Steel Properties
1.4410 is a corrosion resistant, austenitic-ferritic super-duplex steel. An austenite/ferrite structure and small grain size provide the material with its hardness, strength, and toughness. The super-duplex steel 1.4410, also known as F53, is used for components where conventional austenite and corrosion-resistant duplex steels (1.4462) fail to fulfil the corrosion requirements.
