Characteristics
-
Good Plasticity: 35-grade steel has good plasticity, allowing it to deform under force without breaking easily.
-
Adequate Strength: It has a moderate level of strength suitable for a variety of mechanical and structural applications.
- Good Workability: The steel has good workability, making it easy to machine and heat treat.
- Acceptable Weldability: While not its strongest feature, 35-grade steel's weldability meets general requirements.
- Heat Treatment Applicability: It can be improved in mechanical properties through heat treatments such as normalization and tempering, adapting to various operating conditions.
-
Wide Application Range: Due to its properties, 35-grade steel is widely used for manufacturing mechanical parts, structural components, and tools.
