- ASTM A105 Flange
Nace certified ASME SA 105 Slip On Flange and A105n Blind Flange supplier in Mumbai
The ASTM A105 can be defined as a specification for the flanges. It can include various grades of the stainless steel material that makes up the flanges. The ASTM A105 Flange is mostly of the forged carbon steel and they are usually used in high-temperature services. The ASTM A105 material consists of different elements in its chemical composition; it has chromium and molybdenum in its alloy which increases the hardenability of the flanges. Different types of flanges are available in this specification and each of them have separate applications according to its structure. For example, the ASTM A105 Blind Flange is used for closing a pipeline. These flanges are also known for their high strength. The minimum yield strength of the ASTM A105 Flange is 250 MPa and its minimum tensile strength is 485 MPa. The material has a Brinell hardness score of 187.
The ASTM A105 Flanges are available in different pressure classes, such as class 150, 300, and it goes up to 2500, and from PN6 to PN64. Any ASTM A105 Flange below class 300 do not need heat treatment, while the flanges with higher pressure classes might choose to undergo heat treatment. These flanges can be forged and they possess high weldability. These flanges are also available in the bolted and screwed forms, which are applied to the threaded pipes for making a connection.
The ASTM A105 Flange offers several benefits like they are resistant to corrosion, and has advantages in oxidizing media like nitric acid solution. It is because the ASTM A105 material has low content of molybdenum. They have a smooth and simple sealing surface which makes it very easy to machine them.
ASTM A105 Sorf Flange Vs ASME SA105 Blind Flange
The ASTM A105 Sorf Flange or Slip-on Raised Face Flange are mostly used for various fabricated applications. They are basically attached to the pipe with the help of a filler welding that is present at the hub and also at the pipe end, on the inner side of the flange. The ASTM A105 Sorf Flange is available in various sizes and they can be used for various applications. It is mostly used for low temperature and low pressure applications. These slip-on flanges are preferred by engineers of industries such as oil and gas, due to its affordability.
The ASME SA105 Blind Flange does not have a hub or a center with a bore. They basically have the face thickness of a flange with a matching face type and there is also a similar bolting pattern. It is mostly used for sealing the nozzle opening of a pressure vessel, or the end of the pipe to stop the connection. They are used on that nozzle of a vessel or part of the pipe that is not under any use, as it completely blocks off the operation.
Is A105 Carbon Steel Class 150 Flange low temp?
The A105 Carbon Steel Flange is capable of withstanding different pressure at different temperatures. Generally, with the increase in the temperature, the pressure rating of the flange decreases. For example, the A105 Carbon Steel Class 150 Flange is rated at around 270 PSIG at ambient conditions whereas it is approximately 180 PSIG at 204 degrees C. Thus as the pressure goes down, the temperature increases, and vice-versa. Thus, generally it can be said that the A105 Carbon Steel Class 150 Flange is low temperature.

ASTM A105n Flange Vs SA 105 Flange
There is no difference between the chemical composition of the ASTM A105n Flange and the SA 105 Flange. However, the difference lies in its standard and mechanical properties. Basically, when there is an auxiliary requirement for heat treatment for the ASTM A105 material in normalized condition, it is known as the ASTM A105n material. The SA 105 Flange does not have any heat treatment requirements. Thus, it can be said that the ASTM A105n Flange possesses better mechanical properties compared to the ASTM A105 Flange as the former have increased strength and give better performance at low temperature services. Thus, it can be concluded that even though the ASTM A105n Flange and the SA 105 Flange have the same chemical composition, the ASTM A105n Flange has enhanced mechanical properties and that is why they are used for critical applications.

ASTM A105 Heat Treatment
- Annealing-During annealing, the material is uniformly reheated to a temperature above the transformation range and then slowly cooled to a temperature below the transformation range after holding at this temperature for a suitable time.
- Normalizing-The material is uniformly warmed to a temperature above the transformation range and then cooled in room temperature air.
- Normalizing and tempering
- Quenching and tempering-In this procedure, the material is thoroughly austenitized before being instantly quenched in an appropriate liquid medium. The quenched fittings were then warmed to a minimum temperature of 590°C (1100°F) and chilled in still air.

ASTM A105 vs IS 2062 material
ASTM A105 is the most generally used carbon steel material grade for forging piping components such as flange and forged fittings of small diameter piping, whereas IS 2062 is a steel product standard of the Bureau of Indian Standards. It establishes requirements for Hot Rolled Medium and High Tensile Structural Steel. These steels are utilised in structural applications.
