Description
This nickel
molybdenum alloy 2.4600 (alloy B3 or alloy B4) has good
stability against intergranular corrosion. Very high
resistance against reductive media such as hydrochloric
acid and sulfuric acid over broad concentration and
temperature ranges. 2.4600 (alloy B3 oder alloy B4) is
used with acetic acid, hydrogen chloride, sulphuric
acid, phosphoric acid, production of phenol, styrene
plants.
Our product range in 2.4600 (alloy B3 oder alloy B4) are
tubes and pipes, fittings and flanges, accessories.
