Hastelloy B
Hastelloy B yog ib qho kev daws teeb meem ntxiv dag zog, npib tsib xee-molybdenum alloy, nrog kev tiv thaiv tseem ceeb los txo qhov chaw xws li hydrogen chloride gas, thiab sulfuric, acetic thiab phosphoric acids. Molybdenum yog lub ntsiab alloying uas muab kev tiv thaiv corrosion tseem ceeb los txo qhov chaw. Cov nickel steel alloy no tuaj yeem siv tau rau hauv qhov chaw zoo li-welded vim tias nws tiv thaiv kev tsim ntawm cov qoob loo ntawm cov ciam teb carbide precipitates nyob rau hauv qhov chaw weld tshav kub.
Cov nickel alloy no muab kev tiv thaiv zoo rau hydrochloric acid ntawm txhua qhov ntau thiab kub. Tsis tas li ntawd, Hastelloy B2 muaj kev tiv thaiv zoo heev rau pitting, kev nyuaj siab corrosion cracking thiab rau riam-kab thiab tshav kub-tshem tawm tsam. Alloy B muab kev tiv thaiv rau cov ntshiab sulfuric acid thiab ib tug xov tooj ntawm non-oxidizing acids.

HASTELLOY B2 UNS N10665 W.NR.2.4617
Hastelloy B2 yog ib qho kev daws teeb meem ntxiv dag zog, npib tsib xee-molybdenum alloy, nrog kev tiv thaiv tseem ceeb los txo qhov chaw xws li hydrogen chloride gas, thiab sulfuric, acetic thiab phosphoric acids. Molybdenum yog qhov tseem ceeb ntawm cov khoom siv alloying uas muab kev tiv thaiv corrosion tseem ceeb rau kev txo qis ib puag ncig. Cov nickel steel alloy no tuaj yeem siv tau rau hauv qhov chaw zoo li-welded vim tias nws tiv thaiv kev tsim ntawm cov qoob loo ntawm cov ciam teb carbide precipitates nyob rau hauv qhov chaw weld tshav kub.

Hastelloy C-276 Cov Ntaub Ntawv Cov Ntaub Ntawv
HASTELLOY C276, UNS N10276 yog suav tias yog ntau yam corrosion resistant npib tsib xee alloy muaj. Alloy C-276 kuj muaj kev tiv thaiv zoo heev rau pitting, kev nyuaj siab-corrosion cracking, tshwj xeeb tshaj yog tsim rau siv nyob rau hauv high kub, inorganic thiab organic acids tov nrog impurities (xws li formic acid thiab acetic acid), thiab seawater corrosive ib puag ncig.

Alloy 2205 Duplex Stainless Phaj
Lub tuam txhab Sandmeyer Steel muaj cov khoom muag dav dav ntawm 2205 duplex stainless hlau phaj hauv thicknesses los ntawm 3/16 "(4.8mm) txog 6" (152.4mm). Lub zog tawm los yog kwv yees li ob zaug ntawm austenitic stainless hlau, yog li tso cai rau tus tsim kom txuag tau qhov hnyav thiab ua rau cov hlau sib tw ntau dua thaum piv rau 316L lossis 317L.
