Inyungu za AR Steel?
Jindalai Steel itanga icyuma cya AR mubyuma binini kandi bito kubashushanya n'abashinzwe inganda bashaka kongera igihe cya serivisi y'ibice bikomeye no kugabanya uburemere bwa buri gice cyashyizwe muri serivisi. Inyungu zo gukoresha isahani idashobora kwangirika mubisabwa birimo ingaruka na / cyangwa kunyerera hamwe nibikoresho byangiza ni byinshi.
Isahani irwanya ibyuma biraramba cyane kandi birinda kwambara, birinda neza ibisebe. Ubu bwoko bwibyuma bukora neza mubikorwa bikarishye, kandi butanga ningaruka zo kurwanya. Kwambara isahani idashobora kwihanganira amaherezo bizagufasha kongera igihe cyo gusaba kwawe no kugabanya ibiciro byawe mugihe kirekire.

| Ibindi | Ibintu byongeweho Alloying birashobora kongerwaho kugirango byongere imitekerereze irwanya abrasion. | Ibintu byongeweho Alloying birashobora kongerwaho kugirango byongere imitekerereze irwanya abrasion. | Ibintu byongeweho Alloying birashobora kongerwaho kugirango byongere imitekerereze irwanya abrasion. |
| Ingano | 3/16 ″ - 3 ″ (Ubugari 72 ″ - 96 ″ - 120 ″) | 3/16 ″ - 3 ″ (Ubugari 72 ″ - 96 ″ - 120 ″) | 1/4 ″ - 2 1/2 ″ (Ubugari 72 ″ na 96 ″) |
Ibyiza bya AR400 NA AR500 Ibyapa
AR400 ni "gukomera-gukomera", irwanya abrasion, isahani yambara. Urwego rukomeye ni 360/440 BHN hamwe nizina rya 400 BHN. Ubushyuhe bwa serivisi ni 400 ° F. Ibicuruzwa byisahani bigenewe gukoreshwa mubisabwa aho hasabwa uburinganire bwiza bwo guhinduka, gusudira, gukomera no kurwanya abrasion. Ibyuma birwanya abrasion mubisanzwe bigurishwa kurwego rukomeye ntabwo ari chimie ihamye. Guhinduranya gato muri chimie birahari bitewe nurusyo rutanga. Ibisabwa birashobora kubamo gukoresha ubucukuzi bw'amabuye y'agaciro, kariyeri, gutunganya ibikoresho byinshi, uruganda rukora ibyuma, n'inganda zimpapuro. Kwambara ibicuruzwa byateguwe kubikoresho bya liner; ntibagenewe gukoreshwa nkibikoresho byunganira cyangwa ibikoresho byo guterura.
AR500 ni "igikomangoma", irwanya abrasion, isahani yambara. Urwego rukomeye ni 470/540 BHN hamwe nizina rya 500 BHN. Ibicuruzwa byisahani bigenewe gukoreshwa mubisabwa aho hasabwa impirimbanyi nziza zingaruka, gukomera no kurwanya abrasion. Ibyuma birwanya abrasion mubisanzwe bigurishwa kurwego rukomeye ntabwo ari chimie ihamye. Guhinduranya gato muri chimie birahari bitewe nurusyo rutanga. Ibisabwa birashobora gukoreshwa harimo gucukura amabuye y'agaciro, kariyeri, gutunganya ibintu byinshi, gusya ibyuma, n'inganda zimpapuro. Kwambara ibicuruzwa byateguwe kubikoresho bya liner; ntibagenewe gukoreshwa nkibikoresho byunganira cyangwa ibikoresho byo guterura.
AR400 VS AR450 VS AR500 + Ibyapa
Urusyo rutandukanye rushobora kugira "resept" zitandukanye zicyuma cya AR, ariko ibikoresho byakozwe bitangwa ikizamini gikomeye - kizwi nka Brinell Test - kugirango umenye icyiciro kigwamo. Ibizamini bya Brinell bikozwe mubikoresho bya AR mubisanzwe byujuje ASTM E10 kugirango igerageze gukomera.
Itandukaniro rya tekiniki hagati ya AR400, AR450 na AR500 numubare wa Brinell (BHN), byerekana urwego rwibintu bikomeye.
AR400: 360-440 BHN Mubisanzwe
AR450: 430-480 BHN Mubisanzwe
AR500: 460-544 BHN Mubisanzwe
AR600: 570-625 BHN Mubisanzwe (ntibisanzwe, ariko birahari)
