Manifold - Model ASTM A105 -Carbon Steel Flanges

is a low carbon, manganese and silicon containing steel grade. Though the alloy used to produce a105 carbon steel flanges is similar to the AISI 1330 specification, the difference between both these standards is that  a105 carbon steel flanges manufacturers make this alloy with a lower manganese content.

While heat treating the astm a105n weld neck flanges is not a mandatory requirement, with the except for flanges above Class 300, the a105 pipe flange of special design (where the design pressure or design temperature for the carbon steel a105 reducing flange are not known. This also holds true for items over 4” NPS and above Class 300. When the a105 carbon steel plate flanges require heat treatment, processes like  annealing, normalizing, normalizing and temper, normalizing and quenching and tempering shall be the applied to the forged carbon steel astm a105.

Forgings for this specification astm a105 150 flange dimensions are limited up to 10,000 lbs. The astm a105 flange material alloy is forged at between 1,700  °F and 2,200  °F, followed by quenching and tempering the astm a105 class 300 flange.Forged parts of the carbon steel grade a105 are first allowed to cool down to a temperature below 1,000 °F. After cooling down the astm a105 flange , it is then reheating to a temperature range  between 1,550 °F and 1,700 °F. Once the carbon steel a105 blind flange has been reheated, the alloy is cooled slowly in the furnace.

Machinability of the astm a105 slip on flange carbon steel forging is good as any other grades of the low alloy steels. Other than machining, the carbon steel a105 flanges specification does not cover cold working. In order to confirm the strength and ductility of the material, the astm a105 blind flange is required to undergo tests like tensile test and hardness test. These tests are performed on the astm a105 sorf flange specimen, which is then cut out from the sample that was heat treated along with the final product.

We are one of the leading a105 flange manufacturers.
