4140 vs 42CRMO4 - Ndeupi Musiyano?
AISI 4140 uye 42CrMo4 ndiwo chaiwo mhando yesimbi, ine AISI 4140 iri iyo yekuAmerica zita uye 42CrMo4 iri iyo European zita. Ivo vanogovana akafanana emakemikari ekuumbwa, kusimba kwepamusoro, uye kuomarara, zvichiita kuti ive yakakodzera kukushandisa senge magiya nemabhaudhi. Pasinei nemazita akasiyana uye mazinga ematunhu, anowanzoonekwa seanochinjika nekuda kwezvivakwa zvakafanana.
Chii chinonzi 42CrMo4 simbi?
42CrMo4 isimbi yechromium-molybdenum alloy yakasarudzwa neEuropean standard EN 10083. Inozivikanwa nekusimba kwayo kwepamusoro, kusimba, uye kunaka kuomarara. Iine kabhoni yemukati ye0.38% kusvika 0.45%, inowanzo shandiswa mumashandisirwo anoda zvinhu zvakasimba, senge magiya, crankshafts, uye tsvimbo dzekubatanidza mumaindasitiri akaita semotokari uye aerospace. Simbi inopindura zvakanaka pakurapwa kwekupisa, ichipa kugona kugadzirisa zvinhu zvemuchina, uye inoonekwa seyakaenzana nedzimwe nyika senge AISI 4140 uye SCM440.
Chii chinonzi giredhi B7 simbi?
Giredhi B7 inotsanangurwa mukati meiyo ASTM A193 yakajairwa, iyo inovhara yakakwirira-yakasimba mabhaudhi zvinhu zvekushandisa mukupisa kwepamusoro kana kudzvanya-kumanikidza sevhisi. ASTM A193 chiyero chakagadzirwa neASTM International (yaimbozivikanwa seAmerican Society for Testing and Materials) uye inoshandiswa zvakanyanya mumafuta uye gasi, petrochemical, uye magetsi ekugadzira industries.Grade B7 simbi isimbi yakaderera-alloy chromium-molybdenum simbi inodzimwa uye inodziya (inopisa-inoda kugadzirwa kweGrade 7 yakakosha) kuti iwane iyo simbi inodiwa 'Grade7. inowanzoshandiswa pamwe chete neGiredhi 2H nzungu kuti ive nechokwadi chekuenderana uye kuita mukudiwa kwekunyorera.
