ASTM A105 covers forged carbon steel components used in piping systems for ambient- and higher-temperature service in pressure systems.
ASTM A105 Carbon Steel Forgings
High Quality ASTM A105 Carbon Steel Forgings
SSM provides 105 forgings and forged components made from ASTM A105 carbon steel. ASTM A105 is a standard for carbon steel forgings, mainly used for pressure vessel components, particularly in piping systems at ambient and higher temperatures. The forged products made from ASTM A105 steel that SSM provides include Flanges, Fittings, Valves, and Other similar parts.
Our forgings are widely used in the oil, gas, chemical, and power generation industries, especially in high-pressure and mechanically demanding environments. “105 forgings” refers to forgings made from ASTM A105 steel, which has excellent mechanical properties, such as high strength, durability, and resistance to stress cracking.

Application of ASTM A105 Forgings
ASTM A105 forgings are used in various industries where high strength and pressure resistance are required. Key applications include:
- Piping Systems: Used in flanges, fittings, and valves for high-pressure systems, especially in oil, gas, and power generation industries.
- Pressure Vessels are used for components in pressure vessels operating at ambient and higher temperatures.
- Oil and Gas: Essential for pipe connections, valves, and other components in drilling and transportation.
- Chemical and Petrochemical Plants: These are used in piping and reactors due to their resistance to pressure and chemical environments.

Note—The above table gives the computed minimum elongation values for each 1⁄32-in. [0.8-mm] decrease in wall thickness. Where the wall thickness lies between two values shown above, the minimum elongation value is determined by the following equation: E=48T+15.00
where:
E = elongation in 2 in. or 50 mm, %, and T = actual thickness of specimen, in. [mm].
