GENERAL PROPERTIES
Stainless hlau yog cov hlau alloy siab uas muaj kev tiv thaiv corrosion siab piv rau lwm cov hlau vim tias 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 pab pawg ntawm stainless hlau yog nag lossis daus-hardened steels. Lawv yog cov sib xyaw ua ke ntawm martensitic thiab austenitic steels.
Qib 440C stainless hlau yog lub siab carbon martensitic stainless hlau. Nws muaj lub zog siab, nruab nrab corrosion kuj, thiab zoo hardness thiab hnav tsis kam. Qib 440C muaj peev xwm ua tau, tom qab kev kho cua sov, lub zog siab tshaj plaws, hardness thiab hnav tsis kam ntawm tag nrho cov hlau tsis muaj hlau. Nws cov ntsiab lus carbon siab heev yog lub luag haujlwm rau cov yam ntxwv no, uas ua rau 440C tshwj xeeb rau cov ntawv thov xws li pob bearings thiab valve qhov chaw.
APPLICATIONS
Cov ntawv thov ib txwm muaj xws li:
Rolling element bearings
Valve rooj
High quality riam hniav
Cov cuab yeej phais
Chisels

CORROSION RESISTANCE
Zoo tiv taus huab cua, dej tshiab, khoom noj, alkalies thiab me ntsis acids. Qhov zoo tshaj plaws nyob rau hauv hardened thiab tempered thiab passivated mob. Ib tug polished nto kuj pab.
Kev tiv thaiv corrosion ntawm qib 440C kwv yees li ntawm qib 304 hauv ntau qhov chaw.
KEV KHO MOB
Tsis pom zoo rau kev siv nyob rau hauv qhov kub siab tshaj qhov ntsuas kub ntawm qhov ntsuas kub, vim tias txo qis hauv cov khoom siv hluav taws xob los ntawm over-tempering.
Kev kho cua sov
Annealing - Tag nrho cov anneal - 850-900 degree, qeeb cua sov kom txias txog li 600 degree thiab ces cua txias. Sub-critical Annealing – 735-785 degree thiab qeeb cua sov txias.
Hardening - Thaum tshav kub kub mus rau 1010-1065 degree, ua raws li los ntawm quenching nyob rau hauv cov roj sov los yog cua. Roj quenching yog tsim nyog rau cov seem hnyav. Tam sim ntawd npau taws ntawm 150-370 degree kom tau txais ntau yam ntawm hardness qhov tseem ceeb thiab txhua yam khoom raws li qhia hauv lub rooj nrog.
Tempering nyob rau hauv ntau yam 425-565 degree yog yuav tsum tau zam vim yog txo qhov cuam tshuam tsis kam thiab corrosion kuj. Tempering nyob rau hauv ntau yam 590-675 degree ua rau qis hardness (cov khoom ua machinable) thiab muaj kev cuam tshuam siab.
WELDING
Yog tias vuam yog tsim nyog ua ntej cua sov ntawm 250 degree thiab ua raws li vuam nrog ib tug tag nrho anneal. Qib 420 muab tub lim yuav muab lub siab hardness weld (txawm tias tsis siab li 440C), tab sis 309 lossis 310 yuav tsim cov welds muag nrog ntau dua ductility.
MACHINING
Nyob rau hauv cov mob annealed qib no kuj yooj yim machined; kwv yees li tib yam li rau kev kub ceev steel. Chips yog tawv thiab stringy yog li chip breakers tseem ceeb. Yog tias cov qib no hardened machining yuav nyuaj dua thiab tej zaum yuav ua tsis tau.
