GB/T700 GB/T3274 Q235B低碳钢板/碳钢板等效于ASTMA36、A283Gr.C EN10025-2S235JR, JIS G3101SS400, DIN 17100St37-2等软钢材料。但它们也有一些不同。Q235B软钢板/carbon steel plates have 2 standards at present: GB/T700 and GB/T3274. GB/T3274 is new version, but a lot of mills still conduct GB/T700 at present. Please contact katalor steel for more information of GB/T700 GB/T3274 Q235B mild steel plates/carbon steel plates, and katalor technician will give helpful suggestions to you according to your projects.
