Qhov Hardness ntawm ASTM A240 Hom 316 yog dab tsi?
ASTM A240 Hom 316yog ib qib nrov ntawm stainless hlau uas feem ntau siv rau hauv daim ntawv thov uas yuav tsum tau zoo heev corrosion kuj thiab siab zog. Qee qhov kev siv ntau yam ntawmASTM A240 UNS S31600 phajsuav nrog cov khoom siv hauv hiav txwv, tshuaj, khoom siv tshuaj lom neeg, khoom siv ua zaub mov, thiab cov khoom siv kho mob. Ib qho ntawm cov khoom tseem ceeb ntawm cov khoom siv no yog nws cov hardness, uas ua lub luag haujlwm tseem ceeb hauv nws cov kev ua tau zoo hauv kev siv sib txawv.
Hardness txhais tau tias yog lub peev xwm ntawm cov khoom los tiv thaiv indentation lossis nkag mus. Nws yog ib qho tseem ceeb ntawm cov cuab yeej cuab tam uas feem ntau siv los ua lub zog thiab ua haujlwm ntev ntawm cov khoom siv. Nyob rau hauv cov ntaub ntawv ntawm ASTM A240 Qib 316, qhov nyuaj tuaj yeem ntsuas tau siv ntau txoj hauv kev, suav nrog Rockwell hardness, Brinell hardness, thiab Vickers hardness.
ASTM A240 TP316 Daim Ntawv Rockwell Hardness
Rockwell hardness test yog ib txoj hauv kev zoo los ntsuas qhov hardness ntawm cov khoom siv hlau. Nws suav nrog kev siv lub pob zeb diamond lub khob hliav qab lossis lub pob zeb tawv tawv ua ib qho indenter thiab lub nra uas siv rau cov khoom siv. Qhov tob ntawm qhov nkag ntawm qhov indenter yog ntsuas, thiab tus nqi hardness yog xam raws li Rockwell nplai. Rockwell hardness ntawm1.4401 AISI 316 khoomtuaj yeem nyob ntawm 79 txog 95 nyob ntawm seb qhov xwm txheej ntawm cov khoom siv.
ASME SA 240 Hom 316 Sawb Brinell Hardness
Brinell hardness test yog lwm txoj hauv kev los ntsuas qhov hardness ntawm cov khoom siv hlau. Nws suav nrog kev siv lub pob hlau tawv tawv ua ib qho indenter thiab lub nra uas siv rau cov khoom siv. Lub cheeb ntawm qhov indentation yog ntsuas, thiab tus nqi hardness yog xam raws li Brinell nplai. Brinell hardness ntawm1.4436 AISI 316tuaj yeem nyob ntawm 149 txog 217 nyob ntawm qhov tshwj xeeb ntawm cov khoom siv.
ASTM A240 UNS S31600 Phaj Vickers Hardness
Vickers hardness test yog ib txoj hauv kev microindentation uas feem ntau siv los ntsuas qhov hardness ntawm nyias zaj duab xis thiab txheej. Nws suav nrog kev siv lub pob zeb diamond indenter thiab lub nra uas siv rau cov khoom siv. Qhov loj ntawm qhov indentation yog ntsuas, thiab tus nqi hardness yog xam raws li Vickers nplai. Vickers hardness ntawmASME SA240 TP 316tuaj yeem nyob ntawm 200 mus rau 240 nyob ntawm qhov tshwj xeeb ntawm cov khoom siv.
Hauv kev xaus, hardness ntawm ASTM A240 Hom 316yog ib qho tseem ceeb ntawm cov cuab yeej cuab tam uas ua lub luag haujlwm tseem ceeb hauv nws cov kev ua tau zoo hauv kev siv sib txawv. Lub hardness tuaj yeem ntsuas tau siv ntau txoj hauv kev, suav nrog Rockwell hardness, Brinell hardness, thiab Vickers hardness. Qhov tshwj xeeb hardness qhov tseem ceeb ntawm ASTM A240 316 nyob ntawm seb qhov tshwj xeeb ntawm cov khoom thiab cov qauv siv los ntsuas nws.
