S355J2W steel txhais tau hais tias: S txhais tau tias cov qauv hlau, 355 yog lub zog tawm ntawm 355MPa, J2 yuav tsum muaj -20℃cuam tshuam, thiab tsab ntawv W qhia tias S355J2W steel muaj peev xwm tiv taus atmospheric corrosion.

S355J2WP steel txhais tau tias: S355J2WP yog cov phosphorus corrosion resistant structural steel siab. S txhais tau hais tias cov qauv hlau, 355 yog lub zog tawm ntawm 355MPa, J2 xav tau -20℃cuam tshuam, tsab ntawv W qhia tias cov hlau muaj peev xwm tiv taus atmospheric corrosion, thiab P yog cov tshuaj phosphorus.

Taw qhia rau S355J2W thiab S355J2WP steel phaj:
S355J2W belongs rau cov hlau zoo. S355J2W steel phaj yog kev txhim kho atmospheric corrosion resistant structural steel. S355J2W steel phaj yog dav siv nyob rau hauv siab - ceev railway bogies, vuam, bolting thiab riveting qhov chaw. S355J2W txhim khu lub atmospheric corrosion kuj muaj peev xwm siv ntawm ambient kub. Qee cov ntsiab lus alloy tshwj xeeb, xws li P, Cu, Cr, Ni, Mo, tau ntxiv kom ua tiav cov kev tiv thaiv corrosion, tsim cov txheej txheem oxide tiv thaiv ntawm cov hlau nto nyob rau hauv ntau yam kev nyab xeeb.

Nws tau muab faib ua S235J0W, S235J2W, S355J0WP, S355J2WP, S355J0W, S355J2W thiab S355K2W. Thaum lub phaj hlau raug cim nrog "+ N lossis + AR", cov khoom raug yuam kom teev thiab xa raws li cov xwm txheej ntawm + N lossis + AR. Lub cim "+ N lossis + AR" yuav muab ntxiv rau lub npe steel thiab tus lej hlau. Piv txwv li: thaum lub zog tsawg kawg nkaus tawm los yog 355MPa MPa nyob rau hauv ib puag ncig, qhov tsawg kawg nkaus tus nqi ntawm 0 cuam tshuam lub zog yog 27J Joule (J0) thiab kev txhim kho atmospheric corrosion kuj (W) raws li tus qauv dov xa khoom (S): steel phaj EN10025-5-S355J0W + N; Los yog steel phaj EN10025-5-1.8959+N (los yog + AR).
