Properties of 904L super stainless steel pipes and tubes:
-
Super stainless steel, low carbon, high Ni and Mo.
-
Good activation-passivation transition ability, good resistance to sulfur, acetic acid, methane acid and phosphoric acid corrosion.
-
With low carbon (max 0.020%),there is no carbide precipitation in normal heat treatment and welding, thus eliminating subsequent risk of intergranular corrosion
-
Applications of 904L super stainless steel pipes and tubes:
-
Equipment like reactors for petro-chemical industry
-
Gas desulfurization equipment, like tower shell, flue, shutter spray system
-
Washers and fans used in organic acid process system.
-
Equipment for sea water processing, paper making, sulfur, nitric acid and pharmacy
-
Food equipment/jars/bottles; centrifugal machine, reactors used in pharmaceutical factory
