Stainless Hlau Phaj Raws li SS440B
Ib qho kev ua tau zoo martensitic stainless hlau nrog 16 feem pua -18 feem pua chromium alloying Cheebtsam, 440B muaj zoo heev toughness, corrosion kuj, thiab hardness. Nws kuj muaj qhov zoo resilience. Nws qhov tsis zoo thaum sib tsoo yog tias nws yog me ntsis khov thiab sov sai sai, tab sis nws grinds yooj yim dua li cov pa roj carbon steel thiab ua rau txiav cov ntaub ntawv nrog txhais tes pom qhov yooj yim dua. Stainless hlau 440B yog tawv thiab nyuaj dua li cov hlau 440C thiab 440A ua ke. Txiav, ntsuas, cov kabmob, thiab cov cuab yeej valve yog txhua yam ua los ntawm nws.
Vim hais tias 440B muaj lub cev-qhov nruab nrab qhov cubic lub koom haum, nws lub zog txo qis heev ntawm qhov kub thiab txias. Txawm li cas los xij, qis dua 600 degree, nws muaj qhov muaj zog tshaj qhov kub thiab txias zog ntawm lwm yam stainless hlau.
