Carbon Steel Astm A105 Flange (2025)

Maximum 0.35% Carbon (C), 0.60–1.05% Manganese (Mn), and low sulfur/phosphorus. Mechanical Strength: Tensile strength ≥is greater than or equal to 485 MPa (70,000 psi), Yield strength ≥is greater than or equal to 250 MPa (36,000 psi).

ASTM A105 is the most widely used standard specification for forged carbon steel piping components, including flanges, fittings, and valves, designed for ambient- and higher-temperature service in pressure systems. These components are essential in industries like oil and gas, petrochemicals, and power generation due to their high strength and durability. Material: Forged carbon steel (killed steel). Service Temp: −20°F to 800°F (−29°C to 427°C). CARBON STEEL ASTM A105 FLANGE

Normalizing is required for larger sizes or high-pressure classes (e.g., above 2 inch, Class 600+) to improve grain structure. Common Flange Types Maximum 0
