718h pwm hlau yog yas pwm hlau nrog Suav hom 3Cr2NiMo. Lub hom phiaj tseem ceeb ntawm kev txhim kho P20 pwm hlau, 718h hardness siab dua li ntawm P20 pwm hlau, ua tau raws li qhov xav tau ntawm kev lag luam hauv tsev. Nws yog ib hom steel qib ntawm feem ntau siv dav-lub hom phiaj yas pwm steel, feem ntau hu ua advanced yas pwm steel. Tshiab tsim tshiab qib steel feem ntau siv nws ua piv txwv qauv.
718H steel yog cov yas pwm yas ua ntej ua los ntawm Yishengbai hauv Sweden. Nws yog lub tshuab nqus tsev melted chromium, npib tsib xee, thiab molybdenum alloy steel nrog kev huv huv, zoo heev uniformity, thiab zoo heev polishing thiab photolithography zog. Pre hardened steel kuj tseem siv tau rau hauv pwm chamber yam tsis muaj quenching, thiab cov flange tuaj yeem ua nplaim taws quenched thiab hardened, nrog hardness txog li 52HRC.
Cov hlau no tsis xav tau kev kho cua sov, uas tuaj yeem ua rau lub voj voog tsim pwm, txo tus nqi ntawm cov pwm, thiab ua kom cov pwm yooj yim hloov kho lossis kho. Nitriding thiab hardening kev kho mob tuaj yeem siv los txhim kho qhov tawv tawv thiab hnav tsis kam ntawm pwm.
Cov xwm txheej muab khoom
Ua ntej hardness, hardness 330 ~ 370HBW
tshuaj muaj pes tsawg leeg
Piv txwv ntawm cov tshuaj muaj pes tsawg leeg (feem ntau) ntawm cov hlau no: C{{0}}.37 feem pua , Cr2.00 feem pua , Mn1.40 feem pua , Si0.30 feem pua , Mo0.20 feem pua , Ni1.00 feem pua
