Warshada Nichrome Alloy Strip of Ni80Cr20 Ni70Cr30 Ni60Cr15 Ni35Cr20 Loo Isticmaalay Qalabka Guriga
Factory Nichrome Alloy Strip ofNi80Cr20Ni70Cr30 Ni60Cr15 Ni35Cr20 Loo Isticmaalay Qalabka Guriga
Ni70Cr30 waa austenitic nikkel-chromium alloy ku habboon codsiyada heerkulka ilaa 1250 ° C. Maadada chromium sare (30% celcelis ahaan) waxay bixisaa waqti nololeed oo aad u wanaagsan, gaar ahaan codsiyada foornada. Ni70Cr30 waxaa lagu gartaa iska caabin sare, iska caabin oksaydh wanaagsan, ductility wanaagsan ka dib isticmaalka iyo alxanka heer sare ah.
Ni70Cr30 waxaa loo isticmaalaa walxaha kululaynta korontada ee foornooyinka warshadaha. Codsiyada caadiga ah waa: foornooyinka korantada iyo dhaldhalaalka, kuleyliyeyaasha kaydinta, foornooyinka iyo kilnnada jawiga isbeddelaya.
Guryaha Makaanikada ee caadiga ah (1.0mm)
- Kordhinta: 30%
- Awoodda Wax-soo-saarka: 420Mpa
- Awoodda Xakamaynta: 810Mpa
