Oil and gas steel grades are generally supplied quenched and tempered. The alloy steel grades are characterised by the inclusion of elements such as chromium, nickel, molybdenum and vanadium within their specifications.

Below we list our range of oil and gas alloy steels. If you do no find the specification you require on our web site please contact our experienced sales team who may be able to assist you with your enquiry.


The grades are typically supplied heat treated to a defined Rockwell hardness. If further heat treatment is required  temperatures, including rate of heating, cooling and soaking times etc. will vary due to factors such as the shape and size of each 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 oil and gas steel grades.

We recommend that you contact your welding consumables supplier who should provide you full assistance and information on welding oil and gas steel grades.

Oil and gas 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.
