S355J2W yog kev ua raws li European tus qauv EN10025 tus qauv tsim cov huab cua hlau, nws cov tuab tuab ntawm tsawg dua 100 hli, xa hauv lub xeev kub dov, nrog kev qaug zog thiab tsis kam rau atmospheric corrosion.
S355J2W qib: "S": qhia tias cov qauv hlau; "355" yield zog ntawm 355, qhia nyob rau hauv units ntawm MPa; "J2": qhov cuam tshuam ua haujlwm theem, - 20 degree cuam tshuam kev ua haujlwm tus nqi ntawm 27J "W": qhia tias cov hlau phaj huab cua.
S355J2W belongs rau cov nplua nplej hlau, S3552W yog ib qho kev txhim kho atmospheric corrosion resistant structural steel, S355J2W yog siv nyob rau hauv ntau qhov ntau rau kev kub ceev rail bogies, welded, bolted thiab riveted Cheebtsam, S355J2W txhim khu kev tiv thaiv atmospheric corrosion, thov mus rau atmospheric corrosion. kom ua tiav cov khoom tiv thaiv corrosion thiab qhov sib ntxiv ntawm qee cov ntsiab lus alloying, xws li: P, Cu, Cr, Ni, Mo, thiab lwm yam,. Nyob rau hauv ntau yam climatic tej yam kev mob nyob rau hauv cov hlau nto los tsim ib tug tiv thaiv oxide txheej.
