420J1 420J2 simbi isina ngura
Tsananguro pfupi:
Mitsetse yesimbi isina ngura ye420J1 ne420J2 mhando mbiri dzakajairika dzezvinhu zvesimbi isina ngura zviri mumhando yesimbi isina ngura yemartensitic. Dzine musiyano mukugadzirwa kwemakemikari uye hunhu. Heino pfupiso yechimwe nechimwe:
1. 420J1 simbi isina ngura: 420J1 isimbi isina ngura ine kabhoni shoma ine kuomarara kwakanyanya uye simba rayo. Makemikoro ayo anowanzo sanganisira kabhoni inosvika 0.16-0.25%, inenge 1% chromium, uye molybdenum diki. 420J1 inopa simba rakanaka rekudzivirira ngura, kugona kucheka, uye kugona kukuya. Inowanzoshandiswa kugadzira mapanga, zvishandiso zvekuvhiya, zvikamu zvemakanika, uye zvimwe zvinoshandiswa zvisingapfeki.
2. 420J2 simbi isina ngura: 420J2 isimbi isina ngura ine kabhoni iri pakati nepakati ine kuomarara kwakanyanya uye inodzivirira kupera. Makemikoro ayo anowanzo kuve nekabhoni inosvika 0.26-0.35% uye inenge 1% chromium. 420J2 ine kabhoni yakawanda zvichienzaniswa ne420J1, zvichikonzera kuomarara kwakanyanya uye kushanda zvakanaka kwekucheka. Inowanzoshandiswa kugadzira mapanga, mapanga, zvishandiso zvekuvhiya, masipiringi, nezvimwe zvikamu zvemakanika.
