ASTM A283 Carbon steel ntawv

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 qhov qhib-hearth, 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.
