Q295NH ZWJ HUAM HLAU HLAU PHAJyog ib qho kev ua tau zoo ntawm cov khoom siv ua rau cov khoom siv hluav taws xob thiab cov ntawv thov marrine, sib txuasmarine-qib corrosion tsis kamnrog cov khoom siv muaj zog. Tsim nyob rau hauvGB / T 4171Txheem, cov hlau roj tsawg-allolo nta muaj cov tswv yim sib xyaw ntawm alloy txheej, cov av noo, thiab cov purutants uas tsis muaj tshuaj lom tsis muaj kev tiv thaiv. Nws kev ua tau zoo rivalsASTM A588 CORTEN STEELTab sis yog qhov zoo rau Tuam Tshoj txoj kev ruaj khov thiab chaw nres nkoj ua kom muaj kev ntseeg tau, kom muaj kev cia siab rau hauv kev ua haujlwm hnyav.

Core zoo rau cov khoom siv hluav taws xob

Marine-qib corrosion tsis kam
Q295NH Steel lub cev muaj pes tsawg leeg txhawb nqa kev tsim cov txheej txheem ruaj khov, tsis muaj xeb, kev tsim txom hauv cov ntug dej hiav txwv thiab chaw nres nkoj. Qhov kev kho tus kheej kho tus kheej tau muab8 lub sij hawm ntau dua corrosion tsis kam dua li cov roj carbonnyob rau hauv cov ntsev-nraaj emospheres, raws li tau siv tau los ntawmASTM B117 Ntsev Tsuag Kev Tshuaj NtsuamCov. PATINA LUB RUGG RUGG RAWS LUAM TSEEM TSEEM CEEB Hawb Thaum Lub Caij Tsheb Cargo, Txo cov nqi tswj xyuas Cargo los ntawm kev pleev xim hlau.

Lub Zog Muaj Zog & Cov Khoom Siv Dynamic Log Muaj Peev Xwm
Nrog tsawg kawg yog cov txiaj ntsig lub zog ntawm295 MPathiab tensile lub zog xws li430-560 MPa, Q295NH cov hlau tau muab kev pab cuam tshwj xeeb rau chaw nres nkoj cranes, thawv thav duab, thiab cov tshuab ntxhua khaub ncaws. Nws tus nqi elongation ntawm ntau dua los yog sib npaug rau 22% ua kom muaj kev cuam tshuam nrog 27 J ntawm -20 degree) lav tau tias muaj mob heev lossis muaj kev cuam tshuam ntau. Qhov kev siv hluav taws xob muaj zog no txo cov nqi txo los ntawm li 15%, ua kom muaj roj tshuab hluav taws xob hauv Txawb tshuab.

Weldability & Fabrication Yooj Yim
Q295NH STEEL txhawb Seamless Vuam siv cov qauv mig / mag lossis arc vuam cov txheej txheem (CE tsawg dua lossis sib npaug ntawm cov kev pheej hmoo ntawm hydrogen-inducts cracking. Rau cov ntawv thov chaw nres nkoj, npaj ua ntej weld cuam tshuam nrog rust nto xeb tsis pub dhau 10-20mm ntawm cov npoo sib koom tes kom paub meej Wolding ncaj ncees. Kev siv ntawmE7018 Cov Hluav Taws Xob Cov Hluav Taws Xobyog pom zoo kom tswj kev txhim kho corrosion hauv cov pob qij txha tseem ceeb, xws li crane booms lossis thawv xauv. Cov hlau txias cov khoom txias kuj tseem ua kom meej meej meej ntawm cov khoom siv nyuaj, xws li Kenned Cesining nkhaus rau cov thawv xa khoom.

Kev ruaj khov & Ntev
Nyob rau hauv cov tub rog mob tsheb lojNtau dua los yog sib npaug rau 30 xyooNrog kev txij nkawm tsawg kawg, txo lub neej ib puag ncig ib puag ncig ib puag ncig. Lub Patina lub ntuj kev laus ua rau muaj kev cia siab rau cov tshuaj lom neeg siv tshuaj lom neeg, sib thooj nrog cov hom phiaj hauv ntiaj teb. Qhov kev siv hluav taws xob no yog pov thawj hauv cov ntawv thov nyiam chaw nres nkoj crane undercarrises thiab marine bollards, qhov twg nws withstands ntawm nthuav tawm rau ntsev mer thiab kev ntxhov siab.

Kev Ua Tshwj Xeeb

Chaw nres nkoj & Chine Daim Ntawv Thov

Thawv Cov Khoom Siv Ntaus: Tiv thaiv kom muaj kev puas tsuaj los ntawm cargo thiab corrosion los ntawm de-icing tshuaj chemical nyob rau hauv crane log hauv crane log thiab spreip tuav.

Tubrog nkoj: Ruaj ruaj rau cov chaw fender, gangways, thiab mooring posts hauv qab ntsev ib puag ncig.

Tej Tshuab: Siv nyob rau hauv ciblauvor cov menyuam thiab Hopper kev txhim kho raug rau corrosive ntxhia pob zeb plua plav.

Cov Khoom Siv Hluav Taws Xob: Lub teeb yuag tam sim no tseem muaj zog rau cov khoom thauj khoom thiab lawj kev txhawb nqa hauv cov nkoj ntawm ntug hiav txwv.

Kev Muaj Peev Xwm Zoo

Tsim nyob rau hauv ISO-tau lees paub cov chaw, Q295NHN steel daim phiaj seeding, suav nrog tensile, khoov, thiab ntsev tsuag tsuag, thiab ntsev tsuag tsuag. Cov ntawv pov thawj thib peb (en {4 4}}}}}}}}}}}}}}}}}}} / 3.2) thiab corrosion Kuj tseem muaj cov lus nug thov. Cov kev daws teeb meem, xws li ua ntej hnub nyoog patina tiav los yog txiav-loj-rau-loj daim phiaj rau nkhaus nrog chaw nres nkoj tsim specifications.

Vim li cas thiaj xaiv Q295NHing rau cov khoom siv chaw nres nkoj thiab cov khoom lag luam?
