I-Duplex steel S31803 amashubhu angelinye lama-alloys athandwa kakhulu futhi asetshenziswa kabanzi emhlabeni. Baziwa ngamandla abo aphezulu, ukuqina kanye nokumelana nokugqwala. I-Duplex steel S31803 iyinsimbi engagqwali eyiduplex equkethe u-25% we-chromium kanye ne-nickel engu-7%. Inamandla aphezulu kuya esisindweni kanye nezakhiwo ezinhle kakhulu zokumelana nokugqwala uma kuqhathaniswa nezinsimbi ezingenasici ze-austenitic ezifana no-304L no-316L. I-Duplex Steel S31803 Tube inokumelana nokugoba okuhle kakhulu ngenxa yokuqukethwe kwayo kwekhabhoni ephansi, okusiza ukuvikela ukugqwala komgodi.

Amashubhu atholakala ngezindlela ezimbili, angenamthungo futhi ashiselwe. Amashubhu angenamthungo enziwa ngaphandle kokushisela, kuyilapho amashubhu ashiselwe ane-weld ngobude beshubhu. Zombili lezi zinhlobo zinezinzuzo kuye ngezidingo zakho zohlelo lokusebenza, nokho amashubhu angenamthungo asetshenziswa kabanzi ngenxa yamandla awo aphezulu kuya esilinganisweni sesisindo kanye nekhono lokumelana nezinga lokushisa eliphakeme kunamashubhu ashiselwe.
