Carbon Steel Flanges

ASTM A105 steel grade is the typical common material for forged carbon steel flanges (low carbon steel), which is used in many places in pressure systems for environmental and high temperature service. This material is durable, low cost and not easy to break. If used in stainless steel piping systems, lap end rings should be used.

Carbon steel flange is a kind of rim formed at the end of the pipe when it is fixed on the pipe. It is used to seal the ends of pipes, valves or other connections. It has high tensile strength and is available with convex surfaces and supports for easy installation. It is an iron-carbon alloy containing up to 2.1 wt.% carbon. Carbon steel does not have minimum specified levels of other alloying elements, but it usually contains manganese.

ASTM A350 (SA350) LF2 – Low Temperature Service, This carbon steel grade is designed for low temperature service and bears close resemblance to the ASTM A105N (SA105N) grade. This grade requires notched durability testing and is suitable for many industries.

The standard set for ASTM A694 is more stringent than the two above. It has very strict requirements for high-pressure fluid transmission in oil and gas pipelines. Due to the stringent conditions of the steel grades, manufacturers had to develop a stronger low temperature and high temperature steel. All grades of A694 have a minimum yield strength.

Flanges are devices used to connect pipes, pumps and valves in a piping system. There are different types of flanges, such as blind flanges, lap flanges, connecting flanges, welded flanges, etc. Carbon steel flanges are widely used in high demand due to their excellent corrosion resistance, excellent durability and good finish. These are used in petrochemical, chemical, power, agriculture and other industries.

Advanced materials are used to manufacture this product. It is even possible to use different sizes, gauges and thicknesses and build on that. CS flange materials are composed of mild steel and typically have pressure ratings from 150lb to 2500lb. The carbon content of medium carbon steel flanges is between 0.25% and 0.60%.

It contains a lot of carbon and manganese, so it is ductile and the product is well made. Killed carbon steel forged flanges, which means they are completely destroyed during the melting process. Deoxidation is due to the addition of silicon, manganese and aluminum during steelmaking.
