Ngokwezifiso i-Chrome Molybdenum 42CrMo4 ingxubevange yensimbiimikhiqizo yokutshala imalifor lock hook of imoto ngeukwelashwa kwe-electrophoresis surface.
I-42CrMo4 (1.7225) evela ekucacisweni kwe-EN 10083-3, evamise ukuphathwa ngokushisisa yi-QT (Queching + Tempering), isetshenziswa kakhulu ukukhiqiza ukukhishwa kokutshalwa kwezimali. Unamandla amakhulu, ukuqina okuphezulu, ukuqina okuhle, ukufutheka kwentukuthelo, umkhawulo wokukhathala, ukumelana nomthelela omuhle ngemva kokucisha nokushisa, kanye nokuqina okuhle komthelela ophansi wokushisa. Ibanga elilinganayo le-42CrMo4 lithi 4140 (ASTM, USA) kanye ne-42CrMo (GB/T 3077, China)

CInsimbi ye-arbon, insimbi ephansi ye-alloy, insimbi ephezulu ye-alloy kanye nezinsimbi zensimbi zisetshenziswa ezinhlelweni eziningi zezimboni. Ngamamaki akho amaningi, insimbi nama-alloys azo kungelashwa ukuze kuthuthukiswe isivuno sawo namandla aqinile futhi, kulungiswe ubulukhuni noma ukuguquguquka kwezidingo zohlelo lukanjiniyela noma izici zomshini ezifiswayo.

Ukusebenzisa i-inqubo yokutshala imali, Isikhungo sokusakaza se-RMC siyakwazi ukuhlangabezana nezimfuneko zempahla ngokuvumelana nezindinganiso ze-ASTM, SAE, AISI, ACI, DIN, EN, ISO, kanye ne-GB. Sinama-alloys angaphezu kwe-100 ahlukene ayinsimbi futhi angeyona ayoni esiphonsa ngawo izingxenye sisebenzisa indlela yokuklama eyinkimbinkimbi. Ukusakazwa kwethu kokutshalwa kwezimali okunobukhulu kanye nejiyomethrikhi okuyinkimbinkimbi kukhiqizwa ngendlela efanele, kunciphisa isidingo somshini wesibili.
Insimbi eyi-Chromium-molybdenum cast isetshenziswa kakhulu emikhakheni yezimboni enezakhiwo ezisezingeni eliphakeme uma kuqhathaniswa. Ukwengezwa kwe-molybdenum kunsimbi ye-chromium kungakhuphula amandla okubunjwa kwensimbi ngaphandle kokuba nomthelela obalulekile ekuqineni komthelela kwensimbi ekhonjiwe. Ngaphezu kwalokho, insimbi ye-chromium-molybdenum cast inokusebenza okuhle kakhulu kokushisa okuphezulu nokumelana nokukhuphuka. Ngemuva kokucisha nokushisa noma ukujwayela ukwelashwa kokushisa, insimbi ye-chromium-molybdenum cast ingathola izakhiwo ezinhle kakhulu zokusebenzisa.
I-Molybdenum ingathuthukisa ukuqina kwensimbi ekhonjiwe futhi inciphise ukufutheka kwensimbi. Insimbi eyinsimbi ye-Chromium-molybdenum isetshenziselwa ukulingisa kwesigaba esikhulu nokulingisa kwensimbi okudinga ukuqina okujulile.
