Ferritic Stainless Steel - an overview ScienceDirect Topics

P.Lambert,in Sustainability of Construction Materials,2009.6.3.1 Ferritic stainless steel.Ferritic stainless steels are magnetic,non-heat-treatable steels that contain 1130% chromium but with little or no nickel.They are typically employed for non-structural applications where there is a requirement for good general corrosion resistance or good stress corrosion resistance (an Exaton 316L Cryo316L Cryo is a filler material for joining austenitic stainless steels,e.g.ASTM 316,316L,as well as 304,304L,for cryogenic applications and meets the requirements of ASME Section VIII,Division 1,UHA 51 ((a) (4) (-a) (-1)) and others.It is used for service temperatures down to -269 welded steel storage tanks longitudinal Charpy V notch impact values#186;C (-452 welded steel storage tanks longitudinal Charpy V notch impact values#186;F),and ferritic or martensitic stainless steels,with maximum 19% Cr.Exaton 316L Cryo316L Cryo is a filler material for joining austenitic stainless steels,e.g.ASTM 316,316L,as well as 304,304L,for cryogenic applications and meets the requirements of ASME Section VIII,Division 1,UHA 51 ((a) (4) (-a) (-1)) and others.It is used for service temperatures down to -269 welded steel storage tanks longitudinal Charpy V notch impact values#186;C (-452 welded steel storage tanks longitudinal Charpy V notch impact values#186;F),and ferritic or martensitic stainless steels,with maximum 19% Cr.
