Kev sib piv ntawm 304 stainless hlau thiab Qib 2 titanium alloy
Kev sib piv ntawm 304 stainless hlau thiab Qib 2 titanium alloy
304 stainless hlau yog hnyav dua, pheej yig dua, thiab muaj thermal conductivity zoo dua; thaum Qib 2 titanium alloy yog sib dua, khav theeb zoo heev - rau - hnyav piv, superior corrosion kuj, thiab zoo heev biocompatibility, ua rau nws zoo tagnrho rau aerospace, marine, thiab kev kho mob cog daim ntaub ntawv. Txawm hais tias titanium alloy yog kim dua thiab nyuaj rau kev ua haujlwm, nws tseem yog qhov kev xaiv zoo tshaj plaws rau cov teb no, thaum stainless hlau yog qhov tsim nyog rau kev lag luam thiab cov khoom siv hauv chav ua noj.
Puas yog 304 stainless hlau xeb?
Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias thaum 304 stainless hlau tuaj yeem corrode, nws yuav tsis xeb nyob rau hauv ib txwm huab cua. Corrosion ntawm stainless hlau tsuas yog tshwm sim nyob rau hauv ntau nruj ib puag ncig los yog thaum cov hlau muaj impurities.
Stainless Hlau 304 yog ib qho dav dav -lub hom phiaj austenitic stainless hlau paub txog nws qhov zoo corrosion kuj, zoo heev formability, thiab weldability. Nws cov ntsiab lus tseem ceeb yog chromium-nickel alloy (kwv yees li 18% chromium thiab 8% npib tsib xee), ua kom pom kev ruaj ntseg hauv cov huab cua me me, dej tshiab, thiab ntau yam oxidizing media. Nws yog dav siv hauv chav ua noj, khoom noj khoom haus, kho kom zoo nkauj architectural, khoom siv hauv tsev, thiab cov khoom siv dav dav, ua rau nws siv ntau tshaj plaws thiab tus nqi - qib stainless hlau zoo. Txawm li cas los xij, nws tsis haum rau siab -concentration chloride lossis muaj zog txo cov kua qaub ib puag ncig.
Titanium Qib 2 yog cov khoom siv dav tshaj plaws hauv qib siab titanium ( - hom titanium alloy). Nws cov yam ntxwv tseem ceeb suav nrog kev tiv thaiv corrosion zoo heev (tshwj xeeb tshaj yog nyob rau hauv ib puag ncig chloride), zoo tag nrho cov khoom siv kho tshuab (qhov sib npaug ntawm lub zog thiab ductility), thiab zoo heev txias formability thiab weldability. Nws feem ntau yog siv rau hauv cov khoom siv tshuaj (cov khoom siv hluav taws xob, cov khoom siv hluav taws xob, cov khoom siv hluav taws xob), marine engineering, cov khoom siv kho mob, tsis yog -load-cov kabmob aerospace, thiab cov khoom siv. Nws yog cov khoom "workhorse" ntawm cov qib ntshiab titanium, ntsuas kev ua tau zoo, kev ua haujlwm, thiab tus nqi- ua tau zoo.
