Hastelloy B: Say Corrosion-Resistant Vanguard ed Reductive Corrosive Environments

Bilang nickel-molybdenum-based corrosion-alloy, say Hastelloy B et nagmaliw ya manunan materyal ed saray industriya a singa say chemical engineering tan petrolyo parad pangasikaso ed saray kaliberliber ya makaderal, lapud nikadkaduman performance to ed reductive acid media. Saray bentaha to et lalon mabitabitar no ikompara ed saray mipadparan alloy.

Diad reductive acid ya kaliberliber a singa say hydrochloric acid tan dilute sulphuric acid, say resistensya na Hastelloy B ed corrosion et singa "benchmark." Aliwan singa say 316L stainless steel, ya maples ya onkakapuy ed medium-concentration hydrochloric acid, say Hastelloy B et makapankimey ya malet ed hydrochloric acid diad temperaturan abeba nen 80 degree. No ikompara ed nickel-chromium alloys (alimbawa, Inconel 600) ya akasentro ed resistensya ed oxidation, say atagey ya molybdenum content to (26%-30%) et manporma na malet ya passive layer, ya epektibon onresisti ed hydrogen ion erosion tan mangaasikaso ed isyu na passive film degradation ed saray reductive acids ya aarapen na saray unor.

Say Hastelloy B et maong met ed saray reductive ya kaliberliber ya walay atagey ya konsentrasyon na chloride ion. Ag-itan ontutumbok, ag-onkupas so abot, tan ag-onkupas so stress. No ikompara ed saray titanium alloys, ya mainomay ya naderal so hydrogen ed reductive hydrochloric acid, odino saray Monel alloys, ya anggapoy magenap ya resistensya ed corrosion ed atagey-temperatura, atagey-concentration hydrochloric acid, say Hastelloy B et mangiyoopresi na mas maabig ya andukey a panaon ya estabilidad. Anggan diad atagey a temperatura (200-300℃) reductive acids odino sulfur-ya walaan na media-singa say mairap iran kondisyon na petroleum hydrodesulfurization units-mansiasiansia itan na ekselentin mekanikal iran kablian tan resistensya ed corrosion, ya onlampas ed ordinaryon {12} asero tan pigaran nikel-chromium-iron alloys.

Say nikadkaduman bentaha to ed arum ya grado na Hastelloy et naimano: diad puron reductive hydrochloric acid, mas maong so resistensya to ed corrosion nen say Hastelloy C series (ya mas maong ed mixed media) diad mas abeban presyo; diad atagey a konsentrasyon na hydrochloric acid, say resistensya to ed corrosion et onlampas ed Hastelloy G series, ya akasentro ed resistensya na sulfuric acid.

Manlapud saray laboratoryo anggad saray industriyal a pasen, say Hastelloy B, a walaan na saray bentaha ton ag-onkukurang ed panag-apag, so ompapaway bilang sakey a nakaukolan a "protective barrier" ed saray kaliberliber ya ag-onkupas.
