Ukukhetha ithuluzi elifanele lensimbi kungenye yezinqumo ezibaluleke kakhulu ekwakhiweni nasekusebenzeni kwezikhunta kanye nezindwangu ezisetshenziswa emisebenzini yokushisa okuphezulu njengokubumba, ukuhlanganisa, kanye nokukhipha. Phakathi kwamazinga ahlukahlukene atholakalayo,I-AISI H12futhiI-AISI H13yizinketho ezimbili ezithandwa kakhulu emndenini wensimbi yamathuluzi okusebenza ashisayo.
Zombili izinsimbi zenzelwe ukumelana nokushisa okukhulu, amandla, nokuqina, kodwa zinezici ezihlukile ezenza ngayinye ifanelekele ukusetshenziswa okuthile. Kulesi sihloko,I-SAKYSTEELihlaziya umehluko obalulekile phakathi kwe-AISI H12 ne-H13, ikusize wenze ukukhetha okufanele ngezidingo zakho zokukhiqiza isikhunta kanye namathuluzi.
1. Isingeniso: Ukubaluleka Kokukhetha Insimbi Efanele Yokusebenza Eshisayo
Izinsimbi zamathuluzi okusebenza ashisayo zenzelwe ukugcina amandla omshini kanye nokuqina ngisho nangaphansi kwezimo ezinzima zokushisa okuphezulu kanye nomthwalo wokushisa ojikelezayo. Ezimbonini ezifanaukuphonsa ngodayi, ukwakhiwa okushisayo, futhiukukhipha, ukukhetha okungalungile kwezinto kungaholela ekuqhekekeni, ekugugeni ngaphambi kwesikhathi, noma ekuphazamisekeni kobukhulu—okuholela ekungasebenzini isikhathi esiningi kanye nokwehluleka kwesikhunta.
Ngakho-ke, ukuqondaumehluko phakathi kwe-AISI H12 ne-H13kubalulekile ekufinyeleleni ibhalansi engcono kakhulu phakathi kokuqina, ukumelana nokuguguleka, kanye nokusebenza kokukhathala kokushisa.
2. Ukubuka konke kwe-AISI H12 kanye ne-AISI H13
KokubiliI-AISI H12futhiI-AISI H13Ziyingxenye yochungechunge lwezinsimbi zamathuluzi okusebenza ashisayo ze-AISI H, okuyizinsimbi ezisekelwe ku-chromium ezaziwa ngekhono lazo lokumelana nokuthamba emazingeni okushisa aphezulu.
-
I-AISI H12 (UNS T20812): Insimbi ye-chromium-molybdenum-tungsten enikeza ukumelana okuhle kakhulu nokukhathala kokushisa kanye nokuqina okuphezulu.
-
I-AISI H13 (UNS T20813): Insimbi ye-chromium-molybdenum-vanadium enokumelana nokuguguleka okuphezulu kanye nokuqina okuhle okubomvu, evame ukubhekwa njengendinganiso yemboni yezikhunta ezisebenzisa i-die-casting.
Lezi zinsimbi zombili zisetshenziswa kabanzi, kodwa izakhi zazo ezithile zokuhlanganisa zakha umehluko ekusebenzeni okwenza zifaneleke kangcono ezinhlotsheni ezahlukene zesikhunta kanye nezimo zokusebenza.
3. Ukuqhathaniswa Kokwakheka Kwamakhemikhali
Umehluko omkhulu phakathi kwe-AISI H12 ne-H13 usekwakhekeni kwazo kwe-alloy, okuthonya ngqo ubulukhuni, ukuqina, kanye nokumelana nokushisa.
