Dab tsi yog A500 GRD tau ua los ntawm?
A500 Gr.D (lossis sau GRD) yog lub zog siab tshaj plaws ntawm cov txheej txheem roj carbon monomium / duab plaub fab, tsim kev pabcuam hnyav thiab cov kev pabcuam hauv qab no:
1. Cov Khoom Siv Khoom Siv
Tus qauv cim: Ua tau raws li cov kev xav tau ntawm Astim A500 Qib D rau cov txheej txheem Welded / Seamless Cov Qauv Siv Hlau Hlau.
Tshuaj lom neeg muaj feem: raws li cov pa roj carbon steel nrog cov ntsiab lus carbon ntau dua lossis sib npaug nrog 1.40%, nrog cov ntsiab lus sib luag los txhim kho cov khoom ua haujlwm tag nrho.
Cov Khoom Siv Neeg Kho Tshuab:
Tensile lub zog ntau dua los yog sib luag rau 483 MPa, tawm kom muaj zog dua los yog sib npaug ntawm 345 siab dua li Gr.B thiab Gr.c Qib);
Elongation ntau dua los yog sib npaug rau 18%, sib txuas siab siab thiab tawv.
2. Technology thiab daim ntawv foos
Cov txheej txheem tsim khoom: High-zaus vuam (ERW) lossis seamless ntau lawm, yuav tsum tau ua kom tshem tawm cov kev ntxhov siab;
Cov Specifications yog: Square / Rectangular seem sab seem 20-500 mm, phab ntsa thickness {} 6-12 meters.
3. Thaj chaw ntawm daim ntawv thov
Tus qauv tsim tsev: Hlau thav duab ntawm Super High-Ris Kev Txhawb Zog, Loj-Spain Choj choj;
Cov Machinery: Crane Jib, Khoom Siv Mining Thauj Khoom-Cov kabmob;
Marine Engineering: Sib sib zog-Hiav Txwv Platform Txheej Txheem Txheej Txheem Txheej Txheem, Lub Siab-Muaj Zog Txuas Rau Cov Nkoj.
4. Kev sib piv nrog lwm qib
Kev sib piv ntawm Gr.b / Gr.d muaj ntau dua tensile lub zog (ntau dua los yog sib npaug rau ntawm 455 MPa) rau cov kev thauj khoom heev;
Kev sib piv ntawm Alloy Steel: Gr.D yog tsim cov roj carbon hlau, uas tsawg dua li cov hlau siab ntau dua li cov hlau loj, tab sis nws yuav tsum tau sau tseg tias cov corrosion tsis muaj zog dua.
5. Cov Ntaub Ntawv Ua Lag Luam (2025 Siv)
Qhov nqi ntau: Hais txog rmb 4300-5330 / tonne (raug rau cov lus qhia tshwj xeeb, txheej txheem thiab kev thov kom muaj);
Cov lus qhia rau kev xaiv: nws yog qhov tsim nyog los xyuas cov ntawv pov thawj khoom (MTC) muab los ntawm tus neeg xa khoom kom paub meej tias cov khoom siv tshuab thiab tshuaj lom neeg muaj pes tsawg leej txheem.
NCO TSEG: Yog tias kev tsim kho kom haum, nws raug pom zoo rau galvanize lossis lub tsho loj Gr.d steel kav rau kev kho mob corrosion corrosion
