dab tsi duplex 2205 stainless hlau phaj yuav siv los?

Date:Jul 12, 2019

2205 duplex stainless hlau yog nitrogen-ntxiv duplex stainless hlau (raug xa mus rau 2205 duplex steel hlau). Duplex stainless hlau 2205 alloy yog duplex stainless hlau muaj li 21% chromium, 2.5% molybdenum thiab 4.5% npib tsib xee-nitrogen alloy.Qhov khoom hauv tsev 2205 stainless hlau cov khoom muaj xws li 2205 stainless hlau tubes thiab 2205 duplex stainless hlau seamless tubes; 2205 duplex stainless hlau los xij, 2205 tus pas hlau tsis muaj, tsis nco qab, ua yeeb thiab txhav.

Nws cov tshuab txhua yam yog raws li nram no:

Cov yam ntxwv ua rau ntawm 2205 duplex steel tsim nyob ntawm seb cov khoom lag luam thiab kev kho cua sov zaum kawg. Hauv qhov kub ntawm -50 degrees rau 280 degrees, duplex stainless hlau muaj cov yam ntxwv zoo txhua yam. Thaum cov hlau duplex raug rau qhov kub siab ntau dua 300 degrees rau lub sijhawm ntev, nws lub microstructure yuav hloov. Piv nrog austenitic steels, duplex steels thiab super duplex steel puag cov ntaub ntawv muaj centripetal tsis kam mus rau pitting thiab tawg corrosion, tab sis feem ntau muaj zoo heev tiv thaiv kev nyuaj siab corrosion ntawm cov organic acids. Nws yog qhov paub zoo hauv kev lag luam los hais txog pitting resistance qib raws li pitting resistance sib npaug nqi PREN.

Mechanical machinability

Ntawm kev siv lub tshuab siab, tus pub noj thiab txiav ceev ntawm 2205 alloy yog tib yam li 316L. Yog tias siv rab riam carbonized siv, kev txiav tawm nrawm yog txo kwv yees li 20% piv rau 316L, thiab kev ua haujlwm ntawm lub tshuab thiab nws cov khoom sib xyaw ua lub luag haujlwm tseem ceeb ntawm no.

Cov kev kho cua sov

Lub zog 2205 yuav tsum tau annealed ntawm qhov kub tsawg kawg ntawm 1900 ° F thiab tom qab ntawd txias txias rau dej quenching. Cov kev kho mob no tau siv rau cov tshuaj tiv thaiv annealing thiab kev ntxhov siab kom nyob taus. Kev kho mob kev ntxhov siab, xws li nyob rau qhov kub thiab qis tshaj 1900 ° F, nyhav yuav ua rau muaj nag lossis daus ntawm cov phom lossis cov hlau tsis huv.
