Qhov sib txawv ntawm ABS AH40 thiab CCS AH40

ABS AH40 thiab CCS AH40 yog ob qho tib si siab - lub zog shipbuilding steel daim hlau tsim los rau kev tsim lub nkoj thiab cov qauv hauv hiav txwv. Lawv tau ntawv pov thawj los ntawm ob lub koom haum kev faib khoom loj-ABS (American Bureau of Shipping) thiab CCS (China Classification Society)-tab sis muaj kev sib npaug ntawm cov khoom siv tshuab thiab tshuaj lom neeg muaj pes tsawg leeg.

ABS Qib AH40 tau ntawv pov thawj los ntawm American Bureau of Shipping thiab txhais tau tias yog lub siab - lub zog steel rau kev tsim khoom nkoj thiab kev siv hluav taws xob sab nrauv. Nws muaj qhov tsawg kawg nkaus lub zog ntawm 390 MPa thiab lub zog tensile ntau ntawm 510-660 MPa . Qhov kev xaiv "A" qhia txog kev cuam tshuam ntawm 0 degree, nrog qhov tsawg kawg nkaus Charpy V-Notch cuam tshuam lub zog ntawm 41J (ntev) rau thicknesses txog 50mm. Cov ntawv thov xws li cov qauv hull, offshore drilling platforms, thawv ships, bulk carriers, thiab marine khoom.

CCS Qib AH40 tau ntawv pov thawj los ntawm Tuam Tshoj Classification Society thiab ua haujlwm ncaj qha rau ABS AH40 hauv Suav kev faib tawm. Nws qhia cov cuab yeej cuab tam zoo ib yam: qhov tsawg kawg nkaus lub zog ntawm 390 MPa, tensile zog ntawm 510-660 MPa, thiab qhov tsawg kawg nkaus elongation ntawm 20%. Zoo li nws cov khoom siv ABS, CCS AH40 yuav tsum muaj kev ntsuas kev cuam tshuam ntawm 0℃nrog yam tsawg kawg nkaus 41J. Cov tshuaj muaj pes tsawg leeg yog sib piv, nrog siab tshaj carbon ntawm 0.18%, manganese ntawm 0.90-1.60%, thiab microalloying ntsiab xws li Nb thiab V rau grain refinement.

Qhov txawv tseem ceeb:
Qhov tseem ceeb ntawm qhov sib txawv ntawm ob qib no yog nyob rau hauv lawv daim ntawv pov thawj txoj cai thiab cov kev tswj xyuas zoo. ABS AH40 ua raws li American Bureau of Shipping cov cai thiab tau lees paub thoob ntiaj teb, tshwj xeeb tshaj yog nyob rau hauv cov haujlwm uas yuav tsum tau muaj ntawv pov thawj ABS. CCS AH40 ua raws li Tuam Tshoj Classification Society cov cai thiab feem ntau tau teev tseg rau cov nkoj tsim nyob rau hauv Suav shipyards los yog rau tej yaam num nyob rau hauv Suav faib. Los ntawm kev pom kev, cov hlau no suav hais tias hloov pauv tau, thiab ntau lub tuam txhab tuaj yeem tsim cov ntawv pov thawj los ntawm ob lub zej zog ib txhij.
