Siab zog steel phaj Q420B
Q420B high-strength steel phaj yog cov hlau tsis tshua muaj hlau uas muaj zog nrog cov khoom siv zoo heev thiab ntau yam kev siv.
Q420B cov hlau tsis tshua muaj hlau tsis yog tsuas yog muaj lub zog siab, tab sis kuj muaj qhov zoo toughness, thiab tuaj yeem tswj tau qhov kev ncaj ncees thiab kev ruaj ntseg ntawm cov qauv thaum muaj kev cuam tshuam loj. Nyob rau tib lub sijhawm, Q420B siab tensile steel phaj muaj qhov zoo vuam kev ua tau zoo, tuaj yeem welded ntawm qhov kub thiab txias, thiab tsis ua rau muaj qhov tsis xws luag xws li tawg tom qab vuam.
GNEE yog ib lub chaw tsim khoom ntawm huab cua steel phaj nrog 17 xyoo ntawm kev tsim khoom. Lub siab tensile steel phaj peb muab tau nruj me ntsis ua raws li cov qauv, dhau daim ntawv pov thawj zoo, tuaj yeem muab cov ntawv pov thawj zoo, thiab lees txais kev kuaj thib peb.
Peb tuaj yeem tsis tsuas yog muab lub zog siab qis alloy steel ntawm ntau yam tshwj xeeb thiab qhov ntau thiab tsawg, tab sis kuj A709 Qib 50 qib steel, cov khoom siv zoo steel hlau S355J2, S690QL1 cov qauv hlau phaj. Tsis tas li ntawd, cov khoom uas peb muab tuaj yeem muab qhov loj me thiab ntau yam kev pabcuam raws li koj qhov kev xav tau kawg.
