Q235 is a common carbon structural steel widely used in construction, machinery, bridges, vehicle manufacturing and other fields. It complies with the relevant provisions of China's national standard GB/T 700-2006.
Q235 is a common carbon structural steel widely used in construction, machinery, bridges, vehicle manufacturing and other fields. It complies with the relevant provisions of China's national standard GB/T 700-2006. The main features of Q235 steel include:
1. Composition:
The main alloying element of Q235 steel is carbon, and the carbon content is generally between 0.12%-0.20%. Its alloying element content is low, mainly composed of iron, carbon, a small amount of manganese, sulfur, phosphorus and other elements.
2. Moderate strength:
The yield strength of Q235 steel is 235 MPa (megapascals), hence the name "Q235". Its tensile strength is usually between 375-500 MPa. It is suitable for some structures that do not require particularly high strength.
3. Good plasticity and toughness:
Q235 steel has good processability and plasticity, is easy to weld, bend and stretch, and therefore has high adaptability in the manufacturing process.
4. Good welding performance:
Due to its low carbon content, Q235 steel is not prone to cracks during welding, has good welding performance, and is suitable for various welded structures.
5. Corrosion resistance:
Q235 steel has relatively poor corrosion resistance and needs to be galvanized or painted to improve its weather resistance. In common applications, surface protection measures are used to increase its service life in harsh environments.
6. Machinability:
This material has good machinability and can be machined, forged, stamped and other processing technologies, so it is widely used in the manufacture of various types of machinery and equipment.
7. Scope of application:
Q235 steel is widely used in the manufacture of various products such as building structures, bridges, mechanical parts, boilers, pressure vessels, etc. In addition, it is also used in the production of automobiles, ships, etc.
8. Earthquake resistance:
In the field of construction, Q235 steel also has good earthquake resistance and is suitable for some areas with frequent earthquake activities.
9. Economical price:
Due to the low carbon content and simple synthesis of Q235 steel, its price is relatively economical and suitable for mass production with limited budget.
