Ib qho ntawm cov lus nug uas nquag nug thaum muas duplex stainless hlau tuav yog: Puas yog 1.4462 stainless hlau sib nqus? Cov khoom sib nqus ntawm 1.4462 (tseem hu ua Duplex 2205 stainless hlau) yog qhov tseem ceeb rau cov kws tsim khoom, cov neeg saib xyuas kev yuav khoom, thiab kawg - cov neeg siv, tshwj xeeb tshaj yog nyob rau hauv kev lag luam xws li tshuaj lom neeg, marine, shipbuilding, thiab roj thiab roj.
Kab lus no yuav piav qhia vim li cas 1.4462 stainless hlau yog hlau nplaum, nws cov hlau nplaum muaj zog npaum li cas, thiab seb nws cov hlau nplaum puas cuam tshuam rau nws qhov kev ua tau zoo lossis qhov zoo.
Dab tsi yog 1.4462 Stainless Hlau Bar?
1.4462 stainless hlau bar yog siab - zog, corrosion- resistant duplex stainless hlau (tseem hu ua UNS S31803 lossis 2205) uas muab cov khoom ntawm ob qho tib si austenitic thiab ferritic steels, muab kev tiv thaiv zoo heev rau pitting thiab kev ntxhov siab corrosion tawg, ua rau nws zoo tagnrho rau kev thov ib puag ncig marine, roj thiab kev siv tshuaj lom neeg. Nws cov qauv tshwj xeeb muab txog ob npaug ntawm qhov kev tawm dag zog ntawm cov qauv austenitic steels, ua ke nrog cov weldability zoo thiab hnav tsis kam.
Puas yog 1.4462 Stainless Hlau Bar Sib Nqus?
1.4462 stainless hlau rods muaj cov khoom sib nqus sib nqus. Lawv yog cov hlau nplaum ntau dua li austenitic stainless hlau (304, 316), tab sis tsawg sib nqus dua li ferritic lossis martensitic stainless hlau.
Hauv kev siv tswv yim: cov hlau nplaum tuaj yeem nyiam rau 1.4462 stainless hlau rods. Cov lus teb sib nqus yuav txawv me ntsis nyob ntawm kev kho cua sov thiab kev ua haujlwm.
Puas Magnetism cuam tshuam rau kev ua tau zoo ntawm 1.4462?
Tsis yog. Magnetism TSIS txo qhov kev ua tau zoo lossis zoo.
Cov khoom sib nqus:
❌ Tsis txhais hais tias tsis zoo corrosion kuj
❌ Tsis qhia cov khoom tsis raug
❌ Tsis cuam tshuam rau txhua yam muaj zog
Qhov tseeb, theem ferritic uas ua rau cov hlau nplaum kuj tseem ua rau:
Ntau zog tawm los
Zoo dua tiv thaiv kev ntxhov siab corrosion cracking
