Thayipha u-347 (UNS S34700) kushubhu Elihlanganisiwe
Incazelo
347 insimbi engagqwali coiled tubing
Uhlobo 347 i-niobium stabilized chromium nickel austenitic insimbi engagqwali enokumelana nokugqwala okufana no-304/304L.Leli banga livamise ukusetshenziswa ebangeni lokushisa elingu-800-1500˚F lapho lizinza ngokumelene nemvula ye-chromium carbide ngokungezwa kwe-niobium, okuholela emvuleni ye-niobium carbides.Uhlobo 347 lunokumelana nokugqwala okuhle kakhulu kwe-intergranular ngemva kokuchayeka kuleli banga lokushisa, futhi leli banga limelana ne-oxidation kufika ku-1500˚F futhi linezindawo eziphakeme zokukhasa nokuqhekeka kwengcindezi kuno-304/304L.Futhi inokuqina okuhle kwezinga lokushisa eliphansi futhi ayiyona i-magnetic esimweni se-annealed.
