ASTM B 407 Cov khoom sivNiFeCr alloy kavyogsiab -kev ua tau zoo seamless rajua los ntawmNickel{0}}Iron-Chromium (NiFeCr) alloys. Lawvcorrosion kuj, siab -kub lub zog, thiab kev nyuaj siab-corrosion cracking kujua kom lawv zoo tagnrho raukev siv hluav taws xob nuclear tseem ceeb, qhov twg kev nyab xeeb, kev cia siab, thiab kev ua neej ntev yog qhov tseem ceeb.
Hauv cov nroj tsuag nuclear, cov khoom sib ntsibsiab -sab siab zog, ib puag ncig xov tooj cua, thiab thermal cycling, uaASTM B407 alloy yeeb nkab yog ib qho kev daws teeb meemrau piping, heat exchangers, thiab reactor systems.
Cov txiaj ntsig tseem ceeb hauv Nuclear Power Systems
High -Tsub Resistance:Haum rausteam thiab superheated kua thaujmus txog 593℃(1100℃F).
Corrosion Resistance:Zoo heev tiv thaivoxidizing thiab txo cov xov xwm, suav nrog siab - dej huv thiab chav dej.
Kev ntxhov siab -Corrosion Resistance:Nrogthermal cycling thiab hluav taws xob-ua rau muaj kev ntxhov siabtsis tawg.
Seamless Kev Tsim Kho:Xyuas kom meejsiab -siab ncaj nceesthiab xau- ua haujlwm dawb.
Lub neej ua haujlwm ntev:Txo kev tu thiab hloov hauvtseem ceeb nuclear cog systems.

Kev Tshawb Fawb & Kev Pov Hwm Zoo
Raunuclear - qib kev sivASTM B407 cov kav dej tau raug kuaj nruj:
Tshuaj ntsuam xyuas:Spectrometry kom ntseeg tau tias muaj pes tsawg leeg ua tau raws li ASTM cov qauv.
Mechanical Testing:Tensile, yield, thiab elongation pov thawj nyob rau hauv simulated nuclear tej yam kev mob.
Tsis yog -Kev Ntsuas Kev Puas Tsuaj (NDT):Ultrasonic, hydrostatic, thiab eddy kev kuaj tam sim no rau kev kuaj pom tsis raug.
Thib peb-Party Certification:Daim ntawv pov thawj zeb xeem (MTC), ISO 9001, thiab ua raws linuclear kev lag luam codes.
Traceability:Tag nrho cov batch traceability rau kev nyab xeeb thiab kev tswj xyuas.
