Hardness ntawm cov khoom sib txawv ntawm steel pob

Cov npas hlau yog cov khoom tseem ceeb ntawm ntau yam kev lag luam, suav nrog kev siv cov kabmob, sib tsoo xov xwm, thiab deflectors. Cov pob hlau no tuaj yeem tuaj hauv ntau yam ntaub ntawv, txhua qhov sib txawv ntawm hardness thiab durability. Nkag siab txog qhov nyuaj thiab kev sim rau cov pob hlau no yog qhov tseem ceeb rau kev txiav txim siab tsim nyog rau cov ntawv thov tshwj xeeb.

Cov ntaub ntawv xws li stainless hlau, chrome steel, thiab carbon steel feem ntau siv los ua cov pob hlau. Txhua yam ntawm cov ntaub ntawv no muaj kev sib xyaw ua ke ntawm cov khoom uas cuam tshuam qhov hardness ntawm cov khoom kawg. Cov pa roj carbon steel cov khoom siv tau ruaj khov, tab sis lawv feem ntau siv rau hauv cov ntawv thov qis vim lawv qhov hardness tsawg. Chrome steel npas muaj cov khoom zoo los tiv thaiv kev sib txhuam, ua rau lawv zoo tagnrho rau kev siv kabmob. Stainless hlau npas yog corrosion-resistant thiab muaj qib siab hardness, ua rau lawv haum rau huab cua kub daim ntaub ntawv.

Txawm li cas los xij, lub hardness ntawm steel pob tsis tsuas yog txiav txim siab los ntawm cov khoom siv. Cov txheej txheem tsim khoom kuj ua lub luag haujlwm tseem ceeb hauv qhov kawg hardness. Kev kho cua sov thiab kev ua haujlwm txias yog ob txoj hauv kev siv los txhim kho hardness. Kev kho cua sov yuav tsum ua kom sov cov hlau, tom qab ntawd txias nws hauv cov xwm txheej tshwj xeeb los tsim cov hardness tshwj xeeb. Kev ua haujlwm txias yog ua rau cov hlau rau cov yas deformation ntawm qhov kub thiab txias kom muaj zog thiab hardness.

Kev ntsuas qhov nyuaj ntawm cov pob hlau yuav tsum muaj ntau txoj hauv kev, suav nrog Brinell hardness, Rockwell hardness, thiab Vickers hardness. Brinell hardness ntsuas qhov tsis kam ntawm steel rau indentation. Txoj kev no suav nrog muab lub pob-zoo li tus indenter rau saum npoo ntawm cov hlau thiab ntsuas qhov tshwm sim indent. Rockwell hardness, ntawm qhov tod tes, yuav tsum nias lub pob lossis pob zeb diamond-puab indenter rau saum npoo ntawm cov hlau thiab ntsuas qhov tob ntawm indentation. Vickers hardness ntsuas qhov tsis kam ntawm cov hlau rau indentation siv lub pob zeb diamond-shaped indenter thiab ntsuas los ntawm qhov loj ntawm qhov tshwm sim.

Hauv kev xaus, cov pob steel tuaj hauv cov khoom sib txawv thiab qib hardness, txhua tus nrog lawv cov khoom tshwj xeeb. Kev nkag siab txog cov khoom no thiab cov qauv kev sim yog qhov tseem ceeb rau kev txiav txim siab lub pob steel kom raug siv rau hauv ib daim ntawv thov. Nrog rau lub pob hlau zoo, cov txheej txheem kev lag luam tuaj yeem ua haujlwm tau zoo dua, thiab cov khoom siv tuaj yeem ua haujlwm ntev, ua rau muaj kev tsim khoom ntau ntxiv thiab txuag nqi.
