40Cr, 40 chromium Rockwell hardness test method

Tom qab quenching thiab tempering, chromium muaj cov khoom siv zoo heev thiab zoo hardenability, uas ua rau nws feem ntau siv rau hauv kev tsim cov high-strength fasteners, bearings, gears, thiab camshafts. Mechanical zog thiab hardness xeem yog heev tsim nyog rau quenched thiab tempered 40Cr.

40Cr hardness test feem ntau siv Rockwell hardness test method thiab Brinell hardness test method rau kev sim. Vim Rockwell hardness tester yog ceev thiab yooj yim rau siv, nws yog feem ntau nyiam los ntawm cov neeg muas zaub. Rau qhov me me lossis qhov xav tau siab dua, Vickers hardness tester kuj tseem siv tau.

Feem ntau, Rockwell hardness ntawm 40Cr tom qab quenching thiab tempering feem ntau yuav tsum nyob nruab nrab ntawm HRC32-36, kom nws muaj zog dua thiab qaug zog kuj.

Cov hauv qab no yog ob peb feem ntau siv Rockwell hardness testers rau siv:

1. Qhov hnyav-ntxiv hluav taws xob digital zaub Rockwell hardness tester: muaj tseeb, txhim khu kev qha, ruaj khov, thiab kev ntsuas siab; cov duab digital tuaj yeem nyeem ncaj qha rau Rockwell hardness tus nqi, cov qauv kev kho kom zoo, thiab lwm yam Rockwell nplai tuaj yeem xaiv tau. Nws txais kev siv hluav taws xob tsis siv neeg thauj khoom thiab thauj khoom siv tshuab kom tshem tawm tib neeg yuam kev. Lub tshuab spindle txais yuav cov qauv tsis muaj kev sib txhuam los txhim kho qhov tseeb ntawm qhov kev sim thawj zaug

2. Kov npo digital zaub Rockwell hardness tester: yim-nti kov npo ua haujlwm, yooj yim thiab yooj yim rau kev khiav lag luam interface; hluav taws xob loading xeem quab yuam, tsawg tsis ua hauj lwm tus nqi, kev ntsuam xyuas yog ntau dua, muaj peev xwm ntawm nws tus kheej khaws 500 teev cov ntaub ntawv, fais fab tuag yam tsis muaj ntaub ntawv poob, raws li ISO, ASTM E18 thiab lwm yam qauv.

3. Tsis siv neeg Rockwell hardness tester tag nrho: hluav taws xob loading tester yog siv los txhim kho tus nqi quab yuam, ib-nias kom tiav tag nrho cov txheej txheem hardness, yooj yim thiab muaj txiaj ntsig; super loj xeem platform, tsim nyog rau hardness nrhiav kom tau ntawm loj-scale ua hauj lwm; nruab nrog lub joystick kom ceev ceev servo lub cev muaj zog los kho qhov chaw sim; Cov ntaub ntawv tuaj yeem xa mus rau lub computer ntawm RS232, Bluetooth lossis USB.
