Alloy 20 Phaj N08020 Ntawv Cool
ASTM B463 tsis yog N08020 daim ntawv tuaj yeem ua los ntawm kub lossis txias dov. Cov ntawv no muaj lub zog zoo heev thiab tuaj yeem ua tau kom tau raws li qhov yuav tsum tau ua ntawm qhov kub thiab txias thiab kub siab. 2.4660 alloy 20 daim ntawv ntseeg tau ntseeg tau thiab siv sijhawm ntev.
Alloy 20 stainless hlau sawb tau zoo heev rau intergranular corrosion thiab acid-inducting tawg. Cov hlua no tuaj hauv cov tawv tawv nyias thiab ntau thiab tsawg. Nws muaj qhov ua tau zoo heev rau kev tsim tsa-Up, pitting thiab crevice corrosion hauv tshuaj muaj chlorides, sulfuric acid, phosphoric acid thiab nitric acid. Qhov no txhais tau tias nws yog qhov muaj siab heev rau cov chloride kev ntxhov siab corrosion. Qhov no Austenitic Nickel Alloy feem ntau yog siv rau kev ntxhov siab corrosion lossis cov kev daws teeb meem uas yuav tshwm sim nrog lwm cov hlau stainless xws li 316L. Muaj tshwj xeeb tsim rau siv nyob rau hauv muaj cov sulfuric acid thiab tiv thaiv pitting, chloride thiab sulfuric acid corrosion.
