S420NL phaj yog cov hlau zoo zoo, uas yog lub zog siab steel phaj raws li European tus qauv EN 10025.
S420NL steel phajNws muaj cov khoom siv ntau dua nyob rau hauv cov xwm txheej ntawm normalizing lossis normalizing ntxiv rau tempering.
Cov khoom thiab cov ntsiab lus ntawm S420NL cov khoom zoo ib yam li Q420E qib hauv Suav teb.
Dab tsi yog qhov txawv ntawmS420N daim hlauthiab S420NL steel phaj
S420 steel phaj yuav tsum tau muab cais ua alloy tshwj xeeb hlau. S420 steel yog muab rau hauv cov qib hauv qab no: thaum qhov kub tsis qis dua - 20 degree, qhov tsawg kawg nkaus tus nqi ntawm qhov cuam tshuam lub zog yog qhia los ntawm N, uas yog S420N. Thaum qhov kub tsis qis dua - 50 degree, qhov tsawg kawg nkaus cuam tshuam lub zog yog qhia los ntawm NL, uas yog S420NL.

FAQ
Q: Cov khoom siv S420NL yog dab tsi?
A: S420NL steel yog ib qho zoo weldability structural steel qib. Cov kev cai dav dav rau arc vuam ntawm cov hlau tau teev tseg yuav tsum yog raws li tau muab hauv EN 1011-2. Muab piv rau S355N, S420NL steel qib muaj ntau qhov tawm los thiab lub zog tensile. Qib sib npaug ntawm S420NL yog S420ML.
Q: Cov khoom siv qib S420 yog dab tsi?
A: S420 Cov qauv steels qib yog lub zog siab weldable zoo lis cov qauv hlau. Txhua qib tuaj yeem tau txais nrog cov khoom pov thawj cuam tshuam ntawm -20℃(N lossis M qib), lossis rau cov ntawv thov kub ntawm -50℃(NL lossis ML qib).
