Smelting method: Q355NE Steel is smelted by converter or electric furnace, and can be refined outside the furnace if necessary. Unless the buyer has special requirements and is indicated in the contract, the smelting method is generally chosen by the supplier.
Q355NE low alloy steel is suitable for electric power towers, various types of cranes, heavy vehicles, oil derricks, high temperature fans, large electric shovel, dump trucks and drilling rigs, coal mine hydraulic supports, steel structures, etc.
