The main characteristics of Q235 steel

Q235 steel is widely used in construction engineering, automobile manufacturing, shipbuilding, petrochemical and machinery manufacturing and other fields. However, due to its relatively poor corrosion resistance, it is necessary to take corresponding anti-corrosion measures during use to prolong its service life. What are the main characteristics of Q235 steel? Let's sum it up together!

1. Excellent plasticity and weldability. Q235 steel has good plasticity and can be formed by pressure processing, cold bending, hot bending and other methods. It also has good weldability, and can be connected and repaired by arc welding, gas welding, resistance welding and other methods.

2. Good mechanical properties. Q235 steel has high strength and toughness, and belongs to medium and low carbon steel. Its tensile strength is 370-500MPa, yield strength is 235MPa, and elongation is ≥26%. These mechanical properties enable Q235 steel to maintain stable performance under various stress states.

3. Q235 steel has certain corrosion resistance, but its corrosion resistance is relatively poor, and it is easily affected by the environment such as atmosphere, moisture, acid and alkali. Anti-corrosion measures need to be taken during use, such as coating, galvanizing, etc.
