Lo lus pib nrog S yog carbon steel structural steel, thiab 355 uas nram qab no txhais tau hais tias qhov tsawg kawg nkaus yield zog ntawm chav tsev kub yog 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 thiab tsis tas txhais hais tias normalizing. Nws tsuas yog ib txoj hauv kev rau npe cov qib steel hauv tus qauv.
S355J2+N steel phaj siv tus qauv: EN10025. Cov qib zoo sib xws: S235JR+N S235J0+N S235J2+N S275JR+N S275J0+N S275J2+N S275N S275NL S355JR+N S355J{20} 2+N S355K2 S355N+N S355NL
S355J2+N steel phaj muaj lub zog tensile zoo heev thiab cuam tshuam tsis kam, thiab S355J2+N steel phaj muaj kev ua haujlwm zoo thiab kev ua haujlwm vuam.
S355J2 steel phaj muaj zoo toughness thiab vuam kev ua tau zoo, thiab yog tsim rau machinery thiab khoom tsim lag luam xws li ships, steel qauv, metallurgy, mining, engineering machinery, choj machinery, fais fab chaw nres tsheb khoom, nqa thiab tsheb thauj mus los machinery, machinery manufacturing thiab lwm yam dej num. uas dais siab dua.
