S355 J2+N yog European standard low alloy, S yog carbon steel structural steel, thiab 355 qab nws txhais tau hais tias lub zog tawm los ntawm chav tsev kub tsis tsawg dua 355Mpa. J2 xav tau -20 degree cuam tshuam. Raws li rau lub + N qab nws, nws txhais tau hais tias sib npaug rau normalizing dov los yog normalizing, thiab nws tsis txhais hais tias normalizing yog tsim nyog. Nws tsuas yog ib txoj hauv kev rau npe tus lej steel hauv tus qauv.
