Q235B Carbon Structural Steel GB/T Q235B Carbon and Low-alloy Steel

Q235B Carbon Low-alloy Steel Description

The implementation standard of Q235B carbon and low-alloy steel plate is: GB/T3274, GB/T700 special technical conditions, Grade b in q235b means that in the quality grade symbol, it belongs to the b grade, and q235 means that it is a steel with a yield point of 235 MPa Carbon structural steel, Q235B steel has certain elongation, strength, good toughness and castability, easy for stamping and welding, and is widely used in the manufacture of general mechanical parts. It is mainly used for welded structural parts with high quality requirements in construction and bridge engineering.

Compared with Q235A steel, Q235B carbon structural steel belongs to carbon steel. In the national standard GB/T700-88, the material distinction between Q235A and Q235B is mainly in the carbon content of the steel. The material is that the carbon content of the material of Q235A is between 0.14-0.22%; It is a normal temperature impact test, V-shaped notch. Relatively speaking, the mechanical properties of steel made of Q235B are much better than those made of Q235A.

GB/T Q235B structural steel is a common low-carbon steel material. Its chemical composition is carbon (C), silicon (Si), manganese (Mn), phosphorus (P), sulfur (S) and other elements. It has stable mechanical properties and good processing performance. , Strong corrosion resistance and other characteristics. Its mechanical properties make it widely used in construction, machinery manufacturing, shipbuilding and other fields. Beibang Steel can provide Q235B plain carbon steel of various sizes and specifications, and can provide deep processing services such as cutting, welding, bending, shot blasting, and painting.
