Alloy 20 vs. Hastelloy: Qhov twg yog Cov Hlau Zoo Tshaj?

 

Alloy 20 thiab Hastelloy yog ob qho ntawm cov khoom siv nrov tshaj plaws siv hauv kev tsim khoom. Lawv ob leeg muaj qhov zoo thiab qhov tsis zoo, tab sis ob peb qhov sib txawv tseem ceeb ua rau ib qho zoo dua rau lwm tus, nyob ntawm kev siv. Kab lus no yuav tham txog vim li cas Alloy 20 yuav zoo dua rau qee cov ntawv thov thiab vim li cas Hastelloy yuav yog qhov kev xaiv zoo dua hauv lwm qhov xwm txheej.

Alloy 20

Alloy 20 yog nickel-chromium-molybdenum stainless hlau alloy uas tau tsim los siv rau hauv kev lag luam tshuaj. Cov hlau muaj kev tiv thaiv zoo heev rau ntau yam tshuaj, suav nrog sulfuric acid, phosphoric acid, thiab nitric acid. Tsis tas li ntawd, Alloy 20 muaj zoo weldability thiab formability zog.

Hastelloy

Hastelloy yog ib tsev neeg ntawm nickel-chromium-molybdenum alloys uas tau tsim los siv rau hauv kev lag luam tshuaj. Cov alloys muaj kev tiv thaiv zoo heev rau ntau yam tshuaj, suav nrog sulfuric acid, phosphoric acid, thiab nitric acid. Tsis tas li ntawd, Hastelloy alloys muaj zoo weldability thiab formability zog.

Alloy 20 vs Hastelloy:Qhov txawv yog dab tsi?

Ob lub alloys yog tsim los ntawm nickel-chromium-molybdenum (NiCrMo), tab sis lawv txawv me ntsis hauv lawv cov muaj pes tsawg leeg - tshwj xeeb, Alloy 20 muaj tooj liab thaum Hastelloy tsis. Qhov sib txawv no cuam tshuam rau lawv cov yam ntxwv ua tau zoo thiab ua rau lawv haum rau kev siv sib txawv.

Alloy 20 paub txog nws cov khoom tiv thaiv corrosion zoo heev thiab tuaj yeem tiv taus kub txog li 1000 degree F (538 degree). Nws kuj tseem tiv taus cov sulfuric acid, ua rau nws yog ib qho khoom siv zoo tshaj plaws rau kev siv tshuaj hauv cov nroj tsuag tshuaj lossis cov nroj tsuag fais fab uas xav tau cov ntaub ntawv corrosion-resistant. Txawm li cas los xij, nws tsis muaj zog li lwm cov hlau, xws li hastelloy, yog li nws yuav tsis yog cov khoom siv zoo tshaj plaws rau cov ntawv thov uas lub zog yog qhov tseem ceeb.

Ntawm qhov tod tes, hastelloy muaj lub zog ntau dua li alloy 20 tab sis tsis yog li tiv taus corrosion los yog kub heev. Nws tseem yog ib qho kev xaiv zoo rau ntau daim ntawv thov vim nws lub zog thiab muaj peev xwm tiv taus qhov nruab nrab kub txog li 1500 degree F (815 degree). Hastelloy kuj muaj qhov zoo weldability thiab formability, ua rau nws yooj yim rau kev tsim rau hauv cov khoom tiav dua lwm yam hlau xws li stainless hlau los yog titanium.

 

Kev sib xyaw

Qhov sib txawv loj tshaj plaws ntawm Alloy 20 thiab Hastelloy yog lawv cov khoom xyaw. Alloy 20 muaj carbon, thaum Hastelloy tsis. Qhov no ua rau Alloy 20 muaj kev cuam tshuam ntau rau carbide nag lossis daus, uas tuaj yeem txo nws cov corrosion kuj. Tsis tas li ntawd, Alloy 20 muaj silicon, uas tuaj yeem txhim kho nws cov weldability tab sis kuj tuaj yeem ua rau kub tawg. Hastelloy tsis muaj silicon, ua rau nws tsis tshua muaj kev kub ntxhov thaum vuam.

 

Cov khoom

Vim lawv qhov sib txawv, Alloy 20 thiab Hastelloy muaj cov khoom sib txawv. Alloy 20 yog qhov tiv taus corrosion ntau dua li Hastelloy tab sis kuj tseem cuam tshuam rau carbide nag lossis daus. Tsis tas li ntawd, Alloy 20 muaj qhov vuam zoo dua li Hastelloy tab sis kuj tseem yuav muaj kev kub kub tawg thaum vuam.

 

Koj yuav tsum siv qhov twg?

Kev txiav txim siab seb puas yuav siv Alloy 20 lossis Hastelloy nyob ntawm daim ntawv thov. Yog tias kev tiv thaiv corrosion yog qhov tseem ceeb tshaj plaws, ces Hastelloy yuav yog qhov kev xaiv zoo dua. Txawm li cas los xij, yog tias weldability tseem ceeb dua, ces Alloy 20 yuav yog qhov kev xaiv zoo dua.
