5.0 hli Ni80Cr20 Bar rau Cov Hlau Sheathed Tubular Elements

Kev Piav Qhia Luv:

NiCr 80 20 yog ib qho hlau nickel-chromium uas siv tau rau qhov kub txog li 1200 ° C. Cov hlau uas tiv taus cua sov siv rau hauv cov huab cua oxidizing xws li nitrogen, ammonia, cov huab cua tsis ruaj khov uas muaj cov sulfur thiab sulfur compounds. NiCr 80/20 muaj cov yam ntxwv tiv taus cua sov siab dua li cov hlau hlau-aluminium.
