S235JR steel qib yog dab tsi?
S235JR yog tus qauv nrov European (EN 10025-2) tsis yog- alloy structural steel paub rau nws qhov zoo weldability, formability, thiab nqi-effectiveness, nrog 'S' rau steel, '235' rau nws qhov tsawg kawg nkaus yield zog (235 MPa), thiab 'JR' nyob rau hauv qhov ntsuas kub ntawm 20 ℃ ). Nws yog dav siv nyob rau hauv kev tsim kho, lub tsev thav duab, automotive qhov chaw, thiab machinery rau nws versatility, tab sis nws yuav tsum tau tiv thaiv coatings raws li nws tsis inherently xeb-resistant. Qhov sib npaug tseem ceeb suav nrog ASTM A36 thiab JIS SS400.
Cov yam ntxwv tseem ceeb
Yield Strength: Yam tsawg kawg 235 MPa (rau thickness> 16mm).
Tensile zog: 360-510 MPa.
Impact Test: 27 Joules ntawm 20℃(JR).
Weldability: Zoo heev vim muaj cov ntsiab lus carbon tsawg, ua rau nws yooj yim rau vuam.
Corrosion Resistance: Tsis yog qhov muaj zog corrosion-resistant; xav tau kev pleev xim lossis galvanizing rau sab nraum zoov siv.
Cov ntawv thov siv
Kev tsim kho: Lub tsev thav duab, kab teeb, kab, kab ru tsev, scaffolding.
Mechanical Engineering: Tshuab qhov chaw, khoom siv, tsheb thauj khoom, excavators.
Automotive: Chassis, thav duab, cov qauv kev nyab xeeb.
Infrastructure: choj, kis tau tus yees, offshore structures.
Qib sib npaug
ASTM A36, A283 Qib C.
Qauv: SS400.
Qauv TSIS MUAJ: ST37-2.
Vim Li Cas Nws Thiaj Nrov
Versatility: Haum rau ntau yam ntawm cov qauv thiab cov khoom siv kho tshuab.
Affordability: Nqi -zoo piv rau siab - steels ua tau zoo.
Processability: Zoo machinability thiab formability.
Tag nrho cov specification thiab cov ntsiab lus muaj nyob rau ntawm kev thov. Cov ntaub ntawv saum toj no yog muab rau kev taw qhia nkaus xwb. Rau kev tsim tshwj xeeb thov hu rau peb cov neeg ua haujlwm muag khoom.
