ASTM A283 Carbon Steel Phaj
Qib: ABCD
Thickness: los ntawm 6mm mus rau 150mm
Dav: los ntawm 1,500mm txog 4,100mm
Ntev: los ntawm 6,000mm txog 20,000mm
ASTM A36, ASTM A572, ASTM A656, JIS G3101 SS400, EN10025-2, DIN 17100, DIN 17102, GB / T700, GB / T1591
ASTM A283 phaj steel nta qis thiab nruab nrab tensile lub zog carbon steel phaj ntawm cov qauv zoo. Nws muaj plaub qhov sib txawv, txhua tus sawv cev ua cov khoom sib cais. Cov khoom vaj khoom tsev seem hauv qab no qhia tau hais tias muaj ntau qhov sib txawv ntawm txhua qhov sib txawv.
Qhov kev qhia tshwj xeeb no suav nrog plaub qib ntawm carbon steel daim hlau ntawm cov qauv zoo rau kev siv dav dav. Cov qauv hlau yuav tsum tau yaj ua tiav los ntawm qhib -heart, yooj yim- oxygen, lossis hluav taws xob rauv taws. Thaum tshav kub kub thiab cov khoom lag luam tsom xam yuav tsum tau ua nyob rau hauv cov ntaub ntawv hlau yuav tsum ua raws li cov tshuaj muaj pes tsawg leeg ntawm carbon, manganese, phosphorus, sulfur, silicon, thiab tooj liab. Cov qauv hlau kuj tseem yuav raug kuaj tensile thiab yuav tsum ua raws li qhov xav tau ntawm lub zog tensile, qhov taw tes tawm, thiab elongation.
A283 steel phaj yog qis-rau- nruab nrab tensile lub zog carbon steel siv rau cov qauv siv dav dav, tshwj xeeb tshaj yog nyob rau hauv lub tsev cia tso tsheb hlau luam, qis- cov hlab ntsha siab, txuas hniav, thiab lwm yam khoom siv dav dav uas yuav tsum muaj qhov zoo weldability thiab formability, standardized los ntawm ASTM. Nws los hauv qib (A, B, C, D) nrog cov qib sib txawv ntawm lub zog, nrog Qib C yog ib qho, zoo ib yam li cov hlau me me xws li ASTM A36, thiab muab cov khoom zoo rau kev tsim kho.
