Impact Properties: J2: 27J at -20°C
Heat Treatment Process
Normalizing is performed between 890°C-950°C to refine the structure of forgings that may have cooled non-uniformly. The steel is held at temperature for sufficient time to complete the ferrite to austenite transformation, then cooled in still air.
Applications
S355J2 structural steel is widely used in engineering and construction industries where superior mechanical properties are required. Common applications include:
- Axles, bolts, and connecting rods
- Motor, hydraulic, and pump shafts
- Machinery parts and transmission towers
- Dump trucks, cranes, trailers, and construction equipment
- Highway bridges, building structures, and offshore platforms
- Shipbuilding, power plants, and industrial machinery
- Lifting equipment and port infrastructure
