What is stainless magnetic steel used for?

Magnetic stainless steels are used wherever the magnetic property or the increased thermal conductivity is desired, or where these characteristics are not problematic. Martensitic steel is used when additional high strength and hardness are required, as in the production of knives or tools.

Stainless magnetic steel is used for applications including the following:

Exhaust systems, solenoid valves, electric injection, magnetic sensors in the automotive industry
Cookware for induction cookers
Valves and turbine parts in power plants
Knife gate valves, ball gate valves, check valves and shut-off valves in water management, the oil and natural gas industry

What are the properties of stainless magnetic steel?

The characteristics of magnetic stainless steel vary depending on the microstructure.

Ferritic steel

Steel with this structure is magnetic and, depending on the chromium content, inert or resistant to corrosion. It can be welded to a limited degree, because it becomes brittle when exposed to heat for an extended period of time. Ferritic steel can only be cold formed.

Martensitic steel

This steel is also magnetic, depending on the carbon content. It can be hardened through heat treatment and can reach high hardness values depending on its composition. Martensitic steel is resistant to corrosion, although its increased carbon content makes this property less distinct than in other grades of steel. Welding is only possible to a very limited extent.

Austenitic steel

These steels are not (or are only weakly) magnetic. You can find more information on this type of steel on our standard stainless steel page.

What is stainless magnetic steel made of?

Like other stainless steels, stainless magnetic steel consists of an iron-chromium alloy and is also known as chrome steel. Different grades are created by varying the chromium content and adding other alloying elements. Whether a steel is magnetic or not is determined by its structure.

Ferritic stainless steels contain a high chromium and low carbon content. The proportion of nickel is very low and often even non-existent. The chromium content varies and other elements such as niobium, titanium or molybdenum may be added, depending on the desired property.

Martensitic stainless steel contains a slightly lower chromium content than ferritic grades. Martensite is formed by the rapid cooling of austenite. Martensitic steel is magnetic and frequently contains other alloying elements such as vanadium or molybdenum.
