Cov hlau tshwj xeeb rau ultra- cov hlab ntsha kub siab: 07Ni5DR

Lub ntsiab lus ntawm qib:

"07" qhia tias cov ntsiab lus carbon (C) tsawg dua lossis sib npaug li 0.07%;

"Ni5" qhia tias qhov nruab nrab cov ntsiab lus ntawm nickel (Ni) yog 4.75% ~ 5.25%;

"DR" yog lub ntsiab lus ntawm "low{0}}kub lub nkoj".

07Ni5DR steel phaj yog npib tsib xee alloy steel phaj nrog qis -kev ua haujlwm kub, tseem hu ua 5Ni steel lossis 9Ni steel. Nrog nws cov tshuaj lom neeg muaj pes tsawg leeg thiab cov khoom zoo ntawm lub cev thiab cov khoom siv kho tshuab, nws yog dav siv nyob rau hauv ntau qhov chaw ua lag luam, thiab tshwj xeeb tshaj yog tsim rau kev tsim cov khoom qis - kub siab.

Cov ntsiab lus tseem ceeb:

• Nickel (Ni): 4.75% ~ 5.25% (core alloying caij);

• Carbon (C): Tsawg dua lossis sib npaug li 0.10%;

• Silicon (Si): 0.10% ~ 0.35%;

• Manganese (Mn): 0.30% ~ 0.80%;

Lwm cov ntsiab lus alloying muaj xws li chromium (Cr), tooj liab (Cu), molybdenum (Mo), vanadium (V), niobium (Nb), thiab lwm yam., tag nrho cov no yog tswj los ntawm qib qis.

Tsawg-kev ua haujlwm kub:
Qhov tsawg kawg nkaus kev pabcuam kub tuaj yeem ncav cuag -120 degree, tswj kom muaj kev cuam tshuam zoo thiab cov khoom siv kho tshuab;
Ua raws li tus qauv GB/T 713.4-2023 (zoo txij lub Peb Hlis 2024).

Mechanical Properties:
Tensile zog: 530 ~ 700MPa;
Yield zog: Ntau tshaj los yog sib npaug rau 370MPa rau thickness 5 ~ 30mm, Ntau tshaj los yog sib npaug rau 360MPa rau 30 ~ 50mm, Ntau tshaj los yog sib npaug rau 350MPa rau 50 ~ 80mm;
Elongation: Ntau dua lossis sib npaug li 20%.

Lwm yam ntxwv:
Weldability zoo heev thiab corrosion kuj (resistant rau acids, alkalis, thiab lwm yam);
Superior thermal conductivity, uas pab tswj qhov kub thiab txias hauv lub nkoj.

Core Fields:

• Ultra- cov nkoj uas tsis tshua muaj siab rau LNG cia tanks thiab LNG nkoj;
• Tsawg- cov khoom siv kub hauv tshuaj lom neeg, roj av, marine engineering, nuclear zog thiab lwm yam lag luam (xws li CO₂ absorption towers, methanol ntxhua khaub ncaws).

Feem ntau xa hauv lub xeev ntawm offline quenching + tempering. Rau thickness tsawg dua los yog sib npaug rau 12 hli, cov txheej txheem ntawm ob chav normalizing + tempering yuav tau txais yuav, nrog rau tempering kub tsis qis tshaj 540 degree.

GNEE cov neeg koom nrog kab lis kev cai hais txog "ua tiav cov neeg siv khoom thiab ua rau cov neeg ua haujlwm zoo siab". Peb ua raws li qhov tseem ceeb ntawm "kev lees txais kev hloov pauv thiab kev lav phib xaub hauv kev ua; tsis muaj qhov zoo tshaj plaws, tsuas yog zoo dua", txhawb cov neeg ua haujlwm kom ua tiav qhov zoo thiab ua kom muaj kev vam meej. Lub tuam txhab tsis tsuas yog tsom mus rau kev txhim kho kev ua haujlwm ntawm pab pawg, tab sis tseem mob siab rau kev loj hlob ntawm tus kheej thiab kev zoo siab ntawm cov neeg ua haujlwm, sib zog ua kom muaj kev noj qab haus huv thiab kev sib haum xeeb ntawm kev ua haujlwm.
