Maishiy texnikada ishlatiladigan Ni80Cr20 Ni70Cr30 Ni60Cr15 Ni35Cr20 ning zavod nikrom qotishma chizig'i
Zavodning Nikrom qotishma chizig'iNi80Cr20Ni70Cr30 Ni60Cr15 Ni35Cr20 maishiy texnikada ishlatiladi
Ni70Cr30 ostenitik nikel-xrom qotishmasi bo'lib, 1250 ° S gacha bo'lgan haroratni qo'llash uchun mos keladi. Yuqori xrom miqdori (o'rtacha 30%), ayniqsa o'choq ilovalarida juda yaxshi ishlash muddatini ta'minlaydi. Ni70Cr30 yuqori qarshilik, yaxshi oksidlanishga chidamlilik, foydalanishdan keyin yaxshi egiluvchanlik va mukammal payvandlash qobiliyati bilan ajralib turadi.
Ni70Cr30 sanoat pechlarida elektr isitish elementlari uchun ishlatiladi. Odatda qo'llanilishi: elektr va emalli pechlar, saqlash isitgichlari, pechlar va o'zgaruvchan atmosferaga ega pechlar.
