Puas yog 1.4401 stainless hlau siv tau rau hauv cov khoom siv hluav taws xob nuclear fais fab?

☢️ Tuaj yeem 1.4401 stainless hlau siv rau hauv cov khoom siv hluav taws xob nuclear fais fab?

1.4401 Cov hlau stainless (en x5cnimo {3}} 31), tseem muaj ib tus neeg siv dav hlau stainless hlau muaj txiaj ntsig rau nws corrosion tsis kam thiab tshuab zog. Tab sis tuaj yeem tau 1.4401 yuav siv nyob rau hauv lub zog hluav taws xob cog cov ntawv thov?

✅ Yog - tab sis nrog kev txwv

Thaum 1.4401 stainless hlau tsis tau faib ua cov khoom siv nuclear-uclear-, nws qee zaum siv hauv cov hluav taws xob nuclear.

General Corrosion

🔹pitting thiab crevice corrosion (vim mo cov ntsiab lus)

🔹hhal tam sim no (txog li ~ 870 degree sib deev)

🔹Howersever, rau cov chaw ua haujlwm tseem ceeb, cov pa taws hluav taws xob siab, lossis cov kev nyab xeeb-kev kawm, 1.440 yog feem ntau tsis txaus vim:

🔹lack ntawm nruj impurity tswj (piv txwv li, cobalt, sulfur)

🔹no muaj ntawv pov thawj ucear traceabability (piv txwv li, rcc-m, ASME III chav kawm 1 tsis lees paub)

🔹potential sensitization nyob rau hauv neuton flux

🏗️ Qhov twg 1.4401 tuaj yeem siv rau hauv cov ntawv thov nuclear

Txias dej tshuab (tsis yog-tub ntxhais)

Ntu Piping

Cov Txheej Txheem Txheej Txheem thiab Cov Khoom Siv

Tsis-luam yeeb ntawm chaw tso tsheb hlau luam

Yuav tsum txheeb xyuas RCC-M, ASME III, lossis KTA 3201 yog tias daim ntawv thov kev lees paub txog kev lag luam nuclear.
