Kev Piav Qhia Luv:
UNS S44000 Cov Tuav Tiaj, SS 440 Cov Tuav Tiaj, Cov Hlau Stainless 440 Cov Tuav Tiaj Tus Neeg Muag Khoom, Chaw Tsim Khoom thiab Tus Neeg Xa Khoom Tawm Hauv Suav Teb.
Cov hlau tsis xeb yog cov hlau uas muaj cov hlau sib xyaw ua ke ntau uas muaj kev tiv thaiv xeb zoo dua li lwm cov hlau vim muaj ntau cov chromium. Raws li lawv cov qauv crystalline, lawv tau muab faib ua peb hom xws li ferritic, austenitic, thiab martensitic steels. Lwm pawg ntawm cov hlau tsis xeb yog cov hlau uas tau ua kom tawv. Lawv yog kev sib xyaw ua ke ntawm cov hlau martensitic thiab austenitic. Qib 440C stainless hlau yog cov hlau tsis xeb martensitic uas muaj cov pa roj carbon ntau. Nws muaj lub zog siab, tiv thaiv xeb nruab nrab, thiab muaj zog thiab hnav tsis kam. Qib 440C muaj peev xwm ua tiav, tom qab kho cua sov, qhov muaj zog tshaj plaws, tawv thiab hnav tsis kam ntawm txhua cov hlau tsis xeb. Nws cov pa roj carbon ntau heev yog lub luag haujlwm rau cov yam ntxwv no, uas ua rau 440C tshwj xeeb tshaj yog rau cov ntawv thov xws li cov kabmob pob thiab cov khoom siv valve.
