1. Hlau rau dav dav lub zog 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) ntawm plaub qib ntawm cov hlau no yog tib yam li lub zog tensile (400～ 520 N/mm^2)., tab sis lub zog cuam tshuam ntawm qhov kub thiab txias sib txawv;
High-strength hull structural 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, 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.Kev cuam tshuam toughness tuaj yeem ua tiav ntawm -40 °, -60 °;
Lub zog tawm ntawm A36, D36, E36 thiab F36 tsis tsawg dua 355N / mm^2, thiab lub zog tensile yog 490 ~ 620N / mm^2.Kev cuam tshuam toughness tuaj yeem ua tiav ntawm -40 °, -60 °;
Lub zog tawm ntawm A40, D40, E40, thiab F40 tsis tsawg dua 390N / mm^2, thiab lub zog tensile yog 510 ~ 660N / mm^2.Qhov cuam tshuam toughness tuaj yeem ua tiav ntawm -40 ° thiab -60 °.
ib yam li ntawd,
High-strength quenched thiab tempered steel rau welded qauv: 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 hlau saum toj no tuaj yeem siv tau;
Tsawg kub toughness steel: 0.5NiA, 0.5NiB, 1.5Ni, 3.5Ni, 5Ni, 9Ni;
Austenitic stainless hlau: 00Cr18Ni10, 00Cr18Ni10N, 00Cr17Ni14Mo2, 00Cr17Ni13Mo2N, 00Cr19Ni13Mo3, 00Cr19Ni13Mo3N, 0Cr18Ni11Nb;
Duplex stainless hlau: 00Cr22Ni5Mo3N, 00Cr25Ni6Mo3Cu, 00Cr25Ni7Mo4N3.
Clad steel phaj: haum rau ntim thiab cargo tanks ntawm cov neeg nqa khoom tshuaj;
Z-kev taw qhia steel: Nws yog cov 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).
