General Characteristics

410L/4003 is a weldable ferritic stainless steel with elevated yield strength and resistance to abrasion. Its better corrosion resistance compared to carbon steels enables lower maintenance costs and longer service life.


410L/4003 is a low-chromium structural ferritic stainless steel. Its corrosion resistance is limited in applications with increased corrosiveness. 410L/4003 can, however, replace carbon steel in many structural applications. 


When some discoloration in more aggressive environments is not acceptable, 410L/4003 may be painted. 410L/4003 is available in many product forms and dimensions, often also from stainless steel stockholders.

Mechanical Properties

The mechanical properties of 410L/4003 make it an attractive choice for applications where high strength and stiffness is desired. The engineering properties are on par with carbon steels. 


As opposed to many other ferritic steels it retains its toughness, even when welded, at temperatures below the freezing point. GNEE uses European Standard EN 10088 when applicable. The permitted design values may vary between product forms. The appropriate values are given in the relevant specification.
