Kev Xa Khoom
EAF plus LF plus VD plus (ESR), Forged, Unmachined los yog Machined nto, UT 100 feem pua Ntau
Peb muab ob yam xwm txheej li
Annealed: Hardness Tsawg dua los yog sib npaug rau 235HB
Q ntxiv T: Hardness 33-38HRC lossis raws li kev cai
Yam ntxwv
Martensite stainless hlau, nrog zoo machincability thiab zoo heev corrosion kuj, polishability, thiab siab zog thiab hnav tsis kam tom qab kev kho cua sov.
Daim ntawv thov
Nws kuj yog siv dav rau kev ua cov pwm yas thiab cov yas pwm pob tshab uas yuav tsum muaj kev thauj khoom siab, hnav tsis kam, thiab ua haujlwm raws li qhov kev txiav txim ntawm corroding nruab nrab.
Forging Technique
Kev kho cua sov
| Kub kub | Pib Forging Kub | Ua kom tiav Forging Kub | Txoj kev txias |
| Maj mam cua sov mus rau 800ºC, tom qab ntawd sai sai rau qhov kawg forging kub | 1160-1200ºC | >=850ºC | Tshauv coolinor xuab zeb txias, nrog rau lub sijhawm annealing |
Annealing
840 rau 870 degree
Kev tswj kom txias qeeb hauv qhov cub ntawm tus nqi ntawm 10 txog 20 degree / hr mus rau kwv yees li. 600 degree, ntxiv txias hauv huab cua. Hardness tom qab annealing: max. 229 HB.
Kev ntxhov siab
Kwv yees li. 650 degree
Ua kom txias qeeb hauv qhov cub; npaj los txo kev ntxhov siab los ntawm kev siv tshuab dav dav, lossis hauv cov duab nyuaj. Tom qab ua cua sov, tuav hauv nruab nrab cua rau 1 - 2 teev.
Hardening
1000 txog 1050 degree / Roj, cua
Tuav lub sij hawm tom qab kub sib npaug: 15 mus rau 30 feeb.
Tau txais hardness: 53-56 HRC
Tempering
100 txog 200 degree (212 txog 392 degree F)
Ua cua sov qeeb rau qhov kub thiab txias tam sim ntawd tom qab hardening / sij hawm hauv qhov cub
1 teev rau txhua 20 hli ntawm workpiece thickness tab sis tsawg kawg yog 2 teev / txias hauv huab cua.
Rau qhov nruab nrab hardness cov nuj nqis yuav tsum tau thov mus rau daim ntawv tempering.
Peb tuaj yeem muab tau li cas?
Peb muab ntau yam ntawm cov khoom steel nyob rau hauv ib tug ntau yam ntawm qhov ntev thiab kev tua, acc.to lub thoob ntiaj teb specifications los yog customerized.
Machining thiab kev kho cua sov yog muaj.
Tsis tas li, peb qhia koj hauv kev xaiv cov ntaub ntawv zoo.
