, is a kind of carbon structural steel: .
Yield strength: . Lower than strength. The price is cheaper. Used in buildings, structures, motorcycle frames, etc.
United States: The brand name is (). That is, the yield strength is.
< B : < _ The Chinese national standard steel number represents the yield strength, which is the experimental value measured on a steel rod. If the diameter of steel is ~, the yield limit is, and the naming rule adopted in the United States is this.
< )br , chemical composition

It has high plastic toughness and welding performance, good pressure processing performance, but Low intensity.
< . Rolled sheet and wire rod. Cold and hot-rolled thin steel plates and galvanized, tin-plated and plastic composite thin steel plates made from them are widely used in roof panels, decorative panels, general dust removal pipes, packaging containers, iron barrels, instrument shells, switch boxes, protective covers, train carriages, etc. Wire rods are mostly cold-drawn into low-carbon steel wires or galvanized into galvanized low-carbon steel wires, which are used for binding, tensioning and fixing or as steel wire mesh rivets.
