FH36 Shipbuilding Steel Phaj 2 hli

Cov kev ua haujlwm tshwj xeeb yog raws li hauv qab no:

- Cov tshuaj muaj pes tsawg leeg: Cov ntsiab lus carbon (C) tsawg dua lossis sib npaug rau 0.16%, cov ntsiab lus silicon (Si) tsawg dua lossis sib npaug rau 0.5%, manganese (Mn ) cov ntsiab lus nyob ntawm 0.90 mus rau 1.60%, cov ntsiab lus phosphorus (P) tsawg dua lossis sib npaug 0. cov ntsiab lus tooj liab (Cu) tsawg dua lossis sib npaug rau 0.35%, cov ntsiab lus chromium (Cr) tsawg dua lossis sib npaug rau 0.020 %, cov nickel (Ni) cov ntsiab lus tsawg dua lossis sib npaug rau 0.80%, niobium (Nb) cov ntsiab lus nyob ntawm 0.02 txog 0.05%, vanadium (V) cov ntsiab lus nyob ntawm 0.05 txog 0.10%, titanium (Ti Cov ntsiab lus tsawg dua lossis sib npaug rau 0.02%, cov ntsiab lus molybdenum (Mo) tsawg dua lossis sib npaug 0.08%, cov ntsiab lus nitrogen (N) yog 0.009%, thiab cov kua qaub-soluble aluminium (Als) cov ntsiab lus ntau dua lossis sib npaug li 0.015%.
- Mechanical zog: Lub zog tawm los (ReH) yog ntau dua lossis sib npaug ntawm 355 MPa, lub zog tensile (Rm) yog li ntawm 490 txog 630 MPa, thiab elongation tom qab tawg (A5) yog ntau dua lossis sib npaug li 21%. Ntawm qhov ntsuas qhov ntsuas kub ntawm -60 degree, qhov cuam tshuam nqus zog (KV2 / J) sib txawv rau qhov sib txawv thicknesses. Thaum lub thickness tsis ntau tshaj 50 hli, lub longitudinal cuam tshuam nqus zog yog ntau tshaj los yog sib npaug rau 34J thiab transverse yog ntau tshaj los yog sib npaug rau 24J. Thaum lub thickness yog ntau tshaj 50 hli thiab tsis ntau tshaj 70 hli, lub longitudinal yog ntau tshaj los yog sib npaug rau 41J thiab lub transverse yog ntau tshaj los yog sib npaug rau 27J. Thaum lub thickness yog ntau tshaj 70 hli thiab tsis ntau tshaj 100 hli, lub longitudinal yog ntau tshaj los yog sib npaug rau 50J thiab lub transverse yog ntau tshaj los yog sib npaug rau 34J.

Tsis tas li ntawd, tus qauv siv rau FH36 nkoj phaj yog GB712-2000, thiab nws feem ntau xa hauv lub xeev zoo li qub. Nws tau raug lees paub los ntawm cuaj pawg neeg sib cais thiab tuaj yeem siv rau hauv nkoj tsim, nkoj txhawb nqa tshuab, hull plhaub tsim, cov khoom siv hauv nkoj, kev tu nkoj, cov khoom siv nqa dej hiav txwv, cov tshuab lawj, nrog rau cov roj av offshore, cov qauv hauv hiav txwv, thiab lwm yam. .
