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

ʻO EN39 S235GT a me Q235 nā māka kila ʻelua i hoʻohana ʻia no ke kūkulu ʻana.

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

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

I ka hōʻuluʻulu manaʻo, loaʻa iā EN39 S235GT a me Q235 nā haku mele like ʻole akā ʻokoʻa iki nā ʻano mīkini. ʻO ka koho ma waena o nā mea ʻelua e pili ana i ka noi kikoʻī a me nā koi o ka papahana.
