Ntawm no yog cov paub meej ntxiv ntawm Q550NHERDER STEEL qhov kev cuam tshuam nyuaj ua kev ua haujlwm hauv qis- qhov chaw ib puag ncig (-40 degree):
Cov Khoom Siv Cov Lus Qhia thiab Cov Qauv
Raws li GB / T 4171, Q550NH yog yuav tsum tau tswj hwm ntau dua lossis sib npaug ntawm 27}} negch cuam tshuam lub zog ntawm 0 degree
Tus qauv tsis qhia kom meej txog cov kev pabcuam -40
Cov kev hloov kho ib txwm muaj xws li thermiechaanical tswj kev ua (TMCP) lossis li qub
Tsawg - kub cov yam kub kev kub ntxhov
Puag hlau Toughness ntawm -40 Qib Feem Ntau Nyob Ntawm 20-40J
Lub Zas - rau -} brsttle hloov kub (DBTT) feem ntau tshwm sim ntawm-50 degree
Weld cua sov -} cuam tshuam zones (Haz) muab txo qis (feem ntau 40-50% qis dua li paus hlau)
Yam cuam tshuam rau -40℃kev ua tau zoo
Microstructure: nplua {{0} nplej ferrite - pumblt qauv ua tau zoo dua
Thickness: Thicker sections (>25mm) pom tau ntau cov lus nrawm nrawm
Tshuaj lom neeg tshuaj lom neeg: ntau dua cov ntsiab lus Nickel (NI) cov ntsiab lus txhim kho qis - kub ua tau zoo
Kev Ua: TMCP cov khoom siv feem ntau outperforms li - rolled cov khoom
Txhim Kho Txoj Kev
Nickel alloying (0.5-1.5% ni ntxiv)
Post - Weld Kev Kho Mob Cua Sov (PWHT) rau cov sib koom tes tseem ceeb welded
Nruj tswj ntawm vuam tsis thiab cov lus qhia tshav kub
Siv Weathering - Tsis kam ua cov hlau
Kev txiav txim siab tsim
Rau -} Cov kev pabcuam 40 degree, qhia meej NI-hloov Q550NH (yog tias muaj)
Counts Project -} Kev Ntsuas Kev Pov Hwm Tshwj Xeeb
Zam kev ntxhov siab hauv kev tsim qauv
Txiav txim siab cov cua sov hauv zos rau cov khoom tseem ceeb
Cov ntaub ntawv pov thawj:
Kev xeem yuav tsum tau ua raws li GB / T 229 lossis ISO 148
Yam tsawg kawg 3 cov hnoos qeev rau ib qho kev sim mob
Kev kuaj yuav tsum muaj ob qho tib si cov hlau thiab cov qauv welded
Cov ntawv thov raug ntawm -40 degree:
Arctic Infrasure
Txias cia khoom
High -} agitude qauv
Cov Khoom Tshwj Xeeb Cov Khoom Siv Tshwj Xeeb
