4140 vs 42CRMO4 – Uyini Umehluko?
I-AISI 4140 kanye ne-42CrMo4 empeleni ziwuhlobo olufanayo lwensimbi, kanti i-AISI 4140 iyigama laseMelika kanye ne-42CrMo4 iyigama laseYurophu. Zinezakhi zamakhemikhali ezifanayo, amandla aphezulu, nokuqina, okwenza zifaneleke ukusetshenziswa njengegiya namabholidi. Naphezu kwezimpawu ezahlukene kanye nezindinganiso zesifunda, zivame ukubhekwa njengezingashintshaniswa ngenxa yezakhiwo ezifanayo.
Iyini insimbi engu-42CrMo4?
I-42CrMo4 iyinsimbi ye-chromium-molybdenum alloy eqokwe yi-European standard EN 10083. Yaziwa ngamandla ayo aphezulu, ukuqina, kanye nokuqina okuhle. Njengoba inokuqukethwe kwekhabhoni okungu-0.38% kuya ku-0.45%, ivame ukusetshenziswa ezinhlelweni zokusebenza ezidinga izingxenye eziqinile, njengegiya, ama-crankshaft, kanye nezinduku zokuxhuma ezimbonini ezifana nezimoto kanye nezindiza. Insimbi isabela kahle ekwelashweni kokushisa, inikeza ikhono lokulungisa izakhiwo zemishini, futhi ibhekwa njengelingana nomhlaba wonke nezinye izikhundla ezifana ne-AISI 4140 kanye ne-SCM440.
Iyini insimbi yebanga le-B7?
Ibanga B7 liyincazelo engaphakathi kwendinganiso ye-ASTM A193, ehlanganisa izinto zokubopha ezinamandla aphezulu ezisetshenziswa ezinsizakalweni zokushisa okuphezulu noma zokucindezela okuphezulu. I-ASTM A193 iyindinganiso ethuthukiswe yi-ASTM International (eyayaziwa ngokuthi i-American Society for Testing and Materials) futhi isetshenziswa kabanzi embonini kawoyela negesi, i-petrochemical, kanye neyokukhiqiza ugesi. Insimbi yebanga B7 iyinsimbi ye-chromium-molybdenum ene-alloy ephansi ecinywayo futhi ishisiswe (iphathwe ngokushisa) ukuze kufezwe izakhiwo zemishini ezifiselekayo. Kubalulekile ukuqaphela ukuthi insimbi yebanga B7 ivame ukusetshenziswa ngokuhlanganiswa nama-nuts ebanga 2H ukuqinisekisa ukuhambisana nokusebenza ezinhlelweni ezidinga amandla. Uma kuchazwe, izinto kumele zihlangabezane nezidingo ezichazwe ezindinganisweni ze-ASTM A193 kanye ne-A194 ukuqinisekisa amandla afanele, ukuguquguquka, kanye nezinye izakhiwo zemishini.
