Q235B is a code name for carbon steel, which means B-grade carbon structural steel with a yield point of 235MPa.
The chemical composition of Q235B carbon steel is mainly carbon, silicon, manganese, sulfur, phosphorus, chromium, nickel, copper and so on. Q235B carbon steel has certain elongation, strength, good toughness and castability, and is easy to stamp and weld.
Q235B carbon steel has a wide range of uses, and most of Q235B carbon steel is used for welded, riveted or bolted steel structural parts. Q235B carbon steel is often rolled into wire rod or round steel, square steel, flat steel, angle steel, I-beam, channel steel and other steel products.
Q235B carbon steel can be used to make steel bars or build factory building frames, high-voltage transmission towers, bridges, vehicles, boilers, containers, ships, etc. Q235B carbon steel is also widely used for mechanical parts that do not require high performance.
