LawgB2 vs C276
Tshuaj Muaj Tshuaj
Hastelloy B2 yog ib npib tsib xee - molybdenum alloy uas cov molybdenum cov ntsiab lus muaj cov kev tiv thaiv tshwj xeeb kom txo cov xov xwm.
Hastelloy C276 yog npib tsib xee {{1} chromium - molybdenum {}} tungsten alloy. Molybdenum muab kev tiv thaiv kom txo ib puag ncig; Qhov kev sib ntxiv ntawm chromium muab rau oxidizing media; Thiab tungsten ntxiv rau cov alloy's tag nrho tsis kam rau pitting thiab corrose corrosion.
Corrosion tsis kam thiab cov ntawv thov
Alloy B2 ua tau zoo tshaj plaws nyob rau hauv hydrochloric acid ntawm txhua qhov ntau, nruab nrab ntawm cov sulfuric acid, thiab lwm yam tsis {oxidizing acid ib cheeb tsam. Nws yog feem ntau siv nyob rau hauv cov txheej txheem tshuaj lom neeg kov cov tshuaj txo ntau, xws li hydrochloric acid rov qab cov khoom siv thiab acetic acid cov khoom siv ntau lawm.
Alloy C276 Cov khoom pov thawj ua tau zoo heev corrosion tsis kam rau cov tshuaj chlorine roj, thiab cov tshuaj chloride, thiab cov tshuaj chloride zoo li cov cerric chloride thiab cupric chloride. Qhov no ua rau nws dav siv nyob rau hauv flue roj desulfurization tshuab, pulp tshuaj dawb, tshuaj lom neeg ib puag ncig.
Vuam thiab ua cov yam ntxwv
Tsis yog N10665's Weld Tshav Kub Kub - Cov chaw cuam tshuam nrog kev cuam tshuam nrog qee qhov ntsuas kub, uas tuaj yeem ua rau muaj kev ua tsis tau yooj yim.
Tsis yog N10276 cov ntsiab lus tsawg dua thiab cov khoom lag luam silicon txhim kho weldability, cia nws los tswj kev txhim kho corrosion zoo txawm nyob hauv lub xeev welded. Qhov no tshem tawm qhov xav tau rau post- weld daws kev kho thiab muaj kev tsim kho kom zoo thiab yooj yim heev. Tsis tas li ntawd, nws siab - kub lub zog thiab cov taub dej ntau tshaj ntawm B2, txuas ntxiv nws qhov ntsuas kub.
Hastelloy B2 VS C276:Yuav Xaiv Li Cas
Qhov kev txiav txim siab ntawm B2 thiab C276 nyob ntawm lub fundamently rau hom corrosive media koj tau cuam tshuam nrog:
Yog tias koj daim ntawv thov cuam tshuam txog cov ntshiab, tsis - ecidizing thiab kub, thiab tus nqi txiav txim siab, hastelloy b2 tej zaum yuav muaj tus nqi ntau dua- kev xaiv tau zoo.
Yog tias koj daim ntawv thov cuam tshuam nrog cov kev sib xyaw ua ke nrog cov kab mob oxidizing, lossis kev pheej hmoo c276 yuav yog qhov kev xaiv tau zoo dua.
LawgB2Tus nqi khoom
Tus nqi ntawm haastelloy b2 alloy yog cuam tshuam los ntawm cov khoom lag luam, cov khoom lag luam tshwj xeeb, kev ua lag luam thiab kev hloov pauv ntawm cov khoom siv raw.
TusNqe ntawm hastellloy b2 phaj / ntawvFeem ntau yog li $ 18 txog $ 50 rau ib phaus. Thickness, dav, thiab nto kev kho mob cuam tshuam tus nqi. Piv txwv li, nyias phaj los yog precision sawb, vim nws kev ua nyuaj, tuaj yeem ncav cuag cov nqi nyob ze lossis txawm nyob rau sab saud. Qee tus neeg muab khoom yuav hais cov nqi ntawm $ 2,500 rau $ 2,680 ib tev rau tej yam kev yuav khoom ntawm qee yam tshwj xeeb (xws li 4x8-taw txheem phaj).
TusTus nqi rau Hastellloy B2 Bar / Hloov Hlauyog nyob ntawm dav, xws li los ntawm kwv yees li $ 15 rau $ 50 rau ib phaus. Txoj kab uas hla yog tus nqi tseem ceeb tshaj plaws, nrog qhov loj dua uas muaj qhov loj dua {{} forged bar them ntau dua. Nws yog tsim nyog sau cia uas yuav ntim ntau yam uas cov tsev tus nqi. Piv txwv li, qee tus neeg xa khoom nyob ntawm $ 22 thiab $ 30 rau kev txiav txim tshaj 500 kilograms, thaum cov xaj xaj me tuaj yeem ncav tau $ 34 txog $ 36.
TusNqe ntawm Hastelloy B2 Yeeb Nkabfeem ntau muaj ntau npaum li cas los ntawm $ 15 txog $ 60 ib kilogram. Qhov sib txawv hauv cov txheej txheem ntau yam ntawm cov yeeb nkab uas muaj ntau yam xws li cov txheej txheem tuab thiab ua raws li ASTM B622 txhua tus txiav txim nqe nqi. {-} Ua raws li cov yeeb nkab uas tsis ua txhaum rau $ 30 txog $ 40 ib phaus.
Hastelloy B2 Vuam Rods thiab Cov Xov Toojfeem ntau tus nqi ntawm $ 15 thiab $ 21 ib kilogram. Tus nqi rau cov khoom no yuav nyob ntawm Alloy muaj pes tsawg leeg, lub cheeb, thiab ua tshwj xeeb.
Tag nrho cov lus hais tau zoo heev rau kev txiav txim tsawg kawg nkaus; small purchases in the kilogram range can cost significantly more than larger, tonnage-based orders. International Amer International nqi, tus nqi xa khoom, thiab cov nqi thauj khoom tseem ceeb tseem ua lub luag haujlwm tseem ceeb hauv kev ntsuas. Nws raug nquahu kom muab cov ncauj lus ntxaws ntxaws rau ntau cov neeg muag khoom thaum mus yuav cov lej.
