ASTM A105 Flanges are forged carbon steel flanges commonly used in piping systems for connecting pipes, valves and other equipment. These flanges are manufactured from high-quality carbon steel materials and are supplied in different sizes and pressure ratings to suit a wide range of industrial applications. ASTM A105 carbon steel flanges are widely used in water supply systems, natural gas pipelines, power generation plants and various industrial piping projects.

ASTM A105 flanges are produced in accordance with several international standards to ensure consistent quality and performance. These include German standards such as DIN 2576, DIN 2573, DIN 2642 and DIN 2641, as well as British standards including BS 10, BS 4504 and BS 1560. In addition, flanges may also be manufactured according to Italian, Japanese and other international standards depending on project specifications.

The manufacturing process for ASTM A105 forged flanges involves controlled forging and heat treatment to achieve the required mechanical strength and durability. Alloying elements such as copper, nickel, chromium, molybdenum and vanadium are present in controlled proportions to improve the mechanical properties of the steel and ensure reliable performance in piping systems.

ASTM A105 flanges are generally available in sizes ranging from ½ inch to 60 inches (DN 15 to DN 2000). They are supplied in various pressure classes such as ANSI 150, 300, 600, 900, 1500 and 2500 depending on the application requirements. These forged carbon steel flanges are widely used with pipes, valves and fittings in industrial piping systems.

Because ASTM A105 is a carbon steel material, it is typically recommended for moderate temperature service. Prolonged exposure to temperatures above approximately 425°C may affect the material properties and could lead to reduced strength or corrosion over time.
