Applications
Alloy 347H inowanzoshandiswa pakugadzira michina, iyo inofanirwa kuiswa mubasa pasi pemamiriro ezvinhu ekuora kwakanyanya, uye inowanikwawo kune maindasitiri ekunatsa petroleum.
Corrosion Resistance:
.Inopa kupikisa kwakafanana kune zvakajairika, corrosion yakazara seAlloy 304
.Inoshandiswa kumashandisirwo ayo alloys akadai seAlloy 304 ari panjodzi ye intergranualr corrosion.
.Kazhinji inoshandiswa kune inorema welded midziyo isingagone kuvharwa uye yemidziyo
iyo inoshandiswa pakati pe800 kusvika 150 ° F (427 TO 816 ° C)
.Alloy 347 inosarudzwa pane Alloy 321 kune aqueous uye dzimwe nzvimbo dzakaderera tembiricha.
.Inonyanya kushandiswa munzvimbo dzekushisa kwepamusoro uko kupokana kwekunzwa kwakakosha, zvichizodzivirira intergranualr corrosion pamazinga akaderera.
.Inokonzeresa kushushikana kukoromoka
.Inoratidza oxidation kuramba yakafanana nemamwe ese 18-8 austenitic simbi isina tsvina
