He aha ka ʻokoʻa ma waena o EN39 S235GT a me Q235?

He mau ʻano kila ʻo EN39 S235GT a me Q235 i hoʻohana ʻia no nā hana kūkulu hale.

ʻO EN39 S235GT kahi papa kila maʻamau ʻEulopa e pili ana i ka hoʻohuihui kemika a me nā waiwai mechanical o ke kila. Loaʻa iā ia ka Max. 0.2% kalapona, 1.40% manganese, 0.040% phosphorus, 0.045% sulfur, a emi ma mua o 0.020% Al. ʻO ka ikaika tensile hope loa o EN39 S235GT he 340-520 MPa.

ʻO Q235, ma ka ʻaoʻao ʻē aʻe, he papa kila maʻamau Kina. Ua like ia me ke papa kila EN maʻamau S235JR i hoʻohana nui ʻia ma ʻEulopa. ʻO ka nui o ke kalapona o ke kila Q235 he 0.14%-0.22%, ka nui o ka manganese ma lalo o 1.4%, ka nui o ka phosphorus he 0.035%, ka nui o ka sulfur he 0.04%, a me ka nui o ka silicon he 0.12%. ʻO ka ikaika tensile hope loa o Q235 he 370-500 MPa.

I ka hōʻuluʻulu manaʻo, he like nā ʻano kemika o EN39 S235GT a me Q235 akā he ʻokoʻa iki nā waiwai mechanical. ʻO ke koho ma waena o nā mea ʻelua e pili ana i ka noi kikoʻī a me nā koi o ka papahana.
