P275NL1 siab lub nkoj steel phaj nthuav dav qhia
P275NL1 yog cov phaj hlau rau cov hlab ntsha uas muaj qhov kub thiab txias uas tau teev tseg hauv European tus qauv EN 10028-3. Cov hlau phaj muaj cov ductility siab, plasticity thiab toughness, thiab muaj peev xwm tuav tau zoo zog thiab corrosion kuj ntawm qhov kub thiab txias. P275NL1 European txheem phaj yog tsuas yog siv rau hauv kev tsim cov hlab ntsha thiab cov kav dej hauv cov roj av, tshuaj lom neeg, roj thiab lwm yam lag luam.
Kev xa khoom raws li txoj cai ntawm P275NL1 steel phaj Xa khoom raws li txoj cai
tus me nyuam nyob rau hauv normalizing tshav kub kho lub xeev; Yog tias xav tau, thiab tus neeg yuav khoom thiab tus tsim khoom tau kos npe rau daim ntawv cog lus, koj tuaj yeem xaiv normalize dov es tsis txhob normalizing tus me nyuam. Nyob rau hauv cov ntaub ntawv no, tus qauv raug sim nyob rau hauv ib tug simulated normalizing lub xeev los ua pov thawj tias qhov kev ua tau zoo raws li tau teev tseg, thiab lub xeem zaus yuav sib tham nyob rau hauv lub sij hawm ntawm kev txiav txim thiab nug.
Kev ua tau zoo ntawm P275NL1 European standard board
P275NL1 European txheem phaj yog cov hlau tsis tshua muaj carbon hlau, nws cov khoom tseem ceeb muaj xws li carbon, silicon, manganese, phosphorus, sulfur thiab me me ntawm chromium, molybdenum thiab lwm yam khoom.
Cov hlau no muaj lub zog siab, zoo toughness thiab weldability, nrog rau zoo heev corrosion kuj thiab tsis kam mus rau hydrogen cracking. Lub zog tawm los mus txog 275MPa, lub zog tensile nyob nruab nrab ntawm 410-550MPa, thiab elongation tsis tsawg dua 21%.
Qhov luaj li cas, cov duab thiab qhov sib txawv ntawm cov hlau phaj yuav tsum ua raws li cov kev cai ntawm 2007+ A1:2009 hauv EN10028-1
EN10028-3 suav nrog cov qib hauv qab no: P275NH, P275NL1, P275NL2, P355N, P355NH, P355NL1, P460NH.P460NL1, P460NL2
