434 Stainless hlau
Ferritic stainless hlau 434 muaj 12 feem pua rau 30 feem pua ntawm cov ntsiab lus chromium. Nrog ntau chromium tam sim no, cov hlau yuav muaj zog dua, weldable, thiab corrosion-resistant. Nws kuj ua tau zoo dua lwm hom stainless hlau nyob rau hauv cov nqe lus ntawm kev tiv thaiv chloride-kev nyuaj siab corrosion. Nyob rau hauv tej chaw nrog lub teeb corrosion, nws muaj zoo resilience. Nws muaj zog tiv thaiv tshav kub thiab zoo scaling kuj mus txog 815 degree (1500 degree F). Qib zoo ntawm 430 steel hu ua 434 (18Cr{10}}Mo) yog siv los ua cov khoom siv sab nrauv rau cov tsheb vim nws muaj ntsev ntau dua li 430 steel.
