Alloy material production export

Grade: 904L(UNS N08904) (1.4539) pipes and tubes

Properties:

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:

Equipments 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.

Equipments for sea water processing, paper making, sulfur, nitric acid and pharmacy.

Food equipment/jars/bottles; centrifugal machine, reactors used in pharmaceutical factory.

Available Standards:

ASTM/ASME A312/SA312; A269; ASME B677; EN10216-5

Chemical Composition:

Ni:24.0%-26.0%; Cr:19.0%-21.0%; Mo:4.0%-5.0%; C:0.02%max; Si:0.7%max; Mn:2.0%max; P:0.030%max; S:0.010%max; N:0.50%max; Cu:1.0%-2.0%
