Cr20ni80 NiCr8020 Nicr Alloy Nichrome Hlau rau Cov Khoom Siv Cua Sov

Kev Piav Qhia Luv:

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 hauv tsev rauv taws thiab cov cua sov conductors. Nws yog ib qho 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 hloov pauv ntau zaus lossis kev hloov pauv kub dav dav. Kev tiv thaiv rau atmospheric corrosion ntawm 20 ° C yog siab txog rau qhov kub ua haujlwm siab dua 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 kev txo cov pa uas muaj sulfur. Kev tiv thaiv rau carbonizing yog siab. Daim ntawv thov rau cov chaw ua hluav taws xob hauv kev lag luam, cov chaw ua kom sov enamelling, cov khoom siv hauv tsev, cov chaw khaws cia hmo ntuj tam sim no.
