Product Overview
Peb DNV-GL Hull Structural Steel Phaj yog tsim los rau kev tsim cov nkoj, cov qauv sab nrauv, thiab cov ntawv thov kev lag luam hauv hiav txwv uas yuav tsum tau muaj ntawv pov thawj kev ua haujlwm. Ua los ntawm kev tswj cov dov, TMCP, lossis kev ua haujlwm ib txwm ua raws li qib yuav tsum tau ua, cov phiaj no muab lub zog ruaj khov, weldability, thiab qis - qhov kub thiab txias rau qhov xav tau ib puag ncig marine.

Technical Advantage
Tsim los nrog cov pa roj carbon tsawg (Ceq Tsawg dua lossis sib npaug li 0.38%) los pab txo cov nqi ua ntej- cua sov thaum lub caij nkoj vuam thiab txo qhov txias txias - kev pheej hmoo tawg.
Refined los ntawm lub tshuab nqus tsev degassing kom tsis txhob muaj leej faj thiab phosphorus, txhawb kev ruaj khov Charpy V-notch cuam tshuam toughness mus rau -40℃rau EH/FH qib.
Cov txheej txheem siv 4-siab reversing dov mills kom nruj thickness thiab flatness tolerances haum rau automated CNC txiav kab.
Tshawb xyuas los ntawm 100% tag nrho-plate ultrasonic kuaj raws li cov qauv xws li ASTM A578 lossis EN 10160 kom txo qis kev txhawj xeeb hauv lamination ua ntej fabrication.
