4340 Steel Bar UT Test:
Peb 4340 alloy steel tiaj tus tuav tau raug kuaj xyuas ultrasonic (UT) kom ntseeg tau tias lub suab sab hauv thiab cov qauv tsis raug. Txoj kev kuaj tsis muaj kev puas tsuaj no tshawb pom cov kev cuam tshuam sab hauv xws li cov kab nrib pleb, voids, thiab kev suav nrog uas tsis pom ntawm qhov muag liab qab. Kev tshuaj xyuas UT yog ua raws li cov qauv kev lag luam, ua kom txhua lub bar ua tau raws li qhov xav tau ntawm kev ua haujlwm siab rau aerospace, tsheb, thiab kev siv hluav taws xob hnyav. Txhim khu kev ruaj ntseg zoo guarantees txhim khu kev qaug zog tiv thaiv, kev tsim kev ncaj ncees, thiab cov neeg siv kev ntseeg siab.
4340 Alloy Bar PMI Test:
Txhawm rau kom ntseeg tau cov khoom siv taug qab thiab ua raws li cov neeg siv khoom tshwj xeeb, PMI (Positive Material Identification) yog ua los ntawm AISI 4340 Alloy Steel Flat Bars siv cov spectrometers lossis X-ray fluorescence (XRF) analyzers. Txoj kev kuaj tsis muaj kev puas tsuaj no txheeb xyuas cov tshuaj muaj pes tsawg leeg ntawm txhua tus naj npawb cua sov, kom ntseeg tau tias nws ua tau raws li qhov xav tau ntawm cov khoom siv alloying xws li Ni, Cr, thiab Mo.
4340 Bar Hardness Test:
Txhawm rau kom paub meej qhov kev kho cua sov thiab txheeb xyuas qhov kev ua tau zoo ntawm cov khoom siv, kev ntsuas hardness yog ua los ntawm AISI 4340 Alloy Steel Flat Bars siv Rockwell lossis Brinell txoj kev. Rau quenched thiab tempered tuav, qhov nyuaj hardness yog 24 txog 38 HRC. Hardness qhov tseem ceeb tau sau tseg ntawm ntau qhov chaw thoob plaws qhov chaw thiab ntu ntu kom ntseeg tau tias muaj kev sib haum xeeb. Cov txiaj ntsig tau pab kom paub meej tias cov hlau tsim nyog rau cov ntawv thov uas muaj kev ntxhov siab thiab cuam tshuam.
