970 steel 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 BS970 steel.
We recommend that you contact your welding consumables supplier who should provide you full assistance and information on welding steel grades.
BS970 steel specifications are commonly available with a cast and analysis certificate or a BS EN 10204 3.1 mill certificate, please request when placing any orders.
