Qhov sib txawv ntawmHRB thiab HRC Hardness Rau 304 Stainless Hlau Bar
Nyob rau hauv hardness ntsuas ntawm 304 stainless hlau tuav, HRB thiab HRC yog ob lub thoob pob zeb hardness nplai. Cov tub ntxhais sib txawv ntawm lawv cov lus dag nyob rau hauv hom indenter thiab thauj khoom siv thaum kuaj:
🔹HRB:Siv ib 1 / 16- nti hlau ua cov khoom siv qub li Annaled li Annealed li 304 stainless, uas feem ntau muaj qhov nyuaj ntawm {}} hrb.
🔹HRC:Siv lub pob zeb diamond iav indenter thiab 150 KGF thauj, ua kom haum rau cov khoom harder. 304 Stainless hlau, feem ntau yog qhov nyuaj ntawm tsawg dua 20 hrc thiab feem ntau tsis siv rau kev sim HRC tshwj tsis yog tias nws tau mob siab rau kev mob siab tshwj xeeb.
304 stainless hlau bar hardness conversion rooj Conversion rooj
| HRB (Rockwell B Nplai) | HRC (Rockwell C Nplai) | Khoom Siv Khoom Mob |
|---|---|---|
| 85-90 | <15 | Tag nrho anealed (lub xeev muag muag) |
| 90-95 | 15-20 | Kev ua haujlwm me me-tawv (lub xeev txias) |
| >95 | >20 (tsis tshua muaj) | Ua haujlwm hnyav-tawv lossis kho tshwj xeeb |
🔹Muaj nplai:
304 Stainless hlau, ua ib qho kev siv hlau tsis xeb, muaj qhov nyuaj qis hauv nws lub xeev annealed ({}} hrb). Nws yog feem ntau sim siv HRB nplai (hlau pob indenter nrog 100 kgf thauj).
Lub HRC nplai (Pob Zeb Diam ywm lub khob txhais lus nrog 150 KGF thauj khoom) yog ib txwm tsis siv rau cov khoom siv nyuaj (zoo li nws feem ntau muaj tsawg dua 20 teev.
🔹Khoom siv:
Tag nrho Annealed 304 stainless hlau (lub xeev muag muag) yuav muaj hardness nyob rau hauv thaj tsam ntawm {1}} hrb.
Ua haujlwm me-tawv-hardened 304 stainless hlau (zoo li txias-kos) yuav qhia hardness nruab nrab ntawm {}} hrb.
Ua haujlwm hnyav lossis kho tshwj xeeb lossis kho tshwj xeeb 304 stainless hlau tej zaum yuav qhia tau hardness saum 95 hrc, txawm tias HRC qhov tseem ceeb rau cov ntaub ntawv zoo li no tseem tsawg.
🔹Kev Ntseeg Kev Ntseeg:
Tsis muaj nrujTawm Hloov Hloov Cov Lusntawm HRB thiab HRC NPLAI. Cov ntaub ntawv nyob rau hauv lub rooj yog ua raws li kev sim ua thiab yog txhais tau rau kev siv lub hom phiaj nkaus xwb.
Thaum kuaj, nws yog ib qho tseem ceeb kom xaiv cov nplai kom haum raws li cov khoom siv kom ntseeg tau tias tau txais txiaj ntsig.
🔹Cov nyhuv ntawm kev ua:
Txias duab kos los yog muab rhaub txias yuav ua rau lub hardness ntawm 304 stainless hlau (tsa tus nqi HRB), thiab nws yuav ua rau muaj txiaj ntsig me ntsis hauv HRC. Txawm li cas los xij, 304 stainless hlau tsis tuaj yeem ua rau muaj kev kho mob cua sov xws li kev ua kom qis dua li ntawm Martensitic Stainless hlau (zoo li 410 lossis 420).
