4140 vs 42CRMO4 – Uyini Umehluko?
I-AISI 4140 kanye ne-42CrMo4 empeleni ziwuhlobo olufanayo lwensimbi, ne-AISI 4140 okuyigama laseMelika kanye ne-42CrMo4 okuyigama laseYurophu. Babelana ngokuqanjwa kwamakhemikhali okufanayo, amandla aphezulu, nokuqina, okubenza bafanelekele izinhlelo zokusebenza ezifana namagiya namabhawudi. Naphezu kokuqokwa okuhlukile namazinga esifunda, ngokuvamile abhekwa njengokushintshana ngenxa yezakhiwo ezifanayo.
Iyini insimbi ye-42CrMo4?
I-42CrMo4 iyinsimbi ye-chromium-molybdenum alloy ekhethwe ngezinga le-European standard EN 10083. Yaziwa ngamandla ayo aphezulu, ukuqina, nokuba lukhuni kahle. Ngokuqukethwe kwekhabhoni okungu-0.38% kuya ku-0.45%, ivamise ukusetshenziswa ezinhlelweni ezidinga izingxenye eziqinile, njengamagiya, ama-crankshafts, nezinduku zokuxhuma ezimbonini ezifana nezezimoto kanye ne-aerospace. Insimbi isabela kahle ekwelapheni ukushisa, ihlinzeka ikhono lokulungisa izakhiwo zemishini, futhi ibhekwa njengelingana namazwe ngamazwe kwezinye izibizo ezifana ne-AISI 4140 ne-SCM440.
Iyini i-grade B7 steel?
IBanga B7 liwukucaciswa okungaphakathi kwezinga le-ASTM A193, elimboza izinto zokubhowula eziqine kakhulu ezizosetshenziswa emazingeni okushisa aphezulu noma anengcindezi ephezulu. I-ASTM A193 iyindinganiso eyathuthukiswa yi-ASTM International (ngaphambili eyayaziwa ngokuthi i-American Society for Testing and Materials) futhi isetshenziswa kakhulu ezimbonini zikawoyela negesi, i-petrochemical, neziphehla amandla.Insimbi yeBanga B7 iyinsimbi enealloy ephansi ecishwayo futhi efudumalayo (ephathwe ngokushisa) ukuze kuzuzwe izakhiwo ezifiselekayo zemishini.Kubalulekile ukuqaphela ukuthi insimbi yeBanga B7 ivame ukusetshenziswa ngokuhambisana namantongomane eBanga 2H ukuze kuqinisekiswe ukuhambisana nokusebenza ezicelweni ezifunayo. Uma kucacisiwe, izinto ezisetshenziswayo kufanele zihlangabezane nezidingo ezichazwe kumazinga we-ASTM A193 kanye ne-A194 ukuze kuqinisekiswe amandla afanele, i-ductility, nezinye izakhiwo zemishini.
