TS EN 10025-3 S420N, S420N STEEL, S420N STEEL PLATE yuav tsum tau ua tiav kev kho cua sov raws li Normalized.Normalized dov txheej txheem nyob rau hauv uas qhov kawg deformation yog nqa tawm nyob rau hauv ib tug tej yam kub qhov ntau yam uas ua rau ib tug tej yam kev mob ntawm cov khoom sib npaug rau cov uas tau txais tom qab normalizing thiaj li hais tias tus nqi ntawm cov cuab yeej cuab tam tom qab retains. Hauv kev tshaj tawm thoob ntiaj teb rau ob qho tib si rau kev ua kom zoo dua qub rau steel phaj s420n, nrog rau cov thermomechanical dov, cov lus qhia "tswj dov" tuaj yeem pom. Txawm li cas los xij, nyob rau hauv kev pom ntawm qhov sib txawv ntawm cov khoom siv, qhov sib txawv ntawm cov ntsiab lus yog qhov tsim nyog.
