Cov yam ntxwv tseem ceeb rau riam ua kom zoo
1. Unmatched Edge Retention & Wear Resistance Carbide- Cov qauv nplua nuj:
High chromium thiab carbon form hard (M7C3) carbides, tsim cov hniav nto uas tiv thaiv micro- abrasion los ntawm rov txiav, txiav, thiab chopping. Ntev-Ntev ntse ntse: tuav lub chais ntug los ntawm ntau txhiab tus siv, txo re-ntxhiab zaus rau cov kws ua zaub mov, cov neeg yos hav zoov, thiab cov neeg siv cov cuab yeej siv.
2. Precision Heat Treatment Control Vacuum Hardening:
Hardens rau 60–62 HRC nrog tsawg distortion (tsawg dua los yog sib npaug rau 0.05mm / m), ua kom cov hniav zoo ib yam geometry rau precision cov cuab yeej xws li scalpels los yog engraving riam. Tempering Flexibility: Tau tempered ntawm 150–500℃los kho toughness-hardness balance: Low-tempering (150–200 degree): siab tshaj hardness rau fine{10}}edged riam. Siab-tempering (400–500 degree): Txhim kho toughness rau hnyav{15}} cov hniav (xws li, machetes, axes).
3. Ntau yam Fabrication rau Hniav Manufacturers Annealed Workability:
Lub xeev mos (tsawg dua lossis sib npaug li 250 HB) tso cai yooj yim machining, drilling, thiab profiling -zoo tagnrho rau kev txiav cov hniav dawb lossis cov riam phom nyuaj. Weldability: Ua ntej- cua sov (200–300 degree) ua rau TIG/MIG vuam rau kev kho hniav cov lus qhia los yog fabricating composite handles.
4. Kev Tiv Thaiv Corrosion & Nto Finish Chromium Advantage:
12% Cr cov ntsiab lus muab kev tiv thaiv zoo rau xeb thiab cov kua qaub me me dua li cov hlau, haum rau cov riam hauv chav ua noj thiab cov cuab yeej sab nraum zoov. Kev Kho Mob Nto: Polished (Ra Tsawg dua lossis sib npaug ntawm 0.4μm): Daim iav tiav rau cov hniav zoo nkauj lossis siab -kawg cutlery. Phom Blasted (Sa 2.5): Textured nto rau txhim kho tuav thaum tuav kev sib raug zoo.

FAQ
Q: Puas yog D2 yog qhov kev xaiv zoo rau rab riam uas yuav pom kev siv zog hauv thaj teb?
A: Yog, yog tias koj lees txais qis dua toughness hauv kev pauv rau ntug tuav. D2 ntawm HRC 58-62 tiv taus abrasive hnav txog peb zaug zoo dua li 1095. Rau cov tawv nqaij, txiav, thiab txiav cov duab los yog hlua, nws nyob twj ywm ntev dua. Tab sis rau chopping los yog batoning, ib tug tougher hlau zoo li 3V los yog A2 yog muaj kev ruaj ntseg dua. D2 tuaj yeem nti yog tias ntug nyias dhau los yog qhov tawv tawv raug thawb siab dhau.
Q: Puas yog D2 xeb yog tias kuv siv rau chav ua noj lossis riam nuv ntses?
A: Nws muaj 11-13% chromium, yog li nws stains tsawg dua cov pa roj carbon monoxide, tab sis nws tsis yog stainless. Cov dej ntsev thiab cov zaub mov acidic yuav tawm cov cim yog tias koj tsis qhuav thiab roj cov hniav. Rau riam chav ua noj uas tau wiped ntau zaus, nws yog tswj tau. Rau lub nkoj riam lossis rab riam dhia dej, xaiv 440C, 14C28N, lossis cov hniav sib tsoo.
Q: Kuv yuav ua li cas kom sov D2 hniav kom tau qhov zoo tshaj plaws sib npaug ntawm hardness thiab toughness?
A: Austenitize, quench, ces temper. Rau qhov siab tshaj plaws tuav, kub siab ntawm 150-200℃thiab tsom rau HRC 60-62. Rau cov hniav loj dua uas pom qhov cuam tshuam, kub siab ntawm 400-500℃thiab txais HRC 58-60. Cov hlau yog huab cua- hardening, yog li lub tshuab nqus tsev vacuum los yog cov cua tswj tau muab qhov tsis sib xws tsawg tshaj plaws. Phaj thickness tseem ceeb heev. Nyias cov khoom cua sov thiab quenches sai dua, yog li saib koj lub sijhawm so.
Q: Kuv puas tuaj yeem yuav D2 hauv pre- lub xeev hardened thiab tsuas yog zom cov bevel?
A: Yog. Peb npaj ua ntej- hardened D2 ntawm 30–35 HRC. Koj tuaj yeem ua qhov profile, laum, thiab ntog nws yam tsis muaj kev kho cua sov tag nrho. Tab sis qhov hardness yog rau shaping, tsis yog rau qhov kawg ntug kev ua tau zoo. Thaum cov hniav geometry ze, koj tseem yuav tsum tau ua kom tawv thiab npau taws rau 58-62 HRC ua ntej sharpening. Yog tias koj xav hla kev kho cua sov nkaus xwb, peb tuaj yeem muab cov phaj siab tawv thiab tempered ntawm koj lub hom phiaj hardness.
Q: Koj puas muab ua ntej- rab riam hauv av hauv D2, lossis tsuas yog phaj tiaj tus?
A: Peb tuaj yeem txiav thiab ua ntej- txhuam qhov khoob rau koj qhov profile, suav nrog kev poob -point, tanto, thiab sheepsfoot duab. Kev kam rau siab yog li ± 0.02mm ntawm qhov profile. Cov bevels tuaj yeem sab laug nrog kev sib tsoo nyiaj kom koj ua tiav ntawm ntug koj tus kheej. Qhov no txuag ntau lub sijhawm sib tsoo ntxhib, tshwj xeeb tshaj yog ntawm cov khoom tuab. Xa DXF lossis kos duab nrog lub thickness, ntev, thiab hardness xeev.
Q: Dab tsi thickness D2 phaj kuv yuav tsum tau txiav txim rau ib tug neeg yos hav zoov los yog tactical riam?
A: Rau tag nrho - tus neeg yos hav zoov, 3-4mm yog ntau. Rau ib rab riam los yog ciaj sia taus, 4-6mm muab lub zog ntau dua rau prying thiab chopping. Rau chav ua noj nyias nyias los yog rab riam, 1.5-2.5mm ua haujlwm yog tias koj khaws cov hniav geometry ruaj khov thaum lub sij hawm hardening. Peb npaj cov ntawv txias txias los ntawm 1.0-2.5mm thiab kub dov phaj los ntawm 2.55-12mm, yog li koj tuaj yeem phim cov tuab rau hom hniav yam tsis muaj tshaj - xaj.
