Lawa ama-stainless steels aqukethe i-chromium ephakeme ngokuqhathaniswa (phakathi kuka-18 no-28%) namanani amaphakathi e-nickel (phakathi kuka-4.5 no-8%). Okuqukethwe kwe-nickel akwanele ukukhiqiza isakhiwo se-austenitic ngokugcwele futhi inhlanganisela ewumphumela yezakhiwo ze-ferritic ne-austenitic ibizwa ngokuthi i-duplex. Izinsimbi eziningi eziyi-duplex ziqukethe i-molybdenum ebangeni lika-2.5 - 4%.

Izakhiwo eziyisisekelo

• Ukumelana okuphezulu nokuqhekeka kokugqwala kwengcindezi
• Ukwanda kokumelana nokuhlasela kwe-ion chloride
• Ukuqina okuphezulu namandla okukhiqiza kunezinsimbi ze-austenitic noma ze-ferritic
• I-weldability enhle nokwakheka

Ukusetshenziswa okuvamile

• Izicelo zasolwandle, ikakhulukazi emazingeni okushisa aphakeme kancane
• Isitshalo sokukhipha usawoti emanzini
• Izishintshi zokushisa
• Isitshalo se-Petrochemical
