DH32 steel phaj yog lub siab-zog qauv hlau phaj siv hauv kev lag luam nkoj. Nws cov tshuaj lom neeg muaj pes tsawg leeg feem ntau suav nrog cov ntsiab lus hauv qab no:
- Cov pa roj carbon (c)) (c) Cov ntsiab lus yuav tsum yog nruab nrab ntawm 0. 18-0. 21.
- Silicon (Si) cov ntsiab lus yuav tsum yog nruab nrab ntawm 0. 10-0. 50.
- MANGANUSE (MN) cov ntsiab lus yuav tsum yog nruab nrab ntawm 0. 90-1. 60.
- Phosphorus (p) cov ntsiab lus yuav tsum tsis pub tshaj 0. 035.
- Sulfur (s) cov ntsiab lus yuav tsum tsis pub tshaj 0. 035.
- Tooj liab (CU) cov ntsiab lus yuav tsum tsis pub tshaj 0. 35.
- Chromium (CR) cov ntsiab lus yuav tsum tsis pub tshaj 0. 20.
- Nickel (NI) cov ntsiab lus yuav tsum tsis pub tshaj 0. 40.
- Vanadium (v) cov ntsiab lus yuav tsum yog nruab nrab ntawm 0. 02-0. 05.
DH32 Hlau Hlau yog lub siab-zog qauv hlau hlau phaj nrog cov kev ua haujlwm hauv qab no:
1. Tensile lub zog: qhov tsawg kawg nkaus tensile muaj zog yog 490-620 mpa. Qhov no txhais tau tias DH32 cov phiaj hlau tuaj yeem tiv thaiv lub siab tensile loads.
2. Tawm lub zog: ntawm qhov kub ib txwm, cov txiaj ntsig lub zog yog 355 MPa, tseem hu ua qhov tsawg kawg nkaus muaj zog. Qhov no txhais tau tias thaum siv dag zog siv, cov hlau phaj pib ua kom plhaw.
3. Ej thaum so: Qhov tsawg kawg nkaus elongation thaum tawg yog 21%. Qhov no txhais tau tias thaum lub sijhawm DH36 steel hlau tuaj yeem plastically decorm rau ib yam uas tsis muaj tawg.
4. Tej zaum cov khoom nyuaj: DH36 steel phaj muaj cov xwm txheej zoo thiab yog qhov haum rau cov chaw ua haujlwm kub tsawg. Feem ntau, kev cuam tshuam tawv nruj yog yuav tsum tau ntsib cov kev mob tshwj xeeb, xws li {{2} {{}}}} degree.
.
DH32 daim phiaj tau dav siv nyob rau hauv nkoj thiab marine engineering thiab lwm cov teb, thiab feem ntau yog siv los tsim HULL qauv qauv thiab cov khoom siv ntawm cov platform ntug dej. Hauv qab no yog qee cov kev siv ntawm DH36 Hlau Phaj:
1. Hull qauv: DH32 daim phiaj yuav siv tau los tsim ntau hom nkoj, suav nrog cov nkoj loj, thiab lwm yam nkoj, thiab lub nkoj tus hull.
2. Ntughore Platforms: DH32 Daim Phiaj Hlau tau siv nyob rau hauv kev tsim kho roj platform roj, offshore cua lub zog platforms, ntug dej hiav txwv thiab lwm tus neeg sib txuas ua ke. Vim nws lub zog siab thiab cov khoom zoo corrosion, dh32 steel phaj tuaj yeem tiv thaiv loj loj thiab cuam tshuam rau cov chaw ua haujlwm hnyav.
3. Cov cuab yeej siv hluav taws xob tsim hluav taws xob: DH32 daim phiaj kuj tseem siv tau los tsim cov khoom siv marine tshuab, thiab siv cov nqaj hlau tseem ceeb xws li cov khoom siv-cov pas nrig ntawm cov khoom siv no.
