Carbon Steel - Astm A105 Flange

Anti-rust oil, yellow passivation, or hot-dip galvanizing. To provide a more tailored report, could you specify:

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

Used for metal-to-metal sealing in high-pressure oil/gas. Standard Specifications CARBON STEEL ASTM A105 FLANGE

ASME B16.5 (up to 24”), ASME B16.47 (Series A/B over 26”). Material: ASTM A105 / ASME SA-105.

Tapered hub, ideal for high-pressure/temp. Slip-On (SORF): Common in utilities; easier installation. Blind (BLRF): Seals pipe ends. Anti-rust oil, yellow passivation, or hot-dip galvanizing

Excellent strength and toughness, high weldability, and good formability.

Common in 150# to 2500# (Class 150-300 often "As Forged," higher classes usually normalized). Standard Specifications ASME B16

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).
