Carbon Steel Astm A105 Flange [SAFE – How-To]

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).

Excellent strength and toughness, high weldability, and good formability. CARBON STEEL ASTM A105 FLANGE

Used for small-bore, high-pressure piping. Maximum 0

Tapered hub, ideal for high-pressure/temp. Slip-On (SORF): Common in utilities; easier installation. Blind (BLRF): Seals pipe ends. Used for small-bore, high-pressure piping

Used for metal-to-metal sealing in high-pressure oil/gas. Standard Specifications

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).

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