Product FEATURE
1. B-3 alloy yog ib tus tswv cuab tshiab ntawm cov nickel alloy tsev neeg, nws muaj kev tiv thaiv zoo heev rau hydrochloric acid ntawm txhua qhov kub thiab txias, thiab zoo corrosion kuj rau sulfuric acid, acetic acid, formic acid, phosphoric acid, thiab lwm yam uas tsis yog-oxidizing media.
2. Vim yog kev hloov kho ntawm nws cov tshuaj muaj pes tsawg leeg, nws cov thermal stability tau zoo dua qub piv nrog cov qub B-2 alloy. B-3 alloy muaj kev ua haujlwm siab rau pitting corrosion, kev nyuaj siab corrosion, cutter corrosion thiab corrosion nyob rau hauv tshav kub cuam tshuam cheeb tsam ntawm vuam.
daim ntawv thov
B-3 alloy tuaj yeem siv rau hauv txhua daim ntawv thov ntawm B-2 alloy yav dhau los. Zoo li B-2 alloy, B-3 tsis pom zoo rau siv nyob rau hauv ib puag ncig uas trivalent hlau thiab divalent tooj liab ntsev yog tam sim no, vim tias cov ntsev no tuaj yeem ua rau corrosion sai. Thaum hydrochloric acid los rau hauv kev sib cuag nrog hlau thiab tooj liab, nws chemically reacts nrog lawv los tsim trivalent hlau thiab divalent tooj liab ntsev.
