I-ALLOY B-2, UNS N10665
| Ingxubevange B-2 UNS N10665 | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Isifinyezo | I-solid-solution-solution nickel-molybdenum alloy, i-alloy B-2 ikhombisa ukumelana nokugqwala okuhle kakhulu emithonjeni yokunciphisa enolaka efana ne-hydrochloric acid emazingeni okushisa ahlukahlukene nokugxila, kanye ne-sulfuric acid egxilile emaphakathi ngisho ne-chloride elinganiselwe. ukungcola. Ingasetshenziswa futhi kuma-acetic kanye ne-phosphoric acid, kanye nohlu olubanzi lwama-organic acid. Ingxubevange inokumelana okuhle ne-chloride-induced stress corrosion cracking (SCC). | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Okujwayelekile Amafomu Omkhiqizo | Ipayipi, ishubhu, ishidi, ipuleti, ibha eyindilinga, amaflani, ama-valve, nokufoja. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||

| I-Microstructure | Ingxubevange B-2 inobuso-centre-centre-cubic isakhiwo. Ikhemistri elawulwa yingxubevange enokuqukethwe okuphansi kwe-iron ne-chromium kunciphisa ubungozi bokwenzeka kwe-embrittlement ngesikhathi sokwenziwa, njengoba lokhu kuphazamisa ukuna kwesigaba se-Ni4Mo ebangeni lokushisa elingu-700-800 ℃. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Izinhlamvu | 1. Ikhemikhali elawulwayo enokuqukethwe okuphansi kwe-iron ne-chrlmium ukuze kuvinjwe ukwakheka kwe-β-phase Ni4Mo e-odwe; 2. Ukumelana nokugqwala okubalulekile ekunciphiseni imvelo; 3. Ukumelana okuhle kakhulu ne-medium-concentrated sulfuric acid kanye nenani lama-non-oxidizing acid; 4. Ukumelana kahle nokuqhekeka kwe-chloride-induced-corrosion cracking (SCC); 5. Ukumelana kahle nezinhlobonhlobo zama-asidi aphilayo. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Ukumelana Nokugqwala | Okuqukethwe kwekhabhoni ephansi kakhulu ne-silicon ye-Hastelloy B-2 kunciphisa imvula yama-carbides nezinye izigaba endaweni ethinteke ukushisa yama-welds futhi iqinisekisa ukumelana nokugqwala okwanele ngisho nasesimweni esishiselwe. I-Hastelloy B-2 ikhombisa ukumelana nokugqwala okuhle kakhulu emithonjeni yokunciphisa enolaka efana ne-hydrochloric acid ezinhlobonhlobo zamazinga okushisa nokugxila, kanye ne-sulfuric acid egxilile emaphakathi ngisho nokungcoliswa kwe-chloride okulinganiselwe. Ingasetshenziswa futhi kuma-acetic kanye ne-phosphoric acid. I-Optimum corrosion resistance ingatholakala kuphela uma impahla isesimweni esifanele se-metallurgical futhi ibonisa isakhiwo esihlanzekile. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Izinhlelo zokusebenza | Ingxubevange B-2 isetshenziswa ezinhlobonhlobo zezicelo embonini yezinqubo zamakhemikhali, ikakhulukazi ezinqubweni ezibandakanya i-sulphuric, i-hydrochloric, i-phosphoric ne-acetic acid. I-B-2 ayinconywa ukuthi isetshenziswe lapho kukhona usawoti we-ferric noma we-cupric njengoba lawa sawoti angase abangele ukwehluleka ukugqwala okusheshayo. Usawoti we-ferric noma we-cupric ungakhula lapho i-hydrochloric acid ihlangana nensimbi noma ithusi. |
