S235 JRyog ib qho nrov qis - carbon structural steel (tsis yog-alloy) dav siv thoob plaws xyoo 2025 kev tsim kho thiab kev tsim khoom vim nws cov weldability zoo, machinability, thiab nqi-effectiveness. Nws lub npe qhia txog qhov tsawg kawg nkaus tawm lub zog ntawm 235 MPa thiab "JR" qhia tias nws tau dhau qhov kev ntsuam xyuas Charpy ntawm chav tsev kub (20 degree).
Cov ntawv thov tseem ceeb ntawm S235JR steel suav nrog:
1. Tsev thiab Civil Engineering
S235JR yog ib qho "baseline" steel qauv rau tej yaam num uas muaj zog txaus txaus.
Cov ntsiab lus ntawm cov qauv: Siv dav rau kab teeb (I-beams, H-beams), kab, trusses, thiab girders hauv cov tsev nyob thiab cov tsev lag luam.
Infrastructure: Fabrication ntawm cov choj, tunnels, tuav cov phab ntsa, thiab kev txhawb nqa rau txoj kev thiab railways.
Utility Structures: Cheebtsam rau kis tau tus yees, mounting systems rau lub zog tauj dua tshiab (hnub ci / cua), thiab telecommunication yees.
2. Machinery thiab Industrial Equipment
Nws cov machinability siab ua rau nws zoo tagnrho rau kev tsim cov khoom tsis yog- qhov tseem ceeb.
Mechanical Parts: Siv rau brackets, kev txhawb nqa, thav duab, gears, pulleys, thiab shafts nyob rau hauv nruab nrab -sized industrial machinery.
Agricultural Equipment: Tsim cov khoom siv rau cov qoob loo, tsheb laij teb, thiab lwm yam khoom siv ua liaj ua teb.
Khoom hnyav: Cov khoom siv rau cranes, excavators, thiab nqa khoom.
3. Kev thauj mus los thiab Marine
Automotive: Chassis Cheebtsam, trailer ncej, tsheb lub cev, thiab ntau yam brackets uas siab -kev ua tau zoo alloy tsis tas yuav tsum tau.
Shipbuilding: Siv rau hauv cov qauv hull thiab cov khoom txhawb nqa sab hauv rau cov nkoj thiab cov nkoj uas xav tau kev ruaj khov nyob rau hauv ib puag ncig marine.
Railway: Kev tsim kho cov kev tsheb ciav hlau (rau qee cov kab thib ob), chaw nres tsheb, thiab tsheb sib txuas.
4. Kev lag luam tshwj xeeb
Roj thiab Roj: Kev tsim cov chaw tawm sab nrauv, cov tso tsheb hlau luam, thiab qis - cov kav dej siab.
Kev Tiv Thaiv: Cov qauv tsim ntawm cov tsev tub rog, cov neeg ua haujlwm armored, thiab cov nkoj tub rog.
Nroog Infrastructure: Feem ntau hauv cov rooj tog zaum hauv pej xeem xws li cov rooj zaum, teeb ncej, tes tuav, thiab cov khoom siv hauv chaw ua si.

S235 steel siv rau dab tsi?
Nws cov lus "JR" qhia tias nws qhov kev cuam tshuam tsawg kawg yog 27 joules thiab nws tau dhau los ua qhov kev ntsuam xyuas ntawm 20 degree. S235JR nyiam siv nyob rau hauv cov tsev tsim, roj thiab roj platforms, thiab cov khoom siv rau kev thauj mus los
Daim ntawv thov ntawm S355JR yog dab tsi?
Structureal unalloyed steel S355JR muaj ntau yam kev siv hauv kev tsim kho, metallurgy, hnyav thiab thauj engineering, tshuab cuab yeej, hluav taws xob engineering thiab kev lag luam choj. Ntau yam profiles thiab cov qauv hlau, qhov chaw thiab cov khoom siv hauv av thiab hauv av yog tsim los ntawm steel S355JR.
