1.Dab tsi yog qhov txawv ntawm Sheet & Plate Steel?

Hlau yog ib qho hlau hlau uas tau txhim kho cov tshuaj lom neeg thiab lub cev. Cov hlau feem ntau pom muaj alloyed nrog ntawm 0.2 feem pua thiab 2.15 feem pua ntawm cov pa roj carbon monoxide, tab sis qee cov hlau tuaj yeem pom muaj alloyed nrog lwm cov ntaub ntawv xws li tungsten, chromium, vanadium thiab manganese. Hlau tau siv txij li thaum ub, tab sis nws tau tsim tsis muaj txiaj ntsig thiab kim kom txog rau thaum nruab nrab xyoo pua 19th, thaum cov txheej txheem Bessemer tau tsim. Txij thaum ntawd los, cov hlau tau tsim ntau ntau yam, nrog rau cov ntawv hlau, phaj hlau thiab cov ntawv hlau.

2.2304 Duplex |UNS-S32304 2304 Duplex |UNS-S32304 stainless yog ib tug lean duplex stainless hlau uas muaj ib tug microstructure muaj xws li austenite thiab ferrite theem. Qhov no duplex microstructure thiab cov tshuaj muaj pes tsawg leeg ntawm 2304 Duplex stainless cov txiaj ntsig yog kev sib xyaw ua ke zoo heev ntawm lub zog thiab kev tiv thaiv corrosion. 2304 Duplex stainless muaj qhov zoo tiv thaiv corrosion nyob rau hauv ntau qhov chaw acid, chloride stress corrosion cracking, pitting thiab crevice corrosion.

Daim ntawv thov Rebar yog thawj daim ntawv thov rau 2304 Duplex stainless. Cov ntawv thov tshwj xeeb rebar tau suav nrog cov choj decks, thaiv thaiv thiab tuav cov phab ntsa, anchoring systems thiab dowels, chemical plant infrastructure, coastal piers and wharves, choj parapets, sidewalks thiab choj pilings. Lwm daim ntawv thov rau 2304 Duplex stainless suav nrog choj khi hlau. Lub zog siab muaj peev xwm ntawm qhov tsawg kawg nkaus lub zog ntawm 75 ksi (518 MPa) rau 2304 Duplex stainless rebar yog ib qho txiaj ntsig kev lag luam ntxiv.

Corrosion Resistance 2304 Duplex|UNS-S32304 stainless muaj zoo intergranular corrosion kuj nyob rau hauv lub as-annealed thiab as-welded tej yam kev mob vim nws cov ntsiab lus carbon tsawg. Qee qhov kev tawm tsam intergranular tuaj yeem tshwm sim nyob rau hauv qhov kub dov untouched mob. Rau qhov zoo tshaj plaws corrosion kuj, qhov chaw yuav tsum tsis muaj nplai, lubricants, txawv teb chaws hais, thiab coatings thov rau kos duab thiab nqe lus. Tom qab fabrication ntawm qhov chaw tu thiab / los yog passivation yuav tsum xav txog.
