WStE500 pā kila

Wahi a EN 10025-2, hoʻohana nui ʻia ka pā kila S275J2 i ka ʻoihana hana a me ka ʻenekinia mechanical, nā ipu, nā pahu a me nā kiʻi kila i ʻōwili ʻia e like me ke kila kihi, ke kila kila, H-beam, T-section. No ke kila kalapona S275J2, inā makemake nā mea kūʻai aku e hoʻomaikaʻi i ka hana o ke kila i ka wā e hoʻohana ai, ʻōlelo mau kā mākou mea ʻenehana i ka hoʻomaʻamaʻa ʻana i ka wela. Inā ʻaʻole, pono ke kila i kahi hoʻokolohua haʻahaʻa haʻahaʻa haʻahaʻa ma -20 ° C.

ʻO ka pā kila DIN WStE500, e like me ka mea hoʻohui kemika, ʻo ka ʻokoʻa ʻokoʻa ka mea nui i loko o ka ʻona kalapona, ʻoiai ʻo ka ʻona kalapona ʻo A283Gr. ʻaʻole ʻoi aku ka d ma mua o 0.27%, a ʻoi aku ka kiʻekiʻe ma mua o ka papa C (≤0.24%); No nā waiwai mechanical, aia ka ʻokoʻa i ka ikaika tensile a me ka ikaika hua, ʻoiai ʻo ASTM A283 Gr.D ka ikaika tensile o 415-550MPa (60-80 ksi) a ʻo ka ASTM A283 D ka helu he 230MPa (33 ksi). ).
