Cov Khoom Qhia Txog Khoom

Cov Cim Npe Khoom

ER 2209yog tsim los vuam cov hlau tsis xeb duplex xws li 2205 (UNS Number N31803). Lub zog tensile siab thiab kev tiv thaiv zoo dua rau kev ntxhov siab corrosion cracking thiab pitting piav qhia txog cov welds ntawm cov hlau no. Cov hlau no qis dua hauv ferrite piv rau cov hlau hauv paus kom tau txais kev txhim kho weldability.

ER 2553yog siv los vuam cov hlau tsis xeb duplex uas muaj kwv yees li 25% chromium. Nws muaj lub microstructure 'duplex' uas muaj cov austenite-ferrite matrix. Cov hlau duplex no yog tus cwj pwm los ntawm lub zog tensile siab, tiv taus kev ntxhov siab corrosion cracking thiab txhim kho kev tiv taus pitting.

ER 2594yog ib txoj hlau vuam superduplex. Tus lej Pitting Resistance Equivalent Number (PREN) yog tsawg kawg yog 40, yog li ntawd tso cai rau cov hlau vuam hu ua superduplex stainless hlau. Cov hlau vuam no muab cov tshuaj lom neeg sib phim thiab cov yam ntxwv khoom siv kho tshuab rau cov hlau superduplex xws li 2507 thiab Zeron 100 nrog rau cov hlau superduplex casting (ASTM A890). Cov hlau vuam no yog overalloyed 2-3 feem pua hauv Nickel los muab qhov zoo tshaj plaws ferrite / austenite piv hauv qhov vuam tiav. Cov qauv no ua rau muaj kev tensile siab thiab lub zog tso zis nrog rau kev tiv thaiv zoo dua rau SCC thiab pitting corrosion.
