- Q- quenched thiab tempered khoom xa tuaj
S890Q steel phaj yog feem ntau nkag rau hauvkub dov + Q&T mob, muab lub zog zoo heev, tswj kev toughness, thiab kev tsim khoom zoo thaum siv cov txheej txheem raug.
Cov yam ntxwv tseem ceeb ntawm Steel S890Q
Steel S890Q yog cais raws li quenched thiab tempered siab - lub zog structural steel raws li EN 10025-6 cov qauv, thiab nws cov yam ntxwv tseem ceeb muaj feem xyuam nrog nws cov txheej txheem ntau lawm thiab tshuaj muaj pes tsawg leeg:
Ua ntej,nws muaj zoo heevsiab -kev ua tau zoo. Cov txheej txheem quenching thiab tempering endows S890Q nrog ultra- siab tawm lub zog thiab tensile lub zog, uas tuaj yeem txo qhov hnyav ntawm cov khoom siv thaum ua kom cov load-cov kabmob muaj peev xwm, ua rau nws zoo tagnrho rau kev tsim qauv ntawm cov tshuab hnyav.
Thib ob,nws muaj qhov zooweldability. Tsis zoo li qee qhov siab - lub zog steels uas nyuaj rau welding, S890Q tuaj yeem ua tiav los ntawm cov txheej txheem vuam (xws li arc vuam, roj tiv thaiv vuam) tom qab preheating kom zoo, tsis muaj qhov pom tseeb vuam tsis xws luag.
Peb,nws muaj kev ntseeg siablow -kub toughness. Nws tswj cov kev cuam tshuam ruaj khov txawm tias nyob hauv qhov chaw qis - qhov kub thiab txias (txog rau -40 degree), uas yog qhov tseem ceeb rau kev siv hauv thaj chaw txias lossis kub kub ua haujlwm.
Ntxiv rau,S890Q muaj qhov sib xwsmicrostructurethiab kev ua haujlwm ruaj khov, nrog qhov sib txawv me me ntawm cov khoom siv kho tshuab ntawm cov khoom sib txawv, kom ntseeg tau qhov sib xws hauv kev tsim khoom.

Kev txiav txim siab vuam
Txawm hais tias S890Q yog ib lub siab - lub zog steel, nws tuaj yeem welded yam xyuam xim los ntawm:
Siv cov khoom siv hluav taws xob tsawg- hydrogen welding
Ua kom haum preheating nyob ntawm thickness
Tswj cov khoom siv hluav taws xob kom tswj tau qhov toughness
Ua raws li cov txheej txheem vuam pom zoo (WPS)
GNEE Steel muabkev txhawb nqalos xyuas kom meej qhov zoo tshaj plaws fabrication tau.
