Alloy 304L Weldability
ASTM A213 UNS S30400 yeeb nkab muaj qhov zoo tshaj plaws weldability thiab machinability, thiab tuaj yeem raug rau ntau yam kev ua haujlwm thiab precision manufacturing raws li xav tau.AISI 304Ltuaj yeem welded los ntawm txoj kev zoo tib yam vim tias nws cov ntsiab lus carbon siab tshaj plaws yog 0.035%, uas tuaj yeem cuam tshuam cov nag lossis daus ntawm carbides thiab muaj kev vuam zoo. Rau phau ntawv arc vuam, rau 304 stainless hlau nrog thinner cross-sectional qhov ntev, austenitic 002 vuam pas nrig yuav siv tau, uas yuav tsis tsim intergranular corrosion nyiam.
SS 304L Yeeb Nkab Thaum tshav kub kub kho txheej txheem
Tshuaj kho kub ntawmDIN 1.4301 stainless hlauyog 1080-1100 degree , dej txias lossis cua txias. Qhov nruab nrab annealing kub ntawm kev ua haujlwm txias yog 850-970 degree, thiab dej txias yog ua tom qab qee lub sijhawm nyob. Cov qauv hlau tom qab kev daws teeb meem yog austenite, thiab qee zaum muaj me me ntawm ferrite.
304L Steel Txias Forming Performance
Txias txoj kev ua haujlwm ntawmSA 213 TP 304L tubeyog ib qho tseem ceeb qhia txog kev ntsuas seb qhov kev sib sau yog du thiab tus nqi tawm los. Txhawm rau kom tau txais kev ua haujlwm txias txias, cov chaw tsim khoom yuav tsum tswj qhov sib piv ntawm chromium sib npaug rau npib tsib xee sib npaug hauv cov hlau hauv qhov tsim nyog.
