High-quality materials are the foundation of reliable mechanical products. PRT Metal carefully selects proven engineering-grade steels to ensure that every component delivers strength, durability, and long-term performance in demanding industrial environments.
For our standard mechanical components, we rely on a selection of proven and widely used materials, including 45 steel, 42CrMo, Q235B, Q345,
45 steel
45 steel offers an excellent balance of strength, machinability, and cost efficiency, making it ideal for shafts, gears, pins, and general mechanical components.
42CrMo
For heavy-duty and high-stress applications, 42CrMo alloy steel is our preferred choice. Its superior strength and fatigue resistance make it well suited for critical transmission parts, mining equipment, and metallurgical machinery components.
Q235B
Q235B is widely used for welded structural parts and equipment frames thanks to its good formability and weldability, ensuring stable structures and reliable performance.
Q345
When higher load-bearing capacity is required, Q345 low-alloy structural steel provides enhanced strength while maintaining excellent welding characteristics, supporting robust and efficient equipment design.
By combining the right materials with precision machining and strict quality control, we deliver mechanical components that perform reliably, reduce downtime, and extend service life.
