40cr halaye 40cr babban manufa 40cr yadda ake zafi magani

1. Gabatarwa zuwa 40cr: 40Cr karfe ne matsakaici-carbon modulated karfe. Normalizing iya inganta spheroidization na tsarin da kuma inganta wasan kwaikwayo na blank tare da taurin ƙasa da 160HBS. Tempering a zazzabi na 550 ~ 570 ℃, da karfe yana da mafi kyau m inji Properties. Hardenability na wannan karfe ya fi na karfe 45, kuma ya dace da jiyya mai taurin ƙasa kamar yawan kashe wuta da kuma kashe wuta.

Na biyu, 40cr halaye: matsakaici carbon quenched da tempered karfe, sanyi heading mutu karfe. Ƙarfe yana da matsakaicin farashi kuma mai sauƙin sarrafawa. Bayan maganin zafi mai kyau, ana iya samun wani nau’i na tauri, filastik da juriya. Sashin daidaitawa yana haɓaka spheroidization na tsarin kuma ya dace da jiyya taurin saman ƙasa kamar kashe mitoci mai ƙarfi da kashe wuta.

Na uku, babban manufar 40cr: rabin shaft da gears, shafts, tsutsotsi, spline shafts, saman hannayen riga a kan kayan aikin inji, da dai sauransu; bayan quenching da tempering a matsakaici zafin jiki, ana amfani da su kerarre sassa da cewa jure babban nauyi, tasiri da kuma matsakaici gudun aiki, kamar gears, Sleeve, shaft, babban shaft, crankshaft, 182 spindle, 3666 fil, 3769 haɗa sanda, dunƙule, goro, bawul ɗin ci, da dai sauransu Bugu da ƙari, irin wannan ƙarfe ya dace da kera sassa daban-daban na watsawa waɗanda ke yin maganin carbonitriding, irin su gears da shafts tare da diamita mafi girma da kuma ƙarancin zafin jiki mai kyau.

Hudu, 40cr sinadaran abun ciki:

Carbon 0.37 ~ 0.45%, silicon 0.17 ~ 0.37%, manganese 0.5 ~ 0.8, chromium 0.8 ~ 1.1%

Ƙunƙarar baƙin ciki: ƙasa da 207HBS

Taurin daidaitawa: ƙasa da 250HBS

Biyar, Matsayin bayarwa na 40cr: Matsayin bayarwa na 40Cr ana isar da shi ta hanyar magani mai zafi (na al’ada, annealing ko zafin zafin jiki) ko ba tare da magani mai zafi ba. Ya kamata a nuna matsayin bayarwa a cikin kwangilar.

Shida, 40cr zafi magani: quenching a 850 ℃, mai sanyaya; tempering a 520 ℃, ruwa sanyaya, mai sanyaya. Ƙaƙƙarfan taurin 40Cr shine HRC52-60, kuma quenching harshen wuta na iya kaiwa HRC48-55.
