420J1 420J2 simbi isina tsvina
Tsanangudzo Pfupi:
420J1 uye 420J2 Stainless simbi mitsetse mhando mbiri dzakajairika dzesimbi isina simbi inova yemartensitic Stainless steel series. Vane mimwe misiyano mukugadzirwa kwemakemikari uye maitiro. Heino mhedziso pfupi yeumwe neumwe:
1. 420J1 Stainless steel strip: 420J1 isimbi yakaderera-kabhoni isina tsvina ine kuoma kwakanyanya uye simba. Makemikari ayo anowanzo sanganisira yakatenderedza 0.16-0.25% kabhoni, ingangoita 1% chromium, uye mashoma emolybdenum. 420J1 inopa yakanaka corrosion kuramba, kucheka kuita, uye kukuya zvivakwa. Inowanzo shandiswa kugadzira mapanga, zviridzwa zvekuvhiya, mativi emuchina, uye mamwe maapplication anoramba kupfeka.
2. 420J2 Stainless steel strip: 420J2 isimbi yepakati-kabhoni isina tsvina ine kuoma kwepamusoro uye kusakara kwekupfeka. Kuumbwa kwayo kwemakemikari kunowanzo kuve kwakatenderedza 0.26-0.35% kabhoni uye inenge 1% chromium. 420J2 ine yakakwira kabhoni yemukati ichienzaniswa ne420J1, zvichikonzera kuwedzera kuoma uye kucheka kuita. Inowanzo shandiswa kugadzira mapanga, mapanga, zviridzwa zvekuvhiya, zvitubu, uye zvimwe zvikamu zvemakanika.
