Q355B Material
Strength: Q355B is a low alloy structural steel with a yield strength of approximately 355 MPa. It offers good tensile strength and is suitable for moderate load applications.
Weldability: This material of excavator long arm is known for its excellent weldability, making it easier to fabricate complex structures.
Ductility: Q355B exhibits good ductility, which allows for some deformation under stress without fracturing.
Applications: Often used in producing long reach arm for excavator which working in general working environment and long reach arm long reach boom for excavator where moderate strength is required.
Q690D Material
Strength: Q690D is a high-strength structural steel with a significantly higher yield strength of around 690 MPa. This makes it ideal for heavy-duty applications.
Weldability: While it has good weldability, special attention must be paid during welding to avoid issues related to its high strength.
Ductility: Q690D provides good toughness even at lower temperatures, which is crucial for heavy-duty equipment like excavators.
Applications: Commonly used in applications requiring high strength and durability, such as cranes and heavy machinery.
Conclusion
Choosing between Q355B and Q690D depends on the specific requirements of the excavator long reach arm long reach boom. If the application involves high loads and stresses, Q690D would be the better choice due to its superior strength. However, for less demanding applications, Q355B provides an excellent balance of strength and weldability.
