2205 Duplex Stainless hlau: lub zog thiab corrosion thiab corrosion- tiv taus txhua {2} rounder

 

Dab tsi txhais tau 2205 cov tshuaj muaj pes tsawg leeg?

Nws muaj 21-23% chromium, 4.5-6.5% npib tsib xee, 2.5-3.5% molybdenum, thiab 0.08-0.20% nitrogen. Qhov no muaj pes tsawg leeg tau tshwm sim nyob rau hauv microstructure uas yog kwv yees 50% Austenite thiab 50% ferrite.

 

2205 ua li cas raws li lub zog?

2205 muaj lub zog tensile siab ntawm 620 {{{4 4}} 8 MPa, uas yog hais txog ob zaug ntawm cov khoom siv tsis zoo li 304, ua rau nws zoo tagnrho rau cov ntawv thov hnyav.

 

Dab tsi yog nws corrosion resistance muaj zog?

Nws muaj kev tiv thaiv zoo heev rau pitting, crevice corrosion, thiab kev nyuaj siab corrosion tawg, tshwj xeeb tshaj yog hauv chloride {{}}} muaj ib puag ncig. Nws corrosion tsis kam yog zoo dua rau 316L hauv ntau qhov kev nce qib.

 

Yuav ua li cas 2205 kov fabrication thiab vuam?

2205 yog weldable, tab sis cov tswv yim zoo yog xav tau los tswj kev sib npaug ntawm kev txhawb nqa ntawm theem thiab Ferrite theem. Nws muaj cov kev tsim nyog zoo, tso cai rau khoov, dov, thiab lwm yam kev ua haujlwm.

 

Dab tsi yog 2205 tus ntawv thov raug?

Feem ntau siv nyob rau hauv cov roj thiab roj pipelines, cov tso tsheb hlau luam tshuaj lom neeg, thiab sab nrauv qauv. Nws kuj tseem pom nyob hauv cov nroj tsuag zoo nkauj thiab pulp thiab cov ntawv kev lag luam hauv qhov chaw muaj zog thiab corrosion tsis kam yog qhov tseem ceeb heev.
