Cov khoom siv dab tsi yog Hastelloy C276?
Hastelloy C276yog ib tug alloy ntawm tooj liab thiab tin, teej tug mus rau ib tug tsawg melting point thiab siab hardness hlau. Nws muaj qhov hnav tsis kam, tiv thaiv corrosion, thiab cuam tshuam tsis kam, tab sis nws yooj yim rau oxidation. Feem ntau yog siv rau hauv kev tsim cov khoom siv xws li cov kabmob, lub zog, lub tes tsho, thiab cov khoom siv kho vajtse xws li li qub.
1. Hastelloy C276 yam ntxwv:
(1) Ceev: 8.90g / cm3.
(2) Melting point: 230 degree C txog 240 degree C. (pib soften thaum cua sov). (Yuav thaum rhuab mus rau 350 degree F ntawm 500 degree F.). (Melting ntawm 600-700 degree F.) Ib qho kev daws ntawm mercury nrog solubility ntawm 0.02% thiab kev daws ntawm 0.2% ammonia lossis ammonium sulfate. (Dissolved nyob rau hauv ammonium hydrobromide tov).
(3) Kub taw tes: 1100 ~ 1130 degree C (decomposition), 1450 ~ 1500 degree C (decomposition); 1600 ~ 1750 ° C (sublimation).
