Silicon ua tus deoxidizer thaum lub sij hawm ua cov hlau thiab tseem pab txhawb rau tag nrho lub zog thiab hardness ntawm cov khoom. Kev ua tib zoo sib piv ntawm cov ntsiab lus no ua kom ntseeg tau tias SA 516 Gr.60 steel phaj muaj cov tshuaj lom neeg xav tau rau kev ua haujlwm zoo hauv kev ua haujlwm sib txawv.
Cov khoom siv kho tshuab ntawm SA 516 Gr.60 steel phaj yog qhov tseem ceeb heev thiab raug kuaj nruj thiab ntsuas. Lub zog tensile ntsuas cov khoom lub peev xwm los tiv thaiv stretching rog thiab qhia nws tag nrho lub zog. Lub zog yield marks lub ntsiab lus ntawm cov hlau pib mus rau yas deformation, muab cov ntaub ntawv tseem ceeb rau kev tsim thiab engineering lub hom phiaj. Lub zog tawm los siab ua kom lub phaj tuaj yeem tiv taus cov khoom thauj thiab kev ntxhov siab nws yuav ntsib hauv kev pabcuam.
Elongation thiab txo nyob rau hauv cheeb tsam yog cov cim ntawm cov hlau ductility, qhia nws lub peev xwm deform yam tsis muaj pob txha. Zoo ductility yog qhov tseem ceeb rau kev nqus lub zog thaum lub sijhawm thauj khoom thiab tso cai rau kev tsim thiab tsim cov txheej txheem yam tsis muaj kev tawg. Lub hardness ntawm steel phaj kuj tseem tswj kom tau raws li cov kev cai tshwj xeeb ntawm daim ntawv thov, kom ntseeg tau tias tsim nyog hnav tsis kam thiab machinability.
Kev cuam tshuam tsis zoo, raws li kev txiav txim siab los ntawm kev ntsuas kev cuam tshuam xws li Charpy lossis Izod kev sim, yog qhov tseem ceeb, tshwj xeeb tshaj yog nyob rau hauv ib puag ncig uas cov hlau yuav raug cuam tshuam los ntawm kev thauj khoom hnyav lossis kub qis. Lub zog qaug zog yog lwm yam khoom tseem ceeb, tshwj xeeb tshaj yog rau cov khoom raug rau kev thauj khoom cyclic dhau lub sijhawm ntev.
Kev sib xyaw ua ke ntawm cov tshuaj muaj txiaj ntsig zoo thiab cov khoom siv zoo heev ntawm SA 516 Gr.60 steel phaj ua rau nws yog qhov kev xaiv zoo tshaj plaws rau kev siv xws li cov hlab ntsha siab, cov tso tsheb hlau luam, boilers, thiab cov khoom siv hauv cov roj thiab roj, tshuaj. , thiab fais fab kev lag luam. Cov qib sib txawv thiab kev hloov pauv hauv SA 516 series tuaj yeem muab cov khoom sib txawv me ntsis thiab cov khoom kom tau raws li cov kev xav tau tshwj xeeb ntawm ntau hom kev siv thiab chaw ua haujlwm.
Thaum lub sij hawm tsim thiab fabrication txheej txheem, nruj zoo tswj kev ntsuas yog siv los xyuas kom meej tias cov hlau daim hlau ua raws li cov txheej txheem tshuaj muaj pes tsawg leeg thiab cov cuab yeej cuab tam. Kev tshuaj xyuas tshuaj yog ua los xyuas kom meej qhov muaj pes tsawg leeg, thaum kev ntsuam xyuas tshuab tau ua los ntsuas lub zog tensile, lub zog tawm los, ductility, hardness, thiab cuam tshuam tsis kam. Cov kev kuaj tsis muaj kev puas tsuaj xws li kev tshuaj xyuas ultrasonic thiab kev kuaj cov hlau nplaum yog ua haujlwm los kuaj xyuas cov teeb meem sab hauv lossis qhov chaw uas tuaj yeem cuam tshuam qhov kev ncaj ncees thiab kev ua haujlwm ntawm cov hlau phaj.
Hauv cov ntsiab lus, SA 516 Gr.60 steel phaj cov tshuaj muaj pes tsawg leeg thiab cov khoom siv kho tshuab tau ua tib zoo tsim thiab tswj kom muab cov khoom siv txhim khu kev qha thiab kev ua haujlwm siab rau ntau yam kev lag luam. Kev nce qib txuas ntxiv hauv cov ntaub ntawv kev tshawb fawb thiab kev tsim thev naus laus zis ntxiv txhim kho qhov zoo thiab muaj peev xwm ntawm cov hlau no, ua kom nws qhov tseem ceeb thiab kev ntseeg siab ntxiv hauv kev ua kom tau raws li cov kev xav tau ntawm kev tsim kho niaj hnub thiab kev tsim kho.
