Austenite Stainless Steel
Alloy e phahameng ea mocheso
◆904L e ke ke ea rarolla feela ho senyeha ha kakaretso ea sulfuric acid, phosphoric acid le acetic acid, empa hape ho rarolla mathata a chloride pitting corrosion, crevice corrosion le stress corrosion.
◆253Ma (S30815) ke tšepe e hloekileng ea austenitic e sa jeleng paate e thibelang mocheso e entsoeng motheong oa 21Cr-11Ni tšepe e sa hloekang ka N alloying le ho eketsa ntho e sa tloaelehang ea lefatše Ce. E sebelisoa haholo-holo tlhahiso ea lipoleiti.
◆254SMo (F44 / S31254) ke tšepe e sa hloekang ea austenitic e phahameng haholo, e atisang ho sebelisoa e le sebaka sa lisebelisoa tse phahameng tsa nickel le titanium. E sebelisoa haholo lits'ebetsong tse ngata tse senyang joalo ka lits'ebetso tsa lik'hemik'hale le petrochemical le tharollo ea chloride.
◆Al-6XN(N08367) e loketse lipompo, li-valve, li-flange le tsamaiso ea liphaephe tsa oli le khase, lik'hemik'hale le matla a motlakase.
