FH36 Shipbuilding Steel Phaj - Siab -Lub Zog Marine & Offshore Steel
FH 36yog lub siab - zog, qis- alloy shipbuilding steel phaj ntawv pov thawj los ntawm cov koom haum loj (ABS, DNV, LR, CCS, BV, NK, RINA, RS). Nws belongs rau FH series raws li lub zog dav dav thiab siab - lub zog shipbuilding steel qauv.
Qhov "F" txhais tau tias qhov ntsuas qhov ntsuas kub ntawm qib:-60 degree, ua rau nws haum rau qhov hnyav tshaj plaws Arctic thiab polar kev pabcuam. "H36" qhia qhov tsawg kawg nkaus yield zog ntawm355 MPa rau(51,000 psi) thiab tensile lub zog ntawm490-620 MPa.
FH36 feem ntau yog siv rau cov txheej txheem tseem ceeb hauv cov nkoj, cov chaw sab nrauv, thiab cov khoom siv hauv hiav txwv ua haujlwm hauv qhov chaw qis heev - qhov kub thiab txias.

Ntau yam kev xa khoom- Raws li kev cai, TMCP, lossis QT kev xaiv kom haum rau cov kev xav tau sib txawv.
Siab zog - rau - Qhov hnyav piv- Ua kom cov qauv tsim qauv sib dua yam tsis muaj kev nyab xeeb.
Weldability zoo heev- Tsawg carbon sib npaug tso cai rau preheating thiab vuam yam tsis muaj cracking, txawm nyob rau hauv tuab seem.
Fatigue & Corrosion Resistance- Haum rau shipload cyclic stresses thiab dej ntsev raug.
Certified los ntawm Txhua Lub Koom Haum Loj- ABS, DNV, LR, CCS, BV, NK, RINA, RS, thiab lwm yam.

FAQ
01.Dab tsi yog qhov txawv ntawm FH36 thiab DH36 steel phaj?
Qhov sib txawv tseem ceeb yog qhovcuam tshuam qhov ntsuas kub.
DH 36yog kuaj ntawm-20 degreethiab haum rau txias tab sis tsis yog - ib puag ncig Arctic (xws li North Hiav Txwv, Baltic Hiav Txwv).
FH 36yog kuaj ntawm-60 degree, ua rau nws nyiam xaiv rauCov nkoj hauv Arctic, cov dej khov nab kuab, thiab cov polar-chav kawm offshore platforms.
Ob qib muaj qhov tsawg kawg nkaus tawm lub zog (355 MPa), tab sis FH36 muaj qhov zoo tshaj qhov qis dua - qhov kub thiab txias.
02.Dab tsi thicknesses ntawm FH36 steel phaj muaj nyob rau hauv shipbuilding?
Common shipbuilding thicknesses muaj los ntawm8mm txog 80mm. Kev cai thicknesses thiab txiav - mus rau - daim hlau loj kuj muaj raws li qhov kev thov.
03.Qhov kev faib pawg twg tau lees paub FH36 steel phaj?
FH36 tuaj yeem raug lees paub los ntawm txhua lub koom haum kev faib loj, suav nrog tab sis tsis txwv rau:
ABS(American Bureau of Shipping)
DNV(NWS Norske Veritas)
LR(Lloyd's Register)
CCS(Tuam Tshoj Classification Society)
BV(Bureau Veritas)
NK(Nippon Kaiji Kyokai / ClassNK)
RINA(Rau npe Italiano Navale)
RS(Russian Maritime Register of Shipping)
Koj tuaj yeem thov kev pom zoo hauv chav kawm tshwj xeeb thaum tso koj daim ntawv xaj.
04.FH36 steel phaj puas tuaj yeem welded yam tsis muaj preheating?
FH36 muaj qhov sib npaug qis carbon (feem ntau Tsawg dua lossis sib npaug rau 0.38), uas muabzoo weldability.
Txawm li cas los xij, rau cov phaj tuab (piv txwv li, Ntau dua lossis sib npaug li 40 mm) lossis nyob rau hauv qhov kub thiab txias,preheating (feem ntau 50-100 degree)raug pom zoo los tiv thaiv hydrogen -induced cracking.
Cov txheej txheem vuam tsim nyog (WPS) yuav tsum ua raws li. Peb muab WPS kev taw qhia pub dawb thaum thov.
