Inkcazo emfutshane:

Iityhubhu zeNtsimbi Engagqwaliyo ze-904L. I-UNS N08904, eyaziwa ngokuba yi-904L, yintsimbi engagqwaliyo ye-austenitic ene-carbon ephantsi esetyenziswa kakhulu kwiindawo apho iipropati zokugqwala ze-AISI 316L kunye ne-AISI 317L zinganeliyo. Le austenitic ene-alloy ephezulu imelana kakhulu nokuhlaselwa yi-sulfuric acid exutyiweyo, i-phosphoric acid kunye ne-acetic acid. Imelana nokugalelwa kwizisombululo ze-chloride engathathi cala. Ukuxhathisa kwayo ukuqhekeka kokugqwala kokuxinezeleka kwezinye ii-chloride ezishushu kungaphezulu kakhulu kune-nickel austenites ezisezantsi. Le ntsimbi inokwakheka okuhle kunye nokudityaniswa. Le nto ikhona kuyo yonke imigangatho eqhelekileyo efana ne-ASTM kunye ne-EN, nangona kunjalo kukho umahluko othile. Ukuxinezeleka koyilo ukuya kuthi ga kwi-370°C kufakiwe kwi-ASME II.
