CCS B Shipbuilding Steel Phaj Nqe Aisi Shipbuilding Steel

CCS B shipbuilding steel phaj nqi:
Thaum lub Cuaj Hlis 2, 2024, cov ntaub ntawv tus nqi ntawm CCS B shipbuilding steel phaj hauv qee thaj tsam yog raws li hauv qab no:
Nyob rau hauv Fuzhou, tus nqi ntawm 10 hli CCS B shipbuilding phaj ntawm Shaogang yog 3940 yuan / tuj;
Hauv Ningbo, tus nqi ntawm 8 hli CCS B shipbuilding phaj ntawm Xinyu Steel yog 3700 yuan / tuj;
Hauv Tianjin, tus nqi ntawm 6 hli CCS B shipbuilding phaj ntawm Shandong Hlau thiab Hlau Rizhao yog 4230 yuan / tuj.
Nws yuav tsum tau muab sau tseg tias tus nqi ntawm CCS B shipbuilding steel daim hlau yuav raug cuam tshuam los ntawm ntau yam, xws li thickness, dav, ntev, chaw tsim tshuaj paus, kev lag luam khoom thiab kev sib raug zoo ntawm kev thov, thiab cov khoom raw cov nqi hloov pauv. Yog li ntawd, tus nqi nyob rau hauv txawv cheeb tsam, specifications, thiab lub sij hawm yuav txawv.

 

 

 

CCS B (Structural Steel for General Strength Hull Structures Grade B) yog lub nkoj tsim steel phaj ntawv pov thawj los ntawm Tuam Tshoj Classification Society. Cov hauv qab no yog qee yam ntxwv thiab cov ntaub ntawv ntsig txog CCS B shipbuilding steel:
Tshuaj muaj pes tsawg leeg:
Cov ntsiab lus carbon (C) Tsawg dua lossis sib npaug rau 0.21%;
Silicon (Si) cov ntsiab lus Tsawg dua lossis sib npaug rau 0.35%;
Manganese (Mn) cov ntsiab lus nyob nruab nrab ntawm 0.80% - 1.20%;
Phosphorus (P) cov ntsiab lus Tsawg dua lossis sib npaug rau 0.035%;
Sulfur (S) cov ntsiab lus Tsawg dua lossis sib npaug rau 0.035%.
Mechanical zog:
Cov qib steel yog qib B, thiab qhov taw tes tawm (σs) siab dua lossis sib npaug ntawm 22 MPa;
Lub zog tensile (σb) yog nruab nrab ntawm 400 MPa - 520 MPa;
Lub elongation tom qab tawg (δ) yog ntau dua los yog sib npaug li 22%;
Qhov ntsuas kub yog 0 degree .
Kev Siv: Feem ntau yog siv rau hauv kev tsim cov superstructures ntawm hiav txwv-mus ships, sterns, rudders thiab bulkheads, raws li zoo raws li lub hulls thiab shipboard vaj tse ntawm inland shipping.
Qhov zoo:
Zoo weldability: Qhov no yog ib qho tseem ceeb heev rau kev tsim kho ntawm cov qauv hull. Nws tuaj yeem ua kom ntseeg tau tias kev sib txuas ntawm cov hlau phaj yog ruaj khov thiab txhim khu kev qha, thiab xyuas kom meej tag nrho lub zog thiab nruj ntawm lub hull.
Zoo corrosion kuj: Nyob rau hauv hnyav tej yam kev mob xws li marine ib puag ncig, nws muaj peev xwm tiv taus qhov yaig ntawm dej hiav txwv thiab hiav txwv cua, thiab ua kom lub neej ntev ntawm lub nkoj.
Qhov tseeb qhov ntev: Nws tuaj yeem ua tau raws li cov kev cai nruj rau steel phaj qhov ntev hauv cov txheej txheem shipbuilding, uas yog yooj yim rau kev ua thiab sib dhos thiab txhim kho shipbuilding efficiency thiab zoo.
Cov neeg tsim khoom: Cov hlau hauv tsev uas tuaj yeem tsim CCS B nkoj daim hlau suav nrog Baosteel, Magang, WISCO, Xiangtan Hlau thiab Hlau,

Anyang Hlau thiab Hlau, Shagang, Ansteel, Nanjing Hlau thiab Hlau, Xinyu Steel, thiab lwm yam.
Thaum siv CCS B shipbuilding steel, nws yog ib qho tsim nyog yuav tau xaiv cov ntaub ntawv, txheej txheem thiab tshuaj xyuas nruj me ntsis raws li cov qauv thiab cov kev qhia tshwj xeeb los xyuas kom meej qhov zoo thiab kev nyab xeeb ntawm lub nkoj. Nyob rau tib lub sijhawm, nrog rau kev txhim kho txuas ntxiv ntawm kev tsim khoom siv nkoj thiab kev txhim kho txuas ntxiv ntawm kev ua haujlwm ntawm lub nkoj, cov kev xav tau tshiab thiab cov kev sib tw tseem tau muab tso rau pem hauv ntej rau kev ua tau zoo thiab zoo ntawm CCS B nkoj daim hlau.
