d2 steel tiaj tus bar
Qib sib npaug: DIN 1.2379 / JIS SKD11 / GB Cr12Mo1V1.
Hardness xaiv 60-65HRC.
Cr12MOV D2 1.2379 SKD11Alloy Tool txias ua hauj lwm pwm steel
AISI d2 steel yog cov cuab yeej hlau uas muaj cov pa roj carbon ntau thiab siab chromium. AISI d2 steel muaj cov ntsiab lus carbon siab tab sis tsis muaj zog tiv thaiv lub siab thiab ua rau deformation. Vim tias hom hlau no muaj cov pa roj carbon ntau, nws yog qhov zoo tshaj plaws kom tsis txhob ua kom sov yog tias nws tsis xav tau tiag tiag, vim nws yuav cuam tshuam rau nws tus kheej kev ua haujlwm. Qhov kom zoo dua ntawm d2 steel tiaj tus bar yog tias nws muaj lub neej ntev kev pab cuam thiab hnav-tiv taus, yog li d2 steel tiaj tiaj bar yog tsim los ua stamping pwm rau kho vajtse. Tom qab kev kho mob txias, nws tseem tuaj yeem ua rau hauv cov ntawv hlau tsis muaj steel, yog li d2 cuab yeej steel muaj ntau yam kev siv.

D2 Forged Tool Steel tiaj tiaj Bar daim ntaub ntawv
d2 steel tiaj tiaj bar tuaj yeem siv los tsim ua haujlwm txias tuag steels nrog loj hla ntu, cov duab nyuaj, muaj kev cuam tshuam siab, thiab siab hnav tsis kam, xws li silicon steel ntawv stamping tuag, txias txiav txiab, ntug txiav tuag, thiab lwm yam. Nws kuj tseem tsim nyog rau kev tsim cov pwm nrog cov kev xav tau hardenability siab thiab cov cuab yeej uas yuav tsum tau muaj zog toughness thiab lub sij hawm ntev tuav, xws li tsim conical forming log, txias extrusion pwm, xuas nrig ntaus txiab, thiab lwm yam.
D2 steel muaj qhov ua tau zoo hauv qab no:
1. d2 cuab yeej hlau yog nplua nuj nyob rau hauv superhard alloy carbides, yog li nws muaj zoo hnav tsis kam.
2. Tom qab kev kho cua sov, d2 steel tiaj tiaj bar muaj qhov deformation me me.
3. Nws muaj lub zog hardenability, hardenability, thiab hnav tsis kam.
4. Zoo corrosion kuj tom qab quenching thiab polishing.
