What is ASTM A105?
ASTM A105 is a standard specification for carbon steel materials defined by the American Society for Testing and Materials (ASTM). It is one of the commonly used materials in the forging industry. ASTM A105 has excellent forgeability, good corrosion resistance, high strength, and is easy to machine. In the die forging industry, it is widely used in petroleum and chemical equipment, energy equipment, and other machinery industries.
Chemical Composition of ASTM A105
ASTM A105 is a carbon steel material with the following key chemical elements:
| Element | Content (%) |
|---|---|
| Carbon (C) | ≤ 0.35 |
| Manganese (Mn) | 0.60–1.05 |
| Phosphorus (P) | ≤ 0.035 |
| Sulfur (S) | ≤ 0.040 |
| Silicon (Si) | 0.10–0.35 |
| Copper (Cu) | ≤ 0.40 |
| Nickel (Ni) | ≤ 0.40 |
| Chromium (Cr) | ≤ 0.30 |
| Molybdenum (Mo) | ≤ 0.12 |
| Vanadium (V) | ≤ 0.08 |
The relatively high manganese content enhances the hardness of the material.
Advantages of ASTM A105 forged fittings
Using ASTM A105 material in die forging offers many advantages, including:
High Strength and Toughness
The forging process refines the grain structure, enhancing impact and fatigue resistance.Excellent Machinability
Forged materials have a uniform structure, making them easier to machine and reducing tool wear.Outstanding Pressure Resistance
Suitable for high-pressure piping systems, such as valves, flanges, and fittings.Good Weldability
The low carbon content and proper alloying elements allow for easy welding using various processes (e.g., SMAW, GTAW).High-Temperature Resistance
Operates effectively in temperatures ranging from -29°C to 425°C, suitable for high-temperature, high-pressure environments.
