DESCRIPTION:
Submerged Arc Cored Wires Tsawg-Alloy Steel
CATEGORY:
AWS A5.23: ECM4 Submerged Arc Solid Wire is a low-alloy composite metal-cored wire electrode for submerged arc welding in high strength applications.AWS A5.23: ECM4 ntsib AWS A5.23 chemistry M4, thiab yog tsim los rau qib tensile zog siab tshaj 110 ksi.
MAIN APPLICATION:
Daim ntawv thov ib leeg thiab ntau dhau nrog kev pom zoo submerged arc flux, High-Strength Low-Alloy steels, Quench & Tempered steels, Heavy khoom Cheebtsam, structural Cheebtsam, nkoj hulls, cam khwb cia hlau, boiler & siab hlab ntsha
HSLA thiab Q&T steels
Kev tsim qauv tsim
Jack-up rig fabrication
Cov khoom siv hnyav hnyav
Crane kab teeb
NTA:
Hlau-cored hlau tuaj yeem muab cov txiaj ntsig zoo dua piv rau cov xaim khoom ntawm qhov sib piv amperages
Hlau-cored nyob ntawm tej muaj dav dav penetrationprofiles piv rau cov khoom nyob ntawm tej yam uas tsis zoo sib xws
Lub zog siab heev deposit nrog zoo heev low-temperature toughness nyob rau hauv raws li-welded Condition
Weld deposit chemistry yuav tsum zoo ib yam rau cov EM4 cov xov hlau
