**2. Shapes and Sections:**
Low & Medium Carbon Steels and Boron Steels are available in a variety of shapes and sections, including:
- Rounds (bars): Diameter range from 5mm to 300mm
- Squares (bars): Size range from 5mm to 200mm
- RCS (Rolled and Contoured Sections): Size range from 10mm x 10mm to 200mm x 200mm
- Flats: Thickness range from 3mm to 100mm, width up to 500mm
- Hexagons: Across flats from 6mm to 100mm
- Wire: Diameter range from 1mm to 20mm
**3. Production Routes:**
These steels can be produced using various production routes, including:
- Non-vacuum degassed route: This route is commonly used for standard-grade steels and involves the conventional steelmaking process without vacuum degassing.
- Vacuum degassed route: This route involves additional vacuum degassing, resulting in higher purity and improved properties, suitable for critical applications.
**4. Machinable Conditions:**
Low & Medium Carbon Steels and Boron Steels are offered in various machinable conditions, such as:
- As rolled: The steel is delivered in the as-rolled condition, suitable for general machining and fabrication.
- Annealed: Annealing improves machinability by softening the steel for easier cutting and forming.
- Normalized: Normalizing provides uniformity in grain structure, enhancing machinability and mechanical properties.
- Spheroidize annealed: This process improves machinability and formability by forming spheroidal carbides in the steel microstructure.
- CHQ (Cold Heading Quality): CHQ steels are designed for cold forming operations, making them ideal for producing fasteners and other cold-headed components.
