Nyob rau hauv cov ntaub ntawv siv khoom lag luam,Stainless hlauthiabHastelloy alloyUa si lub luag haujlwm tseem ceeb vim lawv qhov tshwj xeeb corrosion tsis kam. Tus qub, hu ua "stainless acid - Txoj kev ua noj, thiab lwm thaj chaw ua zaub mov, muaj lwm txoj haujlwm tseem ceeb hauv engineering thiab marine engineering thiab marine tshuab. Thaum ob qho tib si yog corrosion - Cov ntaub ntawv resistant, lawv txawv nyob rau hauv lawv muaj pes tsawg leeg, kev ua tau zoo, thiab daim ntawv qhia txog kev ua yeeb yam. Kab lus no yuav soj ntsuam qhov sib txawv ntawm316L stainless hlauthiabHastelloy C276Alloy los ntawm tsib qhov kev xav: tshuaj lom neeg, cov khoom siv lub cev, thiab thaj chaw thov.

Tshuaj lom neeg sib txawv
- 316L stainless hlau: Stainless hlau yog ib tus hlau - saib alloy uas cov tub ntxhais kawm chromium (ntau dua los yog sib npaug). Chromium cov ntaub ntawv ntom xim oxide (cr₂o₃) ntawm cov hlau saum npoo, muab corrosion tsis kam.316L stainless hlau(16 - 12ni {{{{} 2.5mo} 2.5mo {}} molybdenum hlau (CR-NI-MO system). Qhov sib ntxiv ntawm molybdenum tau txhim kho ntau yam hloov kho pitt corrosion thiab yog siv dav hauv ib puag ncig dej hiav txwv.
- Hastelloy C276: Hastelloy C276yog nickel - based supalloy, feem ntau muaj ntau tshaj 50% npib tsib xee. Lub synergistic cuam tshuam ntawm molybdenum, chromium, tungsten, thiab lwm cov ntsiab lus muab rau cov chaw muaj kev tiv thaiv corrosion.

Cov Khoom Sib Txawv Rau Lub Cev
1. Corrosion Kuj
- 316L stainless hlau: Molybdenum txhim kho cov tshuaj chloride ion tsis kam, tab sis nws tseem corrodes loj hauv cov kua qaub muaj zog xws li 65% nitric acid.
- Hastelloy C276: Tus nqi corrosion nyob rau hauv boiling 65% nitric acid tsuas yog 0.01 mm / xyoo, 1/50 uas ntawm 316L. Tus nqi corrosion nyob rau hauv 10% hydrochloric acid yog 0.02 mm / xyoo, thaum 316L ua tiav tag nrho cov xwm txheej.
2. Cov Khoom Siv Neeg Kho Tshuab
- 316L stainless hlau: Tensile lub zog ntawm 520-620 mpa ntawm 40% -60 -60 -60%, ua rau nws haum rau kev sib nqus.
- C-276 Alloy: Chav chav kub tensile lub zog ntawm 730 mpa, elongation ntawm 40%. Nws tswj lub zog tensile ntawm 520 MPA ntawm 650 degree, thaum 316l lub zog poob rau 310 mpa ntawm tib qho kub.

Daim ntawv thov thaj chaw sib txawv
1. 316}} stainless hlau
- Marine engineering: 316 yog siv nyob rau hauv cov nkoj, cov khoom muaj nqis, thiab ntug dej hiav txwv kom tiv taus corrosion los ntawm high corroride ion siab nyob rau hauv seawater.
- Cov Khoom Siv Tshuaj: 316 Ua tau zoo tshaj qhov kev pabcuam lub neej ntawm cov khoom siv tshuaj lom neeg, reactors, thiab cov twj tso ua haujlwm hauv acidic lossis chlorine - muaj xov xwm.
- Cov Khoom Siv Kho Mob: 316 tseem siv cov khoom siv kho mob thiab kev phais cov cuab yeej siv uas xav tau cov peev txheej muaj kev tiv thaiv kev ua haujlwm siab.
- Cov Khoom Noj Khoom Haus Thiab Dej Haus: 316 Stainless Hlau Outperforms 304 hauv qee cov khoom noj khoom haus thiab ua haujlwm brewing ua haujlwm hauv cov chaw noo noo thiab muaj kev xeb.
2. Hastelloy C276 Kev Siv
- Tshuaj Txhuam Reactors thiab cov twj tso kua mis: C276 effectively prevents corrosion in piping and equipment in acidic, alkaline, and chlorine-containing environments.
- Marine engineering: C276 feem ntau siv nyob rau hauv cov nkoj, lub platform ntug dej, thiab cov cuab yeej tshuaj kom muaj zog los tiv thaiv kev txhim kho corrosion los ntawm cov salinity siab hauv dej hiav txwv.
- Roj thiab Roj Kev Lag Luam: C276 kom ntev - cov haujlwm ua haujlwm hauv cov khoom siv siab {2} {{} kub, thiab corrosive ib puag ncig.
