Alloy 904l Tube Resistant rau Intergranular Corrosion
Cov ntsiab lus siab chromium nyob rau hauv EN 1.4539 stainless hlau txhawb nqa thiab tuav cov yeeb yaj kiab passive uas tiv thaiv cov khoom hauv ntau qhov chaw corrosive. 904L tiv taus ntau dua rau nag lossis daus ntawm ferrite thiab sigma theem thaum txias thiab vuam dua li lwm yam molybdenum-muaj stainless hlau xws li 316L thiab 317L. Vim tias cov ntsiab lus qis qis tsis muaj kev pheej hmoo ntawm intergranular corrosion thaum txias lossis vuam, AISI 904l tuaj yeem siv rau ntawm qhov kub siab tshaj ntawm 450 degree.

AISI 904l Kev Kho Mob
SS 904l raj tau teev tseg los ntawm ASTM B677 muaj qhov ua tau zoo heev rau kub phosphoric acid. 904l ua rau qhov kev qhia tshwj xeeb no tuaj yeem tsim nyob rau hauv ob qho kev ua haujlwm kub lossis txias ua haujlwm. Tsis tas li ntawd, peb muab cov raj SS uas tau muab tshuaj kho, kho cua sov thiab tom qab ntawd quenched hauv dej los yog txias txias los ntawm lwm txoj kev.
