Limaraka tsena li fana ka palo e ts'oanang ea khanyetso ea kutu joalo ka limaraka tse tsitsitseng tsa chromium.E na le bokhoni ba ho hanyetsa ho bola ka kakaretso le sebakeng sa heno.Ka kakaretso, ke boemo bo tsitsitseng ba SS bo fanang ka khanyetso e ntle ea ho bola ha intergranular ha ba pepesehetse mocheso o phahameng.E hanana le chromium carbide range of precipitation(sensitization) mochesong oa 427 ho isa ho 816 degree C. E tsitsitse khahlano le chromium carbide formation.
Alloy 347/ 347H e ka hlaseloa habonolo ke ho phatloha ha corrosion (SSC) libakeng tsa halides.Sena se bakoa ke litaba tsa eona tsa nickel.E na le likarolo tsa alloying e e lumellang hore e sebelisoe libakeng tse nang le likoti le likoti.E bonts'a khanyetso ea oxidation ha e bapisoa le limaraka tse tloaelehileng.Lintho tse lakatsehang tsa 'mele li tsoa ts'ebetsong ea phekolo ea mocheso.Hangata alloy 347 ha e na matla a makenete maemong a annealed, leha ho le joalo, e fetoha makenete ha e pepesetsoa ts'ebetso e batang. - Lintlha tsa ho theha
