Peb lub hom phiaj los ua tus thawj coj hauv kev lag luam hauv cov ntsiab lus ntawm cov khoom lag luam zoo, thev naus laus zis, thiab kev pabcuam cov neeg siv khoom, ua kom peb txoj kev loj hlob thiab kev vam meej hauv lub ntiaj teb no.
Dab tsi yog qhov txawv ntawm A36 thiab ABS qib A Marine Steel Phaj?
A36 thiab ABS Qib A yog ob hom steel qib uas feem ntau siv rau ntau yam kev siv. Nov yog qhov sib txawv tseem ceeb ntawm A36 thiab ABS Qib A:
Cov qauv thiab cov koom haum:
A36: A36 steel yog tus qauv carbon structural steel qib tsim los ntawm ASTM International (ASTM A36 / A36M).
ABS Qib A: ABS Qib A yog marine - qib steel qib tswj los ntawm American Bureau of Shipping (ABS) rau kev siv hauv nkoj tsim.
Tshuaj muaj pes tsawg leeg:
A36: A36 steel feem ntau muaj cov pa roj carbon ntau dua (0.25-0.29%) piv rau ABS Qib A. Nws kuj suav nrog cov khoom me me xws li manganese, phosphorus, sulfur, thiab silicon.
ABS Qib A: ABS Qib A steel feem ntau muaj cov hlau uas muaj cov qib carbon (max 0.23%), manganese, phosphorus, sulfur, silicon, thiab tooj liab.
Lub zog thiab Mechanical Properties:
A36: A36 steel muaj qhov tsawg kawg nkaus lub zog ntawm 36,000 psi (250 MPa) thiab lub zog tensile ntawm 58,000-80,000 psi (400-550 MPa). Nws muaj qhov zoo ductility thiab tuaj yeem siv rau hauv ntau yam kev siv.
ABS Qib A: ABS Qib A steel muaj qhov tsawg kawg nkaus lub zog ntawm 34,000 psi (235 MPa) thiab lub zog tensile ntawm 58,000-75,500 psi (400-520 MPa). Nws cov khoom siv kho tshuab yog tshwj xeeb rau kev siv hauv nkoj tsim thiab marine cov qauv.
Daim ntawv pov thawj thiab daim ntawv thov:
A36: A36 steel tsis yog tshwj xeeb rau kev lag luam lossis daim ntawv thov. Nws yog siv dav hauv kev tsim kho, tsim khoom, thiab kev tsim vaj tsev.
ABS Qib A: ABS Qib A hlau tau ntawv pov thawj los ntawm American Bureau of Shipping thiab feem ntau yog siv hauv kev lag luam nkoj tsim los tsim cov hulls thiab lwm cov qauv hauv hiav txwv.
Impact Testing:
A36: A36 steel tsis xav tau kev kuaj xyuas raws li nws tsis yog feem ntau siv rau hauv cov ntawv thov uas cuam tshuam tsis zoo yog qhov tseem ceeb.
ABS Qib A: ABS Qib A hlau tau dhau los ua qhov kev ntsuam xyuas kom ntseeg tau tias nws tsim nyog rau kev tsim nkoj, qhov muaj peev xwm tiv taus qhov cuam tshuam yog qhov tseem ceeb.
Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias cov no yog qhov sib txawv ntawm A36 thiab ABS Qib A, thiab cov kev cai tshwj xeeb yuav txawv nyob ntawm qhov project, cov qauv kev lag luam, thiab cov kev cai. Thaum xaiv cov qib steel tsim nyog, kev sab laj nrog engineers lossis ua raws li cov lus qhia tshwj xeeb muab los ntawm cov tub ceev xwm muaj feem cuam tshuam.
