LDX 2101 Txheej txheem cej luam
LDX 2101 yog qhov tsawg-alloyed, qhov laj thawj hom ntshiv duplex stainless hlau. Nws muaj cov yam ntxwv xws li cov tshuab muaj zog siab, zoo ib yam li ntawm lwm cov hlau duplex, thiab zoo corrosion kuj. Piv nrog rau 300 series stainless hlau, 2101 duplex stainless muab zoo dua lub zog thiab ntau dua chloride kev nyuaj siab corrosion cracking tsis kam.
Kev siv cov manganese kom zoo rau ferrite-austenite theem sib npaug, thaum tso cai txo qis hauv cov ntsiab lus nickel. Raws li qhov tshwm sim, LDX 2101 yog luv nqi sib tw nrog 304 L thiab 316 L stainless hlau. Vim tias nws cov ntsiab lus me me uas tsis tshua muaj siab, nws tsis tshua muaj qhov los nag ntawm ntu intermetallic dua li lwm cov hlau duplex.
Corrosion kuj
Kev txhim kho corrosion ntawm LDX 2101 feem ntau yog qhov zoo, thiab yog li tsim nyog siv rau hauv kev siv dav hauv kev siv dav dav thiab ib puag ncig. Tsim nyog rau nws cov qauv duplex, LDX 2101 muaj qhov ua tau zoo rau kev cuam tshuam corrosion tawg. Nws tseem muaj kev txhim kho corrosion piv rau 304 L thiab 316 L stainless hlau, ua rau nws tus neeg sib tw zoo tshaj los hloov 300 series stainless hauv ntau cov kev siv.
Dab tsi yog cov yam ntxwv ntawm LDX 2101?
• Muaj peev xwm tiv taus chloride tawg siab corrosion cracking
• Cov tshuaj Chloride pitting thiab cov nplawm kev kho xeb tuaj yeem sib piv rau 316 L stainless
• Zoo dav corrosion kuj
• Lub zog muaj zog
• Zoo sulfide kev nyuaj siab corrosion kuj
• Lub tshuab tau zoo thiab weldability
