Isishwankathelo sePipe yeNtsimbi engaGciniyo ye-904L

Intsimbi engagqwaliyo ye-904L iqulathe umxholo we-chromium, nickel, molybdenum kunye nobhedu, ezi zinto zinika uhlobo lwentsimbi engagqwaliyo ye-904L iipropati ezintle zokumelana nokugqwala kwi-sulfuric acid enyibilikisiweyo ngenxa yokongezwa kobhedu, i-904L isetyenziswa kakhulu kwindawo enoxinzelelo oluphezulu kunye nokugqwala apho i-316L kunye ne-317L zingasebenzi kakuhle. I-904L inokwakheka okuphezulu kwe-nickel kunye nomxholo ophantsi wekhabhoni, i-alloy yobhedu eyongezayo iphucula ukumelana kwayo nokugqwala, i-"L" kwi-904L imele ikhabhoni ephantsi, yintsimbi engagqwaliyo yeSuper Austenitic eqhelekileyo, iiklasi ezifanayo ziyi-DIN 1.4539 kunye ne-UNS N08904, 904L ineempawu ezingcono kunezinye iintsimbi ezingagqwaliyo ze-austenitic.

Iipropati zePipe yeNtsimbi Engagqwaliyo ezingama-904L

l Ukumelana okugqwesileyo nokuqhekeka koxinzelelo ngenxa yokuba kukho inani elikhulu le-nickel.

l Ukugqwala kwe-pitting kunye ne-crevice, ukumelana nokugqwala phakathi kwe-granular.

Ibanga le-904L alixhathisi kakhulu kwi-nitric acid.

l Ukwakheka kakuhle, ukuqina kunye nokudityaniswa kakuhle, ngenxa yokwakheka kwekhabhoni ephantsi, ingadityaniswa kusetyenziswa nayiphi na indlela eqhelekileyo, i-904L ayinakuqiniswa ngonyango lobushushu.

l Ayinamagnethi, i-904L yintsimbi engagqwaliyo yase-Austenitic, ngoko ke i-904L ineempawu zesakhiwo sase-Austenitic.

Ukumelana nobushushu, iintsimbi ezingenasici zebanga le-904L zibonelela ngokumelana okuhle kwe-oxidation. Nangona kunjalo, uzinzo lwesakhiwo sale nqanaba luyawa xa amaqondo obushushu aphezulu, ngakumbi ngaphezulu kwama-400°C.

Unyango lobushushu, iintsimbi ezingenasici zebanga le-904L zingalungiswa ngobushushu kwi-1090 ukuya kwi-1175°C, emva koko zipholiswe ngokukhawuleza. Unyango lobushushu lufanelekile ekuqiniseni la manqanaba.
