Dab tsi yog A500 grc ua los ntawm?
A500 Gr.C Cov Khoom Ntsuam Xyuas (Hloov Kho 2025)
A500 GR.C (feem ntau sau grC) yog cov khoom siv carbon hlau / duab plaub hau rau kev siv cov kab ke ntawm cov txheej txheem ASTM A500 tus qauv, nrog cov hauv qab no tseem ceeb:
1. Cov Khoom Siv Khoom Siv
Cov Qauv Ntaus: Ua raws li qhov yuav tsum tau ua ntawm Astm ATTM A500 tus qauv rau cov khaub ncaws welded / seamless cov qauv steel yeeb nkab.
Tshuaj lom neeg muaj tshuaj: ntxiv dag zog nrog cov ntsiab lus sib xyaw (piv txwv li cov ntsiab lus carbon) tsawg dua los yog sib npaug ntawm 1.35%, suav rau hauv tus account ob lub zog thiab weldability.
Cov Khoom Siv Neeg Kho Tshuab:
Tensile lub zog ntau dua los yog sib npaug rau 455 MPa, tawm kom muaj zog dua los yog sib npaug ntawm 345 Mpa (siab dua Gr.b Qib);
Elongation ntau dua los yog sib npaug rau 18%, thiab kev nruj me ntsis nyob rau hauv ib puag ncig kub tsawg.
2. Cov txheej txheem thiab daim ntawv
Cov txheej txheem tsim khoom: tsim los ntawm cov txheej txheem vuam zoo (ERW) lossis yuav tsum tau ua ib txwm muaj tom qab txias kev ntxhov siab.
Daim Ntawv Daim: Xwmfab / duab plaub fab hla kev, cov phab ntsa tuab ntawm 2-20 mm, haum rau cov kabmob thauj khoom thiab cov qauv kev txhawb nqa.
3. Raug ntawv thov cov xwm txheej
Architecture: steel thav ntawv rau cov tsev siab siab, Seismic bracing systems;
Neeg kho tshuab Engineering: Cov cuab yeej hnyav pob txha taub hau, tsheb chassis;
Marine chaw: Nkoj Lawj Support, Tubrog Platform Truss.
4. Kev sib piv nrog lwm qib
Piv nrog A500 Gr.B: Gr.C muaj lub zog siab dua / tawm los ntawm 400 MPA rau Gr.B) thiab haum rau cov xwm txheej siab dua;
Piv nrog A513 txheeb xyuas ntawm Machinancability, thaum A500 Gr.C muaj cov txheej txheem muaj zog raws li nws lub zog zog.
Nco tseg: Thaum xaiv cov ntaub ntawv, nws yog qhov tsim nyog los tshawb xyuas cov ntaub ntawv pov thawj (MTC) muab los ntawm tus neeg xa khoom kom paub meej tias cov khoom siv cov khoom siv neeg siv hluav taws xob tau nce rau cov qauv.
