SAE8620H Steel Round Bar /GB 20CrNiMo Steel bar
Features
8620 alloy simbi inoumbwa ne (mukudzika kurongeka kwezana) iron, kabhoni, silicon, molybdenum, manganese, nickel, chromium, sulfur uye phosphorus.Izvi zvinongedzo zvinofanirwa kunge zviri mukati memamwe uremu muzana kugadzira iyo 8620 alloy.Inokurudzirwa kuti simbi iomerwe ne carburization inoteverwa nemafuta, kusiyana nemvura, kudzima.Iine mwero wakakwana weavhareji yealloys yesimbi pa.28 lb. per square inch, kunyange zvazvo simba rayo rekusimba - huwandu hwehuremu hwainokwanisa kubata isati yatyoka - yakaderera, pa536.4 Mpa.Avhareji yekusimba kwesimbi alloys ndeye 758 kusvika 1882 Mpa.
Kana iyo 8620 alloy yakanyatsogadziriswa carburized - inopisa kusvika kune yakagadzika tembiricha yobva yaiswa kune agent ine kabhoni, maitiro anowedzera imwe yakawedzera kabhoni kunze kwesimbi, nekudaro ichiisimbisa - inoshandiswa kugadzira muchina wakadaro. zvikamu semagiya, crankshafts, uye mhete dzegiya.Carburized 8620 alloy yakasimba uye inogara, ndosaka inosarudzwa kune izvi zvikamu.

SAE8620H Steel Bar Application
Inowanzo shandiswa kugadzira zvikamu zvakakosha zvine simba rakakura uye yakanaka plastiki, uye yekugadzira zvikamu zvakakosha zvine zvakakosha zvinoshanda zvinodiwa mushure mekurapa nitriding:
Heavy-duty arbors, bushings, Cam Followers, kupfeka mapini, mabearings, sprockets, gears and shafts, Clutch Dogs, Compressor Bolts, Extractors, Fan Shafts, Heavy Duty Gears, Pump Shafts, Sprockets, Tappets, Wear Pins, Wire Guides etc. Kana kuti inogona kushandiswa kune yakakwira tensile application uncarburised asi kuburikidza nekuomeswa nekudzikamiswa.Inoshandiswa zvakanyanya nese indasitiri zvikamu zvezvikamu uye shafts inoda yakakwira yekupfeka kupfeka kuramba, yakakwira musimboti simba uye maitiro ekuita.
Package
