Characteristics of Q235C steel

Q235C steel is a low-carbon structural steel in Chinese standard GB/T 700-2006. Its chemical composition mainly includes carbon (C), silicon (Si), manganese (Mn), phosphorus (P) and sulfur (S). and other elements. Specifically, the chemical composition requirements of Q235C steel plates are as follows: carbon content does not exceed 0.18%, manganese content is between 0.35~0.80%, silicon content does not exceed 0.35%, phosphorus content does not exceed 0.040%, and sulfur content does not exceed 0.035%. The proportions of these chemical components are precisely controlled to ensure that the steel plate has high strength, good ductility, weldability and other excellent comprehensive properties.

The characteristics of Q235C steel are mainly reflected in the following aspects:

Good plastic deformation: After plastic deformation treatment, Q235C steel plate can meet different shape and size requirements and has strong adaptability and plasticity.
Excellent welding performance: Q235C steel plate is suitable for various welding methods, such as arc welding, gas welding, submerged arc welding, etc. The material after welding has stable performance, smooth surface and high quality.
Good wear resistance and corrosion resistance: After special treatment and material combination, Q235C steel plate can withstand use in various corrosive environments and is not prone to rust and wear after long-term use.
Good low-temperature toughness: In low-temperature environments, Q235C steel plates still have good energy-absorbing capabilities and will not suffer from brittle fracture and other problems.
Good mechanical properties: Q235C steel plate has high strength and good ductility, and can withstand large loads and pressures.
Easy to process: Q235C steel plate can be made into parts of various shapes, has good forging performance, and can be completed by a variety of processes and equipment.
These characteristics make Q235C steel widely used in many fields, such as construction, bridges, machinery manufacturing, shipbuilding, railway construction, etc. Whether it is in structural parts that need to withstand large loads or in situations that need to withstand the challenges of corrosive environments, Q235C steel can show its excellent performance.
