Martensitic Stainless Steel

Martensitic stainless steels are magnetic and suitable for many applications


Martensitic stainless steel stockholders and suppliers, delivering to the whole of the UK. West Yorkshire Steel are suppliers of a range of sizes and grades in martensitic stainless round bar. Plate, sheet and flat section is available in martensitic grade 420 stainless.

Martensitic grades of stainless steel are supplied in a comprehensive range of sizes and specifications conforming to British, European, American and International standards. Martensitic stainless steel specifications combine high strength with corrosion resistance, though they are less ductile than other stainless steels types. Grades can offer high tensile and yield strengths with the maximum strength and hardness depending upon the carbon content and the heat treatment applied. The effect of heat treatment is similar to plain carbon or low alloy steels except that with the high alloy content martensitic stainless steel grades can be very sensitive to heat treatment variables. Martensitic stainless steels are magnetic and suitable for many applications requiring strength or hardness with corrosion resistance.

We welcome export enquiries for stainless steel. Contact our sales office and consult our shipping policy for further details.

Martensitic stainless steel grades are suitable for heat treatment. Consideration should be given to temperatures, including rate of heating, cooling and soaking times etc. which will vary due to factors such as the shape and size of each martensitic stainless 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 martensitic stainless steel specifications.


Martensitic stainless steel grades are available with BS EN 10204 3.1 mill certificate, please request when placing any orders.


All our martensitic stainless steel grades are supplied in accordance with our ISO 9001 : 2008 registration.
