1. General zog steel rau hull qauv
Lub zog dav dav hlau rau cov qauv hull tau muab faib ua plaub qib: A, B, D, thiab E. Lub zog tawm los (tsis pub tsawg dua 235N / mm ^ 2) thiab lub zog tensile (400 ~ 520N / mm ^ 2) ntawm plaub qib no ntawm steel yog tib yam. , nws tsuas yog qhov cuam tshuam lub zog sib txawv ntawm qhov sib txawv ntawm qhov kub thiab txias;
High-strength hull qauv steel yog muab faib ua qib zog raws li nws qhov tsawg kawg nkaus yield zog, thiab txhua qib zog yog muab faib ua A, D, E, thiab F4 qib raws li nws tej yam toughness.
Lub zog tawm ntawm A32, D32, E32 thiab F32 tsis tsawg dua 315N / mm^2, thiab lub zog tensile yog 440 ~ 570N / mm^2. A, D, E thiab F feem qhia tias lawv tuaj yeem siv tau ntawm 0 degree , -20 degree , Impact toughness uas tuaj yeem ua tiav ntawm -40 degree thiab -60 degree ;
Lub zog tawm ntawm A36, D36, E36 thiab F36 tsis tsawg dua 355N / mm^2, thiab lub zog tensile yog 490 ~ 620N / mm^2. A, D, E thiab F feem qhia tias lawv tuaj yeem siv tau ntawm 0 degree , -20 degree , Impact toughness uas tuaj yeem ua tiav ntawm -40 degree thiab -60 degree ;
Lub zog tawm ntawm A40, D40, E40 thiab F40 tsis tsawg dua 390N / mm^2, thiab lub zog tensile yog 510 ~ 660N / mm^2. A, D, E thiab F feem qhia tias lawv tuaj yeem siv tau ntawm 0 degree , -20 degree , Qhov cuam tshuam toughness tuaj yeem ua tiav ntawm -40 degree thiab -60 degree .
ntxiv,
High-strength quenched thiab tempered steel rau welded lug: A420, D420, E420, F420; A460, D460, E460, F460; A500, D500, E500, F500; A550, D550, E550, F550; A620, D620, E620, F620; A690, D690, E690, F690;
Hlau rau boilers thiab siab hlab ntsha: 360A, 360B; 410A, 410B; 460A, 460B; 490A, 490B; 1Cr0.5Mo, 2.25Cr1Mo
Hlau rau cov qauv siv tshuab: Feem ntau, cov khoom siv hlau hais saum toj no tuaj yeem siv tau;
Tsawg kub toughness steel: {{0}}.5NiA, 0.5NiB, 1.5Ni, 3.5Ni, 5Ni, 9Ni;
Austenitic stainless hlau: {{0}}Cr18Ni10, 00Cr18Ni10N, 00Cr17Ni14Mo2, 00Cr17Ni13Mo2N, 00Cr19Ni13Mo3, {{18}3Ni19} 0Cr18Ni11Nb;
Duplex stainless hlau: 00Cr22Ni5Mo3N, 00Cr25Ni6Mo3Cu, 00Cr25Ni7Mo4N3.
Composite steel daim hlau: haum rau ntim thiab cargo tanks ntawm cov neeg nqa khoom tshuaj;
Z-kev taw qhia steel: Nws yog cov khoom siv hlau uas tau txais kev kho tshwj xeeb (xws li kev kho calcium, nqus degassing, argon nplawm, thiab lwm yam) thiab kev kho cua sov tsim nyog raws li qib ntawm cov qauv hlau (hu ua niam txiv steel).
