Pōmaikaʻi Huahana

Q235BNo ke kila kalapona haʻahaʻa maʻamau, huahana kila me ka haʻahaʻa kalapona ma lalo o 0.3%, he palupalu loa ia no ka hana maʻalahi, ka mīkini, ka wili.He liʻiliʻi ka hopena o ka mālama ʻana i ka wela ma ka mea kila Q235B.Loaʻa iā ia kekahi mau mea ʻē aʻe e pili ana i ka mea hao: manganese, sulfur, phosphorus a me ke silika.ʻO ka hao a me kēia mau mea i hui pū ʻia e hana i ka waiwai mechanical kūʻokoʻa o Q235B, ʻaʻole like me ke kila kila me ka nickel a me ka chromium element, ʻaʻole ia e hōʻike i ke kūpaʻa corrosion maikaʻi.Inā makemake ʻoe i ka waiwai kūpaʻa i ka corrosion, ʻo ka pena ʻana me kahi papa o ka plating kahi koho maikaʻi.
