Carbon Steel ASTM / A105N Flanges

The Carbon Steel ASTM / A105N forgings flanges are furnished in carbon steel, stainless steel, or alloy steel and manufactured by either an electric furnace, open-hearth or a basic oxygen process. Carbon Steel ASTM / A105N forgings flanges and forged fittings are manufactured from ingots, blooms, billets, slabs, or bars. However, Carbon Steel ASTM / A105N flanges are not machined directly from the plate nor from solid bar stock as sufficient hot working(forging) is essential to improve a wrought structure throughout the part.
All grades of Carbon Steel ASTM / A105N are heat treated. Heat treatment of carbon steel and high-strength low-alloy steel consist of normalizing, normalizing-and-tempering, or quenching and tempering. Heat treatment of alloy steel generally involves normalizing and precipitation heat treatment or quenching and precipitation heat treatment. The tempering temperature is at least 1000 °F [540 °C] and the precipitation heat treatment of the alloy steel is in the range from 1000 to 1225 °F [540 to 665 °C].
