Corrosion resistance
Uniform corrosion Uniform corrosion is characterised by a uniform attack on the steel surface that has come into contact with a corrosive medium. The corrosion resistance is generally considered good if the corrosion attack is less than 0,1 mm/year. Due to the high content of chromium 405 offers excellent corrosion resistance in many media.
Intercrystalline corrosion
The microstructure and the low carbon content gives 405 very good resistance to intercrystalline corrosion. The composition of the steel ensures that austenite is reformed in the heat-affected zone after welding. The risk of undesirable precipitation of carbides and nitrides in the grain boundaries is thus minimized.
