Icyapa cya WStE500

Dukurikije EN 10025-2, icyapa cya S275J2 gikoreshwa cyane cyane mubikorwa byubwubatsi n’ubuhanga bw’imashini, kontineri, tanks hamwe n’ibikoresho byerekana ibyuma nk'icyuma gifata inguni, ibyuma, H-beam, T-igice. Kuri S275J2 ibyuma bya karubone, niba abakiriya bashaka kunoza imikorere yicyuma mugihe bakoresha, injeniyeri zacu ziracyasaba ko hajyaho uburyo bwo kuvura ubushyuhe. Bitabaye ibyo, ibyuma bigomba kwipimisha ubushyuhe buke kuri -20 ° C.

DIN WStE500 isahani yicyuma, kubijyanye nimiterere yimiti, ibintu bitandukanye biri mubintu bya karubone, naho karubone ni A283Gr. d ntabwo irenze 0.27%, kandi irenze icyiciro C (≤0.24%); Kubijyanye nubukanishi, itandukaniro riri mumbaraga zingana nimbaraga zitanga umusaruro, mugihe ASTM A283 Gr.D ifite imbaraga zingana na 415-550MPa (60-80 ksi) naho ASTM A283 D ifite umusaruro wa 230MPa (33 ksi ).
