What is ASTM A105 Flange?
ASTM A105 flanges, forged from carbon steel, are suitable for industrial high-pressure and high-temperature environments. Carbon steel flange dimensions are specified by standards such as ASME B16.5/ASME B16.47. Jinie is a manufacturer and supplier of A105N flanges. We can customize sizes according to customer requirements.

Advantages of A105 Carbon Flanges
High Strength and Durability
High Temperature Resistance: Operates from -29°C to 425°C
Corrosion Resistance: A105 flanges can withstand corrosion through coatings or linings.
Low Cost: Carbon steel raw materials (iron and carbon) are significantly less expensive than stainless steel or nickel alloys.
ASTM A105 VS ASTM A350 LF2
A350 LF2 is a carbon steel alloy suitable for low-temperature environments (down to -46°C / -50°F).
A105 is suitable for environments ranging from ambient to high-temperature, high-pressure environments.
