Cov Cim Npe Khoom

Cov khoom siv NiCr8020 nrog cov khoom siv tus lej 2.4869 yog siv rau hauv daim ntawv ntawm cov strips, sheets, raj thiab xov hlau rau cov khoom siv tsim kho lub cub tawg thiab cov cua sov conductors.

Nws yog ib qho hlau nickel-chromium cua sov conductor alloy rau kev ua haujlwm kub txog li 1150 ° C thiab feem ntau muaj cov khoom ntxiv ntawm cov av tsis tshua muaj rau kev tiv thaiv oxidation ntau dua, tshwj xeeb tshaj yog nrog kev ua haujlwm hloov pauv ntau zaus lossis kev hloov pauv kub dav.

Qhov kev tiv thaiv rau qhov xeb hauv huab cua ntawm 20 ° C yog siab txog rau qhov kub ua haujlwm siab qhov kev tiv thaiv rau huab cua thiab lwm yam pa oxygen nrog rau cov pa nitrogen-muaj pa oxygen tsawg kuj siab, tsis tau nws qis rau oxidizing nrog rau txo cov pa sulfur.

Qhov kev tiv thaiv rau carbonizing yog siab. Daim ntawv thov rau cov cub hluav taws xob hauv kev lag luam, cov cub tawg enamelling, cov khoom siv hauv tsev, cov cua sov cia khoom hmo ntuj.
