**A105 Carbon Steel Overview**

ASTM A105 is a specification that covers forged carbon steel piping components for ambient- and higher-temperature service in pressure systems. This includes flanges, fittings, valves, and similar parts which are used in the oil, gas, petrochemical, and other service industries. A105 is commonly used for manufacturing piping components where high durability and pressure endurance are required.

**Key Features of ASTM A105 Carbon Steel:**

- **Material Composition:** A105 steel is primarily composed of carbon and manganese, which gives it the necessary strength and toughness required for high-pressure and high-temperature applications.
- **Mechanical Properties:**
- **Tensile Strength:** Typically ranges between 70,000 psi and 95,000 psi.
- **Yield Strength:** Minimum yield strength of about 36,000 psi.
- **Elongation:** Usually about 22-35% in 2 inches.
- **Heat Treatment:** The A105 carbon steel can be heat treated by annealing, normalizing, or normalizing and tempering to achieve desired properties of hardness and ductility.

**Applications of ASTM A105 Carbon Steel:**

A105 is particularly suited for use in environments where temperature fluctuations are significant and where high durability is essential. Common applications include:

- **Valves, Flanges, and Fittings:** Often used in the manufacture of industrial pipeline systems to control flow and pressure.
- **Pressure Systems:** Suitable for both high-temperature and high-pressure environments typically found in the oil and gas industry.
- **Repair Sleeves:** Utilized in pipeline service repairs due to its robustness and resilience.

ASTM A105 is favored in industrial applications because it offers a good balance of strength, flexibility, and performance in harsh environments, ensuring reliability and safety in critical service conditions.
