40Cr kub dov steel puag ncig tuav

40Cr alloy structural steel muaj zog tensile ntau dua, tawm los lub zog thiab hardenability tshaj li No. 40 steel, tab sis nws cov weldability yog txwv thiab muaj ib tug nyiam tsim cov kab nrib pleb. 40Cr yog nruab nrab carbon modulated steel, txias taub hau tuag steel. Cov hlau yog tus nqi nruab nrab thiab yooj yim rau kev ua haujlwm. Tom qab kev kho cua sov kom zoo, qee qhov toughness, plasticity thiab hnav tsis kam tuaj yeem tau txais. Normalizing tuaj yeem txhawb cov spheroidization ntawm cov qauv thiab txhim kho qhov kev ua tau zoo ntawm qhov khoob nrog lub hardness tsawg dua 160HBS. Tempering ntawm qhov kub ntawm 550 ~ 570 ℃, cov hlau muaj cov khoom siv zoo tshaj plaws. Lub hardenability ntawm cov hlau no yog siab tshaj li ntawm 45 steel, thiab nws yog haum rau deg hardening kev kho mob xws li high zaus quenching thiab nplaim quenching. Tom qab quenching thiab tempering, 40Cr steel yog siv los tsim cov khoom siv hauv nruab nrab thiab nruab nrab ceev, xws li lub tsheb kauj vab knuckles, rear ib nrab shafts thiab gears, shafts, worms, spline shafts, sab saum toj tes tsho ntawm cov cuab yeej siv tshuab, thiab lwm yam.; Tom qab quenching thiab Tom qab tempering ntawm nruab nrab kub, nws yog siv los tsim cov khoom uas dais siab load, cuam tshuam thiab nruab nrab ceev ua hauj lwm, xws li zog, spindles, roj twj tso kua mis rotors, sliders, dab tshos, thiab lwm yam .; Tom qab quenching thiab tsis kub tempering, nws yog siv los tsim cov khoom uas dais hnyav loads thiab tsis tshua muaj kev cuam tshuam Thiab qhov chaw nrog hnav tsis kam thiab cov khoom thickness ntawm tus ntoo khaub lig seem hauv qab 25 hli, xws li worms, spindles, shafts, dab tshos, thiab lwm yam .; Tom qab quenching thiab tempering thiab high-frequency nto quenching, lawv yog siv los tsim cov hardness siab thiab hnav tsis kam. Cov khoom uas muaj kev cuam tshuam zoo, xws li lub zog, lub tes tsho, shafts, lub ntsiab shafts, crankshafts, spindles, pins, txuas rods, screws, ceev, intake valves, thiab lwm yam. Tsis tas li ntawd, cov hlau no tsim nyog rau kev tsim ntau yam kis tau tus mob rau carbonitriding, xws li raws li lub zog thiab shafts nrog loj diameters thiab zoo tsis tshua muaj kub toughness.

Cov khoom siv ntawm annealed GB 40CR alloy steel yog teev nyob rau hauv cov lus hauv qab no

Kev kho cua sov ntsig txog

• Annealing ntawm 40CR Alloy steel qauv

Maj mam rhuab mus rau 850 ℃ thiab cia lub sij hawm txaus, cia cov hlau kom huv si, ces txias maj mam nyob rau hauv lub cub tawg. 40CR alloy steel yuav tau MAX 250 HB (Brinell hardness).

• Hardening ntawm 40CR Alloy qauv steel

Tshav kub maj mam mus rau 880-920 ° C, Tom qab txaus soaking ntawm no kub quench nyob rau hauv cov roj. Kub kom sai li sai tau thaum cov cuab yeej ncav cuag chav sov.
