SKS3 cov cuab yeej steel Cov lus qhia ntxaws
SKS3 cov cuab yeej hlau yog lub npe hu ua "tsis yog-deformation steel", tab sis kev tsim ntawm lub network ntawm carbides yog rhiab dua. Nws yog tsuas yog siv rau kev txiav cov cuab yeej thiab ntsuas cov cuab yeej nrog me me deformation, ntev thiab complex zoo, thiab high-precision txias stamping tuag (xws li xuas nrig ntaus tuag, stamping tuag, dabtsi yog khoov tuag, kos duab tuag, xuas nrig ntaus, xov tuag thiab lwm yam khoom siv tuag. ) thaum quenching.
Kev siv cov cuab yeej SKS3 steel
1, dav siv nyob rau hauv ua lub thickness ntawm tsis ntau tshaj 8 hli punching tuag, stamping tuag, dabtsi yog khoov tuag, xov tuag.
2, gauges, ntsuas cov cuab yeej, cov cuab yeej ua haujlwm ntoo thiab tshuab dhos thimble, thiab lwm yam.
3, ua kev qhia bushing, thimble, tuag, hlau koob, thiab lwm yam.
SKS3 yog cov hlau alloy rau cov pwm ua haujlwm txias.
Lub ntsiab tsis zoo ntawm SKS3 cuab yeej steel yog raws li nram no
Cov khoom xyaw tseem ceeb (%)

Physical/mechanical Properties
Hardness: annealing hardness Tsawg dua los yog sib npaug rau 217HB; Quenching hardness Ntau dua los yog sib npaug rau 60HRC.
Kev kho cua sov txheej txheem specification
Quenching: Ua ntej preheat rau 550-650 degree C, thiab tom qab ntawd kub rau 800-850 degree C, hardening hauv roj.
Tempering: cua sov mus rau 150-200 degree C, nyob ntawm qhov ntsuas kub no, thiab tom qab ntawd quenching thiab txias hauv huab cua.
Annealing: cua sov mus rau 750-800 degree, nyob ntawm qhov kub no rau 1-3h, nyob rau hauv qhov cub kom txias.
