Din 1.2888 Pwm Steel Sib npaug
Hom: Round bar
Lub sij hawm xa tuaj: Annealed dub nto / Tig ci nto / Q ntxiv T
Khoom Description
1.2888 pwm steel sib haum rau cov khoom siv hauv tsev 20Cr9W6Mo2Co10, yog qhov kev xaiv zoo rau extrusion magnesium khoom pwm. 1.2888 steel yog ib hom tshiab ntawm kub kub resistant high speed steel uas tsim los ntawm kev siv cov cuab yeej siv siab tshaj steelmaking, uas muaj cov yam ntxwv ntawm lub zog siab, kub tsis kam thiab hnav tsis kam. 1.2888 pwm hlau yog tsuas yog siv rau hauv lub taub hau lub taub hau, lub cev lub cev, lub raj dej thiab lwm yam ntawm txhuas tuag-casting, magnesium alloy, tooj liab tuag-casting pwm.
1.2888 Steel Kev kho cua sov
Quenching kub: 1100-1150 degree
Tempering kub: 600-750 degree
Tempering hardening tus nqi / MPa
500 degree -55
600 degree -54
650 degree - 53 (nto hardness tom qab deg hardening)
1.2888 Steel Yam ntxwv:
Nws yog ib hom huab cua quenched thiab hardened kub ua hauj lwm tuag steel, zoo ib yam li lub tebchaws United States H13 tuag steel. Nws qhov kev ua tau zoo thiab kev siv yog qhov zoo ib yam li ntawm 4Cr5MoSiV steel, tab sis vim nws cov ntsiab lus vanadium siab dua, nws qhov nruab nrab kub (600 degree) kev ua tau zoo dua li ntawm 4Cr5MoSiV steel, uas yog cov neeg sawv cev qib steel dav siv hauv kev ua haujlwm kub tuag. hlau.
