Kev quenching thiab tempering txheej txheem ntawm 316L stainless hlau strip

Kev quenching thiab tempering yog cov txheej txheem kho cua sov siv los txhim kho cov khoom siv kho tshuab ntawm cov ntaub ntawv, suav nrog cov hlau tsis xeb xws li 316L. Cov txheej txheem no feem ntau siv los txhim kho qhov nyuaj, lub zog, thiab kev tawv thaum tswj kev tiv thaiv corrosion. Nov yog li cas cov txheej txheem quenching thiab tempering tuaj yeem siv rau 316L stainless hlau strip:

1. Kev Ua Kub (Xaiv Tau): Ua ntej yuav kub thiab ua kom sov, koj xaiv tau los ua kom cov hlau tsis xeb 316L kub kom txo tau kev ntxhov siab sab hauv thiab xyuas kom meej tias cov khoom sib xws. Kev ua kub suav nrog kev ua kom cov hlau kub txog qhov kub tshwj xeeb (feem ntau nyob ib puag ncig 1900°F lossis 1040°C) thiab tom qab ntawd txias qeeb qeeb hauv txoj kev tswj hwm.
2. Kev Tua Kab: Ua kom sov lub hlau tsis xeb 316L rau nws qhov kub austenitic, feem ntau nyob ib puag ncig 1850-2050 ° F (1010-1120 ° C) nyob ntawm cov khoom xyaw tshwj xeeb.
   Tuav cov hlau ntawm qhov kub no kom txaus kom ntseeg tau tias muaj cua sov sib xws.
   Ua kom cov hlau kub sai sai los ntawm kev muab tso rau hauv cov khoom siv kub, feem ntau yog roj, dej, lossis cov kua polymer. Kev xaiv cov khoom siv kub nyob ntawm cov yam ntxwv xav tau thiab qhov tuab ntawm daim hlau.
   Kev quenching ua rau cov hlau txias sai, ua rau nws hloov pauv ntawm austenite mus rau theem nyuaj dua, tawg yooj yim dua, feem ntau yog martensite.
3. Kev Kho Mob Kub: Tom qab quenching, cov hlau yuav tawv heev tab sis brittle. Txhawm rau txhim kho toughness thiab txo brittleness, cov hlau yog tempered.
   Qhov kub ntawm kev ua kom sov yog qhov tseem ceeb heev thiab feem ntau yog nyob rau hauv qhov ntau ntawm 300-1100 ° F (150-590 ° C), nyob ntawm seb cov khoom xav tau. Qhov kub tseeb nyob ntawm daim ntawv thov tshwj xeeb.
   Tuav cov hlau ntawm qhov kub tempering rau ib lub sijhawm ntev, uas yuav txawv raws li cov khoom xav tau.
   Cov txheej txheem tempering txo qhov nyuaj ntawm cov hlau thaum txhim kho nws cov tawv thiab ductility. Qhov kub tempering siab dua, cov hlau yuav mos dua thiab ductile dua.
4. Txias: Tom qab tempering, cia lub 316L stainless hlau strip txias ntuj hauv huab cua lossis ntawm tus nqi tswj hwm rau chav tsev kub.
5. Kev Ntsuas thiab Kev Tswj Xyuas Zoo: Nws yog ib qho tseem ceeb uas yuav tsum ua qhov kev ntsuam xyuas tshuab thiab hlau ntawm daim hlau uas tau quenched thiab tempered kom ntseeg tau tias nws ua tau raws li cov lus qhia thiab cov khoom xav tau. Cov kev ntsuam xyuas no yuav suav nrog kev ntsuam xyuas qhov nyuaj, kev ntsuam xyuas tensile, kev ntsuam xyuas kev cuam tshuam, thiab kev tshuaj xyuas microstructure. Cov kev ntsuas tshwj xeeb quenching thiab tempering, xws li qhov kub thiab lub sijhawm, yuav tsum txiav txim siab raws li cov khoom xav tau rau daim ntawv thov thiab yuav xav tau kev sim thiab kev sim. Kev tswj hwm kom zoo ntawm cov txheej txheem cua sov, tuav, quenching, thiab tempering yog qhov tseem ceeb rau kev ua tiav qhov sib npaug ntawm qhov nyuaj, lub zog, thiab kev tawv thaum tswj kev tiv thaiv corrosion hauv 316L stainless hlau. Tsis tas li ntawd, kev ceev faj kev nyab xeeb yuav tsum tau ua thaum ua haujlwm nrog cov txheej txheem kub siab thiab cov khoom siv quenching.
