Brinell hardness kuaj
Brinell hardness test yog xam tus nqi hardness los ntawm kev siv lub siab ntawm cov hlau nplaum, siv lub carbide pob indenter, thiab ntsuas lub cheeb ntawm indentation. Qhov zoo ntawm Brinell hardness test yog qhov indentation loj, uas tuaj yeem cuam tshuam zoo rau tag nrho hardness ntawm cov khoom, thiab cov ntaub ntawv ruaj khov, qhov ntsuas qhov tseeb yog siab, thiab rov ua dua tau zoo. Qhov tsis zoo yog tias muaj qee qhov kev puas tsuaj rau saum npoo ntawm cov khoom siv, thiab lub sijhawm sim yog ntev.
Rockwell hardness test
Rockwell hardness test siv lub pob zeb diamond lossis steel pob indenter los ntsuas qhov tob ntawm qhov indentation los xam cov nqi hardness. Qhov zoo ntawm Rockwell hardness test yog qhov ntsuas ceev ceev thiab ua haujlwm yooj yim. Qhov tsis zoo yog qhov roughness ntawm cov khoom saum npoo yuav tsum siab, thiab qhov indentation yog me me, uas yuav tsis cuam tshuam tag nrho cov hardness ntawm cov khoom.
Vickers hardness xeem
Vickers hardness test siv lub tetrahedral pob zeb diamond indenter li niaj zaus los ntsuas qhov ntev ntawm kab pheeb ces kaum ntawm qhov indentation los xam cov nqi hardness. Qhov kom zoo dua ntawm Vickers hardness test yog tias qhov ntsuas qhov tseeb yog siab thiab nws tuaj yeem cuam tshuam zoo dua qhov microscopic hardness ntawm cov khoom. Qhov tsis zoo yog tias cov txheej txheem xeem yog qhov nyuaj thiab qhov roughness thiab flatness ntawm cov khoom nto yuav tsum siab.
Daim ntawv thov tshwj xeeb scenarios thiab cov qauv
Hauv kev lag luam roj av thiab tshuaj lom neeg, Brinell hardness test yog dav siv vim nws cov ntaub ntawv ruaj khov, ntsuas qhov tseeb thiab rov ua tau zoo. Rau Brinell hardness ntsuas ntawm nickel-raws li alloy yeeb nkab sib txuas welds, nws raug nquahu kom siv HBW10/300 ntsuas ntsuas.
GNEE yog ib lub tuam txhab muaj nplooj siab rau kev tshawb fawb thiab kev tsim kho thiab tsim cov precision stainless hlau ci raj, huv si kav (BA, EP) thiab tshwj xeeb alloy yeeb nkab series khoom. Nws tuaj yeem muab cov raj hlau precision nrog ntau yam ntaub ntawv thiab ntau thiab tsawg xws li austenite, duplex steel, npib tsib xee-raws li alloys raws li lub teb chaws tus qauv GB, ASTM, JIS, DIN, European qauv EN thiab lwm yam qauv.
