Mos Annealing
Tshav kub rau 820-860oC, txias maj mam hauv qhov cub. Qhov no yuav tsim qhov siab tshaj plaws Brinell hardness ntawm 269.
Hardening
Harden los ntawm qhov kub ntawm 1000-1050oC ua raws li cov roj los yog quenching. Hardness tom qab quenching yog min. 58 HRC.
Tempering
Tempering kub: Saib cov ntaub ntawv hauv qab no.
Tempering Kub (oC) vs. Hardness (HRC)
Tempering Diagram
Forging
Pre-heat rau 760oC, tom qab ntawd maj mam nce mus rau 1038-1204oC ua ntej yuav mus. Tsis txhob ua cov khoom no qis dua 927oC. Txias cov khoom maj mam tom qab ua hauj lwm thiab ib zaug nyob rau hauv chav tsev kub, anneal tag nrho.
Machineability
Qhov zoo tshaj plaws machined nyob rau hauv lub annealed mob. Cov tawv tawv, stringy chips tuaj yeem ua tau zoo tshaj plaws los ntawm kev siv cov chip breakers. Carbide lossis ceramic tooling yog pom zoo.
Ua haujlwm txias
Cov alloy no suav hais tias tsuas yog me ntsis txias ua haujlwm tau los ntawm kev coj ua.
Corrosion Resistance
Resistant rau ntau yam xov xwm xws li dej tshiab, chav, roj av thiab cawv. Cov khoom siv tsis pom zoo kom siv rau hauv qhov mob annealed vim nws tuaj yeem xeb. Cov txheej txheem passivation raug pom zoo los txhim kho corrosion kuj nyob rau hauv quenched thiab tempered daim ntawv. HT pom zoo kom tau txais qhov zoo tshaj plaws corrosion kuj. Nyob rau hauv rooj plaub no raws li kev pom zoo uas tau txais los ntawm qhov kub thiab txias tempering nrog daim iav tiav nto. Lub 440 steel tsis pom zoo kom siv rau hauv qhov ntsuas kub siab tshaj 400oC. Corrosion tsis kam yog txo thaum siv nyob rau hauv siab temperarure mob.
Vuam
Cov hlau no tsis yog feem ntau welded vim nws nyiam cua tawv. Yog tias nws yuav tsum tau welded, preheat rau 260oC thiab tom qab vuam kho ntawm 732-760oC rau 6 teev tom qab ntawd los ntawm qhov cub qeeb qeeb kom tsis txhob tawg. Siv cov hlau zoo sib xws.
