2205 Duplex Stainless hlau: lub zog thiab corrosion resistance combo

 

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. Cov kab ke no tsim cov microstructure nrog ntxhib 50% austenite thiab 50% ferrite, sib txuas cov cwj pwm zoo tshaj plaws ntawm ob qho tib si.

 

2205 ua li cas raws li lub zog?

2205 muaj lub zog tensile ntawm 620 {{{{4 4}}} 8 MPa, txog ob zaug ntawm cov ntawv thov hnyav uas yog qhov tseem ceeb yog qhov tseem ceeb.

 

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 nyob rau hauv ntau cov chaw ua pa, xws li dej hiav txwv.

 

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 qhov kev tsim kho kom zoo, tso cai rau khoov, dov, thiab lwm yam kev ua haujlwm tsis muaj kev ua haujlwm ntau dhau.

 

Nyob qhov twg 2205 feem ntau siv?

Pom nyob rau hauv cov roj thiab roj pipelines, cov tso tsheb hlau luam tshuaj, thiab offshore qauv. Nws kuj tseem siv nyob rau hauv cov nroj tsuag desalination thiab pulp thiab cov khoom lag luam ntawv uas ob lub zog thiab corrosion tsis kam yog qhov tseem ceeb heev.
