45 # inopisa yakakungurutswa simbi pepa

Iyo yakakurudzirwa kupisa kupisa system ye45 simbi inotsanangurwa muGB/T699-1999 standard iri normalizing pa850 ° C, inodzima pa840 ° C, uye kupisa pa600 ° C. Kuitwa kwaitwa igoho simba ≥355MPa
Iyo GB/T699-1999 yakajairwa inotaura kuti kusimba kwesimbi makumi mana neshanu i600MPa, simba regoho i355MPa, chiyero chekureba i16%, uye kudzikiswa kwenzvimbo i40%.
Application
Kwete 45 simbi inoshandiswa zvakanyanya mumashini, kana isiri kupisa kupisa: HB≤229; kupisa kurapwa: normalizing; simba rekuita: Aku≥39J; simba rakakwirira, plastiki yakanaka uye kuoma, 45# ndiro yesimbi mushure mekudzima pasina kupisa, kuoma kwakakura kudarika HRC55 (Kusvika kuHRC62) inokodzera. Mushure mekupisa kupisa uye kupisa, inogona kusvika kuHRC42-46, iyo isingagone kungoita yakanaka ma mechanic properties, asiwo kuwana kuomarara zvinodiwa pamusoro. Inoshandiswa kuita zvigadziriso zviduku zvechikamu zvinogona kumira mitoro yakakura. Zvikamu zvemhando yepamusoro uye zvikamu zvakakura zvakajairwa zvine kushushikana kushoma, pamwe nenzvimbo dzakaomeswa dzepamusoro dzisingade simba repakati, senge matipi, madhijitari, maoko ekutarisa uye zvimwe zvikamu.
