quenching thiab tempering txheej txheem ntawm 316L stainless hlau sawb

quenching thiab tempering yog cov txheej txheem kho cua sov siv los txhim kho cov khoom siv hluav taws xob, suav nrog cov hlau tsis zoo li 316L. Cov txheej txheem no feem ntau yog siv los txhim kho hardness, lub zog, thiab toughness thaum tswj corrosion kuj. Nov yog li cas cov txheej txheem quenching thiab tempering tuaj yeem siv rau 316L stainless hlau sawb:

1. Annealing (Yeem): Ua ntej quenching thiab tempering, koj tuaj yeem xaiv anneal lub 316L stainless hlau sawb los txo cov kev ntxhov siab sab hauv thiab ua kom cov khoom zoo ib yam. Annealing muaj cua sov cov hlau mus rau qhov kub thiab txias (feem ntau nyob ib ncig ntawm 1900 ° F lossis 1040 ° C) thiab tom qab ntawd txias nws maj mam hauv kev tswj hwm.
2. Quenching: Kub lub 316L stainless hlau sawb rau nws austenitic kub, feem ntau nyob ib ncig ntawm 1850-2050 ° F (1010-1120 ° C) nyob ntawm seb muaj pes tsawg leeg.
   Tuav cov hlau ntawm qhov kub no rau lub sijhawm txaus los xyuas kom muaj cua sov zoo ib yam.
   Quench cov hlau sai sai los ntawm immersing nws nyob rau hauv ib tug quenching nruab nrab, feem ntau yog roj, dej, los yog ib tug polymer tov. Qhov kev xaiv ntawm quenching nruab nrab yog nyob ntawm qhov xav tau cov khoom thiab lub thickness ntawm cov sawb.
   quenching sai txias cov hlau, ua rau nws hloov los ntawm austenite mus rau ib tug nyuaj, ntau nkig theem, feem ntau martensite.
3. Tempering: Tom qab quenching, cov hlau yuav nyuaj heev tab sis nkig. Txhawm rau txhim kho toughness thiab txo brittleness, cov hlau yog tempered.
   Lub tempering kub yog qhov tseem ceeb thiab feem ntau nyob rau hauv thaj tsam ntawm 300-1100 ° F (150-590 ° C), nyob ntawm seb cov khoom xav tau. Qhov ntsuas kub yog nyob ntawm daim ntawv thov tshwj xeeb.
   Tuav cov hlau ntawm qhov kub thiab txias rau qee lub sijhawm, uas yuav txawv raws li qhov xav tau.
   Cov txheej txheem tempering txo cov hardness ntawm cov hlau thaum txhim kho nws cov toughness thiab ductility. Qhov siab dua qhov kub thiab txias, qhov softer thiab ductile steel yuav dhau los ua.
4. Txias: Tom qab tempering, tso cai rau 316L stainless hlau sawb kom txias ib txwm nyob hauv huab cua lossis ntawm tus nqi tswj mus rau chav sov.
5. Kev Ntsuas thiab Kev Tswj Xyuas Zoo: Nws yog ib qho tseem ceeb uas yuav tsum tau ua cov kev ntsuam xyuas kev siv tshuab thiab hlau rau ntawm qhov quenched thiab tempered sawb kom ntseeg tau tias nws ua tau raws li qhov xav tau tshwj xeeb thiab cov khoom. Cov kev ntsuam xyuas no tuaj yeem suav nrog kev sim hardness, ntsuas tensile, kuaj qhov cuam tshuam, thiab ntsuas microstructure. Qhov tshwj xeeb quenching thiab tempering tsis, xws li qhov kub thiab txias, yuav tsum tau txiav txim siab raws li cov khoom xav tau rau daim ntawv thov thiab tej zaum yuav xav tau kev sim thiab kev sim. Kev tswj kom zoo ntawm cov cua sov, tuav, quenching, thiab tempering txheej txheem yog qhov tseem ceeb rau kev ua tiav qhov xav tau sib npaug ntawm hardness, lub zog, thiab toughness thaum tswj corrosion kuj nyob rau hauv 316L stainless hlau. Tsis tas li ntawd, kev ceev faj txog kev nyab xeeb yuav tsum tau ua thaum ua haujlwm nrog cov txheej txheem kub thiab quenching nruab nrab.
