SS400 Non-Alloy Bar Steel is a widely used carbon steel, popular in structural and construction applications. SS400 is known for its good mechanical properties, ease of fabrication, and cost-effectiveness. This steel can be welded, cut, and machined into various shapes and sizes, serving a wide range of industrial purposes.

Key Characteristics of SS400 Non-Alloy Bar Steel:

- Chemical Composition:
- Carbon (C): Max 0.25%
- Manganese (Mn): Max 1.20%
- Phosphorus (P): Max 0.050%
- Sulfur (S): Max 0.050%
- Iron (Fe): The remainder

- Physical Properties:
- Tensile Strength: Minimum 400 MPa
- Elongation: Minimum 20%
- Weldability: Very good, does not require pre-heating before welding
- Machinability: Easy, suitable for cutting, welding, and forming

- Applications:
- Construction and Structural: Widely used in construction structures such as bridges, warehouses, steel frames, and other supporting structures
- Machinery Manufacturing: Used in machinery parts and mechanical components that do not require high strength and durability
- Industrial Components: Used in the production of machine parts and industrial equipment

- Shape and Size:
- SS400 is typically supplied in round bars, square bars, rectangular bars, or other shapes according to specific application requirements

Manufacturing and Processing:
- SS400 is produced through hot rolling processes, and can then be fabricated into final products through methods such as cutting, welding, and forming. This steel can also be galvanized or coated to enhance its corrosion resistance.
