Lub Zog Kho Tshuab thiab Kev Cuam Tshuam Toughness ntawm ABS AH36 Steel Phaj

Nyob rau hauv thaj teb ntawmkev tsim nkoj thiab kev tsim kho hauv hiav txwv, cov ntaub ntawv qauv raug rau qee qhov xwm txheej nyuaj tshaj plaws uas xav tau - kev ntxhov siab siab, kev thauj khoom dynamic, thiab cov dej hiav txwv corrosive. Lub peev xwm ntawm cov khoom siv los ua haujlwm tau zoo nyob rau hauv cov xwm txheej zoo li no yog txhais los ntawm ob qho tseem ceeb:lub zog kho tshuabthiabkev cuam tshuam tawv.

Ntawm cov hlau marine uas ntseeg siab tshaj plaws uas siv thoob ntiaj teb,ABS AH36 hlau phajtau tsim lawv tus kheej ua tus qauv raukev ua tau zoo ntawm cov qauv muaj zogCov phaj no siv dav hauv kev tsim kholub cev nkoj, cov platforms offshore, thiab cov khoom siv marine, muab kev sib txuas zoo heev, kev tiv thaiv corrosion, thiab kev kub tsawg.

Ua ib lub tuam txhab muab khoom siv hlau marine thiab industrial uas tau ntawv pov thawj thoob ntiaj teb,sakysteelmuab cov qib siab tshaj plawsABSAH36 hlau phajuas ua tau raws li cov qauv nruj ntawmLub Chaw Haujlwm Saib Xyuas Kev Thauj Khoom Hauv Tebchaws Meskas (ABS), ua kom muaj kev ruaj khov, kev nyab xeeb, thiab kev ntseeg siab rau txhua daim ntawv thov hauv hiav txwv.

ABS AH36 Hlau Yog Dab Tsi?

ABS AH36yog ib qhocov hlau ua los ntawm cov hlau uas muaj zog heev, tsis tshua muaj hlau sib xyawtsim tshwj xeeb rau kev tsim nkoj thiab kev tsim kho dej hiav txwv. Nws yog ib feem ntawmASTM A131 / ABS Qib A series, tsim los kom tiv taus cov xwm txheej nyuaj uas cov nkoj hla dej hiav txwv thiab cov platforms offshore ntsib.

Lub cim "AH" qhia tias cov khoom siv no yog siv rau hauvib puag ncig kub ib txwm muaj(kev sim cuam tshuam ntawm 0 ° C), thaum "36" hais txog nwslub zog tsawg kawg nkaus ntawm 355 MPa (kwv yees li 36 ksi).

Qhov kev sib xyaw ua ke ntawmlub zog, ductility, thiab kev cuam tshuam tsis kamua rau AH36 hlau yog ib qho ntawm cov ntaub ntawv nyiam tshaj plaws rau kev tsim cov nkoj ruaj khov thiab cov khoom thauj khoom.

Cov Tshuaj Lom Zem ntawm ABS AH36 Steel

Cov khoom sib xyaw ntawm AH36 raug tswj kom zoo kom muaj kev sib npaug ntawmlub zog kho tshuab, kev tiv thaiv corrosion, thiab weldability.

Cov Tshuaj Muaj pes tsawg leeg (%):

  • Cov pa roj carbon (C):≤ 0.18

  • Manganese (Mn):0.90–1.60

  • Silicon (Si):0.10–0.50

  • Phosphorus (P):≤ 0.035

  • Sulfur (S):≤ 0.035

  • Niobium (Nb), Vanadium (V), Titanium (Ti):≤ 0.10

Microalloying nrog Nb, V, thiab Ti ua rau cov hlau zoo duakev ua kom zoo dua ntawm cov nplej, uas ua rau muaj kev tawv dua thiab zoo dua tiv taus kev tawg yooj yim hauv qab kev cuam tshuam.

Lub Zog Kho Tshuab ntawm ABS AH36 Steel Phaj

Lub ntsiab lus tseem ceeb ntawm AH36 yog nwslub zog kho tshuab siab, uas tso cai rau cov nkoj thiab cov qauv hauv hiav txwv kom tiv taus cov khoom thauj loj thiab cov zog khoov uas tsim los ntawm nthwv dej, khoom thauj, thiab cua siab.

Cov Khoom Siv Kho Tshuab Ib Txwm Muaj:

  • Lub Zog Tawm:≥ 355 MPa

  • Lub zog tensile:490–620 MPa

  • Kev ntev (hauv 50 hli):≥ 21%

  • Qhov nyuaj (HB):170–220

Qib zog no ua kom cov hlab ntsha tseem ua tau lawv txoj kev ruaj khov txawm tias nyob hauv qabhnyav load thiab deformationQhov kev sib xyaw ua ke ntawm cov qoob loo thiab lub zog tensile kuj ua rau cov engineers tsim taucov nkoj uas sib dua thiab siv roj tsawg duatsis muaj kev cuam tshuam rau kev nyab xeeb lossis kev ua tau zoo.

Kev Tiv Thaiv Siab

Cov phaj AH36 tau tsim los tswj cov kev ntxhov siab thiab kev ntxhov siab tensile uas tshwm sim thaum cov nkoj hla dej hiav txwv ntxhib. Lawv lub zog siab tshaj plaws tiv thaiv kev hloov pauv mus tas li ntawm lub cev nkoj lossis lub lawj.

Lub zog qaug zog

Cov nkoj thiab cov platforms offshore muaj kev ntxhov siab cyclic los ntawm nthwv dej thiab cov tshuab co. AH36 lub microstructure muabtxhim kho kev qaug zog tiv thaiv, tiv thaiv kev tawg me me thiab kev qaug zog ntawm cov qauv thaum lub sijhawm ua haujlwm ntev.

Kev Ruaj Ntseg ntawm Qhov Ntev

Txawm tias nyob rau hauv qhov kub thiab txias hloov pauv, AH36 tseem muaj qhov tseeb thiab ruaj khov zoo heev - qhov tseem ceeb rau kev sib dhos loj thiab kev tsim kho nkoj modular.

Kev Ruaj Ntseg: Qhov Tseem Ceeb rau Kev Nyab Xeeb ntawm Hiav Txwv

Kev cuam tshuam tawvyog lub peev xwm ntawm cov khoom siv los nqus lub zog thaum lub sijhawm thauj khoom sai sai lossis kev cuam tshuam yam tsis muaj kev tawg. Rau cov hlau ua nkoj xws li AH36, cov khoom no yog qhov tseem ceeb vim tias cov nkoj raug rau tas likev cuam tshuam ntawm nthwv dej, kev sib tsoo, thiab kev hloov pauv ntawm qhov kub thiab txias.

AH36 hlau raug kev txom nyemKev ntsuam xyuas kev cuam tshuam Charpy V-notch (CVN)kom ntseeg tau tias nws lub zog ua tau raws li cov qauv ABS nruj.

Cov Kev Cai rau Kev Ntsuas Kev Cuam Tshuam:

  • Kub Ntsuas:0°C

  • Lub Zog Cuam Tshuam Yam Tsawg Kawg Nkaus:34 Joules

Qhov no ua kom ntseeg tau tias txawm tias nyob hauvcov dej hiav txwv txias, AH36 khaws cia txaus ductility kom deform plastically es tsis txhob tawg brittlely - qhov tseem ceeb kev nyab xeeb rau cov qauv hull ua haujlwm hauv huab cua sib txawv.

1. Kev Ua Tau Kub Tsawg

Thaum qhov kub qis dua, feem ntau cov hlau ua rau tawg yooj yim. Txawm li cas los xij, AH36 cov qauv me me tso cai rau nws kom tswj tausiab tawvntawm 0 ° C, kom ntseeg tau tias muaj kev ruaj khov ntawm cov qauv thaum lub sijhawm Arctic lossis huab cua txias.

2. Kev Nqus Zog Thaum Lub Sijhawm Sib Tsoo

Lub zog nqus tau ntawm cov hlau no ua rau muaj kev puas tsuaj tsawg dua yog tias muajkev sib tsoo ntawm lub nkoj lossis kev sib cuag nrog cov khib nyiab uas ntab dej, txo qhov kev pheej hmoo ntawm kev ua tsis tiav loj heev.

3. Kev Tiv Thaiv Kev Tawg Nthuav Dav

Cov khoom siv microalloying xws li niobium thiab vanadium pab txhawb rau kev ua haujlwm ntawm cov khoom siv microalloying.cov qauv nplej tawv, ua kom zoo nkauj, uas tiv taus qhov kis ntawm cov kab nrib pleb uas pib los ntawm kev ntxhov siab hauv zos lossis qaug zog.

4. Kev Nyab Xeeb Zoo Tshaj Plaws

Vim nws qhov kev sib xyaw ua ke ntawmlub zog thiab toughness ntawm cov khoom, AH36 muab kev nyab xeeb zoo dua tiv thaiv kev ntxhov siab ntawm lub cev lossis ib puag ncig uas tsis tuaj yeem kwv yees tau.

Kev Sib Piv: AH36 vs. Cov Hlau Marine Ordinary

Vaj tse Hlau Me (Qib A) AH36 Hlau
Lub Zog Tawm (MPa) 235 355
Lub zog Tensile (MPa) 400–520 490–620
Kub Ntsuas Kev Cuam Tshuam Kub Hauv Chav 0°C
Kev Tiv Thaiv Kev Xeb Nruab nrab Zoo heev
Kev Ua Haujlwm Zoo ntawm Qhov Hnyav Hnyav dua Sib zog dua rau tib lub zog

Qhov kev sib piv no qhia txog vim li cas AH36 thiaj li nyiam siv rau hauv kev tsim nkoj niaj hnub no - nws tso cai raucov phaj nyias dua, cov hulls sib dua, thiab kev siv roj zoo dua, tag nrho thaum tswj hwm lub zog tshwj xeeb thiab kev ua haujlwm ntev.
