S420NLH carbon steel yeeb nkab yog zoo-grained seamless steel yeeb nkab khoom rau steel qauv nrog siab zog thiab zoo kub tsis tshua muaj kev cuam tshuam toughness. "S" sawv cev rau cov qauv hlau, "420" txhais tau hais tias nws qhov tsawg kawg nkaus tawm lub zog yog 420MPa thaum cov phab ntsa thickness tsawg dua los yog sib npaug rau 16 hli, thiab "N" txhais tau tias normalizing lossis normalizing dov.
Kub dov yog cov txheej txheem tseem ceeb ntawm S420NLH qib kub tiav cov yeeb nkab. Los ntawm cov txheej txheem kub dov, cov hlau tuaj yeem tau zoo plasticity thiab toughness, thaum txhim kho lub zog thiab hardness ntawm cov hlau.
EN 10210-1 S420NLH steel yeeb nkab muab los ntawm GNEE yog muaj nyob rau hauv seamless, welded, ERW, EFW yeeb nkab thiab lwm yam. EN 10210-1 S420NLH welded yeeb nkab muaj zog dua seamless yeeb nkab, tab sis muaj ntau dua qhov roughness. Cov khoom siv tuaj yeem ua tau zoo los yog kev ntxhov siab.
