FH32 Shipbuilding Steel Phaj yog dab tsi?

FH32 yog qib siab -Shipbuilding steel qib nyob rau hauv cov kev cai ntawm kev faib loj hauv zej zog (ABS, DNV, LR, CCS, BV, KR, NK, RINA). Lub "F" sawv rau qhov kub tsis kam (-60 degree), "H" rau siab tensile zog (yield zog Ntau tshaj los yog sib npaug rau 315 MPa), thiab "32" rau qhov tsawg kawg nkaus yield zog nyob rau hauv Ksi.

Cov yam ntxwv tseem ceeb:

Tsawg kub toughness:Zoo heev Charpy V-Notch (CVN) cuam tshuam lub zog ntawm-60 degree.

Siab zog:Yield Strength Ntau dua los yog sib npaug rau 315 MPa, Tensile Strength 440-570 MPa.

Pom zoo los ntawm Major Class Societies:Haum rau kev tsim khoom nkoj thiab cov dej hiav txwv thoob ntiaj teb.

YuavABS FH32 Hlau Phajnrog -60℃Toughness

Ib - nres kev yuav khoom steel

Zoo heev -60℃Low-Temperature Impact Toughness (Zoo heev CVN): FH32 steel phaj yog tsim tshwj xeeb rauPolar Class VesselsthiabLNG cab kuj. Tsis zoo li cov qauv A lossis D qib steels, FH32 tuav lub siab Charpy V-Notch (CVN) cuam tshuam lub zog ntawmYam tsawg kawg 34 Joules ntawm -60 degree. Qhov no ua kom tsis muaj kev puas tsuaj hauv qhov tsis zoo hauv sub- xoom ib puag ncig, ua rau nws yog qhov yuav tsum tau xaiv rau cov dej khov thiab cov qauv hauv ntug dej hiav txwv hauv Arctic Circle.

Ntau-Kev Pom Zoo Hom Hauv Zej Zog (ABS, DNV, LR, CCS Certified): Peb muab FH32 steel phaj nrogtag nrho traceability thiab thawj 3.1 Mill Test Certificate (MTC)lees paub los ntawm txhua lub koom haum kev faib loj xws liABS, DNV, LR, CCS, BV, thiab NK. Qhov kev pom zoo no ntau -kev pom zoo hauv zej zog tso cai rau cov chaw nres nkoj siv peb daim phiaj rau txhua qhov haujlwm thoob ntiaj teb yam tsis muaj kev tsim nyog, txo qis sijhawm soj ntsuam thiab cov ntaub ntawv tus nqi rau koj pab neeg yuav khoom.

Optimized Weldability & TMCP Xa Lub Xeev: Txhawm rau kom muaj kev ua haujlwm siab, peb FH32 shipbuilding steel phaj nta qisCarbon Equivalent (CEV)thiab muaj nyob rau hauvTMCP (Thermo-Cov Txheej Txheem Kev Tswj Xyuas Tshuab)lub xeev xa khoom. TMCP tso cai rau lub zog siab dua yam tsis muaj cov ntsiab lus alloying ntau dhau, ua rauzoo heev weldability(txo lub sij hawm preheating) thiab superior HAZ (Heat Afected Zone) toughness. Qhov no txhais tau ncaj qha rau cov nqi qis dua thiab kev sib dhos sai dua rau koj lub nkoj nkoj.

Procurement Manager, Arctic Shipyard, Russia

Peb tau siv koj cov FH32 TMCP steel daim hlau rau cov txheej txheem ntawm ntug dej hiav txwv. Piv nrog rau cov paib uas peb tau siv ua ntej, qhov sib npaug ntawm cov pa roj carbon qis ua rau muaj qhov sib txawv loj. Peb cov welders tsis xav tau preheating ntau, thiab HAZ toughness tom qab vuam yog zoo heev. Qhov no ib leeg cawm peb txog 20% ntawm cov nqi zog thiab cov khoom siv ntawm 500-tuj project. Zoo siab thiab xa khoom sai.

FAQ

01.Koj puas tuaj yeem muab FH32 nrog Z25 lossis Z35 khoom?

Yog lawm. Peb tuaj yeem muab FH32 nrog Z-kev taw qhia (Los ntawm-} tuab) cov khoom xws li FH32Z25 thiab FH32Z35, uas yog qhov tseem ceeb rau cov pob ntawm cov ntug dej hiav txwv los tiv thaiv lamellar tearing.

02.Qhov txawv ntawm FH32 thiab FH36 yog dab tsi?

Tus naj npawb qhia tias lub zog tawm los. FH32 muaj qhov tsawg kawg nkaus lub zog ntawm 315 MPa, thaum FH36 yog 355 MPa. Rau qhov kub tsis tshua muaj siab (-60 degree), ob qho tib si ua tau zoo, tab sis FH36 yog lub luag haujlwm hnyav dua. Peb muab ob qho tib si.

03.Koj puas muab kev pabcuam txiav?

Yog, peb muab precision txiav cov kev pab cuam. Peb tuaj yeem txiav FH32 daim hlau rau koj daim duab kos ua ntej xa khoom, txuag koj lub sijhawm ua haujlwm.

04.Lub sij hawm xa khoom ntev npaum li cas rau FH32 steel?

Rau cov khoom loj, cov khoom xa tuaj tuaj yeem npaj tau hauv 7-14 hnub. Rau kev txiav txim loj loj, nws feem ntau yog 30-45 hnub tom qab tso nyiaj.
