Hastelloy B-2 / B-3 iṣelọpọ
Awọn orukọ Iṣowo ti o wọpọ: Hastelloy B-2,NS3202,UNS N10665,NiMo28, W.Nr.2.467,NiMo28
Hastelloy B2 jẹ ojutu ti o lagbara ti o lagbara, alloy nickel-molybdenum, pẹlu atako pataki si idinku awọn agbegbe bii gaasi kiloraidi hydrogen, ati sulfuric, acetic ati awọn acids phosphoric.Molybdenum jẹ eroja alloying akọkọ eyiti o pese idiwọ ipata pataki si idinku awọn agbegbe.Eleyi nickel irin alloy le ṣee lo ni bi-welded majemu nitori ti o koju awọn Ibiyi ti ọkà-aala carbide precipitates ni weld ooru-fowo agbegbe.Nickel alloy yii n pese resistance to dara julọ si hydrochloric acid ni gbogbo awọn ifọkansi ati awọn iwọn otutu.Ni awọn afikun, Hastelloy B2 ni o ni o tayọ resistance to pitting, wahala ipata wo inu ati si ọbẹ-ila ati ooru-ipa agbegbe kolu.Alloy B2 n pese resistance si imi-ọjọ imi-ọjọ ati nọmba awọn acids ti kii ṣe oxidizing.

Kí nìdí Hastelloy B-2?
Alloy B-2 ni ko dara ipata resistance si oxidizing awọn agbegbe, nitorina, o ti wa ni ko niyanju fun lilo ninu oxidizing media tabi niwaju ferric tabi cupric iyọ nitori won le fa dekun ipata ikuna.Awọn iyọ wọnyi le dagbasoke nigbati hydrochloric acid ba wa ni ifọwọkan pẹlu irin ati bàbà.Nitoribẹẹ, ti a ba lo alloy yii ni apapo pẹlu irin tabi fifin bàbà ninu eto ti o ni hydrochloric acid ninu, wiwa awọn iyọ wọnyi le fa alloy lati kuna laipẹ.Ni afikun, irin alloy nickel yii ko yẹ ki o lo ni awọn iwọn otutu laarin 1000 ° F ati 1600 ° F nitori idinku ninu ductility ninu alloy.
•O tayọ ipata resistance fun ayika reductive.
•O tayọ resistance si imi-ọjọ acid (ayafi fun ogidi) ati awọn miiran ti kii-oxidizing acids.
•Atako ti o dara si didan ipata wahala (SCC) ti o ṣẹlẹ nipasẹ awọn chlorides.
•O tayọ resistance to ipata ṣẹlẹ nipasẹ Organic acids.
•Idaabobo ipata ti o dara paapaa fun agbegbe igbona alurinmorin ni ipa agbegbe nitori ifọkansi kekere ti erogba ati ohun alumọni.
Aaye ohun elo Hastelloy B-2:
Ti a lo jakejado ni kemikali, petrochemical, iṣelọpọ agbara ati iṣakoso idoti ti o ni ibatan ati ohun elo,
Ni pataki ninu awọn ilana ti o nlo pẹlu ọpọlọpọ awọn acids (sulfuric acid, hydrochloric acid, phosphoric acid, acetic acid).
