1.Stainless Steel Wires

These are a group of Iron/Chromium/Nickel (300 series) and Iron-Chromium (400 series) steel alloys, resisting corrosion from practically all solutions except Hydrochloric, Hydrofluoric, or pure Sulphurous Acids; Bromine, Iodine, and aquaeous solutions of a few compounds of the Halogen Acids and of pure Sulphurous Acid. It must be remembered that corrosion resistance is largely dependent on galvanic action from contact with other metals. The analyses of the more common Stainless Steels are given in the adjacent Table. We will be glad to suggest the specific alloy best suited to your needs.

2.Wires of Nickel and Its Alloys

NICKEL
High-purity nickel spontaneously forms a passive oxide film, which resists corrosion under certain conditions. It shows excellent corrosion-resistance in normal atmospheres; distilled, fresh and salt water; neutral and alkaline salt solutions; acid salts, organic acids and compounds at normal temperatures; most acids except Nitric; and hot gases free of Sulphur. It does not readily discharge Hydrogen from any of the common acids with which it may be used. In general, reducing conditions tend to retard, while oxidizing conditions favor, the corrosion of Nickel. The oxidizing acids and alkaline salts are generally corrosive to Nickel. The many Nickel alloys, of which the principal varieties are described below, offer a wide range of characteristics that suit many requirements. We welcome inquiries regarding the exact alloy for any specific application.

Ni—SG 8.89—melts at 2633°F

MONEL 400
This alloy contains approximately 67% Nickel, 28% Copper, and 5% other elements. It is essentially non-corrodible, resisting Brine, Alcohol, Sulphuric Acid, hot gases, all alkalis, as well as normal atmospheres and distilled, fresh and salt water. Although more resistant than Copper to Oxidation, it is attacked by highly oxidizing conditions; Monel is more resistant than Nickel to reducing conditions, and is less expensive than pure Nickel. It is widely used in dry-cleaning equipment and in refrigeration, culinary and hospital fixtures.

INCONEL 600
This alloy contains 80% Nickel, 14% Chromium, 6% Iron. A tough, adherent oxide film forms on its surface, resisting further oxidation in Sulphur-free atmospheres at temperatures up to 2100°F; the Chromium content lends stainlessness to the surface without materially affecting its malleability. The strength of Inconel is comparable with that of steel. Limiting service temperatures are approximately as follows: for progressive oxidation, 2000°F; in oxidizing Sulphur atmospheres, such as Sulphur Dioxide, 1500°F; in reducing Sulphur, such as Hydrogen Sulfide, 1000°F. Inconel resists Ammonia and Nitrogen as encountered in nitriding and heat-treating operations, and is suitable for carburizing conditions. Inconel is the preferred material for heat-treating baskets.

INCONEL-X-750
This is an age-hardenable Nickel / Chromium / Iron alloy, highly resistant to chemical corrosion and oxidation after suitable thermal treatment. Its creep rate is low under high stress from 1200°F to 1500°F, and it retains a considerable portion of its room-temperature strength up to this temperature; above 1500°F, however, Creep strength falls off rapidly and its resistance to oxidation is inferior to that of regular Inconel. It is more expensive than Inconel, and must be age-hardened to achieve its maximum properties.

INCOLOY 800
32% to 36% Nickel, 19% to 22% Chromium, balance Iron, make this a workable, oxidation-resistant alloy that retains its strength at elevated temperature. In many ways Incoloy is similar to Type 330 Stainless Steel, with superior strength and corrosion resistance.Though less expensive than Inconel it is better in resistance to sulfidation, “green rot”, and molten cyanide salts; it is more or less inferior to Inconel in resistance to carburization.

INCOLOY 804
Nominally 42% Nickel, 30% Chromium, balance Iron, it resists carburization and oxidation and will not develop “green rot.” Incoloy 804 is free of embrittling phase changes during long heat-treating and develops good hot strength, making it useful for heat-treating baskets and other service at temperatures up to 1800°F.

INCOLOY 825
This alloy approximately contains 40% Nickel, 21% Chromium, 31% Iron, with a specific ability to withstand certain hot acids and oxidizing chemicals. It is considerably more resistant than the common Stainless Steel to reducing conditions such as hot Sulphuric, Sulphurous, and Phosphoric Acid solutions, because of its relatively high-Nickel content plus Molybdenum and Copper. The Chromium content, fortified with Nickel, gives Ni-O-Nel resistance to a wide variety of oxidizing agents such as Nitric Acid solutions and Nitrates, and to the salts (except the Chlorides) of Nitrates, Cupric, Ferric and Mercuric varieties. It handles hot Sulphuric Acid solutions with or without oxidizing agents under conditions where Nickel-Copper alloys and the common Stainless Steel are not satisfactory, and its good resistance to hot Phosphoric Acid is much superior to that of Type 316 Stainless.

3.Galvanized Steel Wires
According to the technique of production, the galvanized steel wire can be divided into Hot-Dipped Galvanized Steel Wire and Elcectro-Galvanized Steel wire.

Hot-Dipped Galvanized Steel Wire: In this progress, the wire is immersed in a bath of molten zinc. Practically only for steel wire cloth of 8 mesh or coarser.

Electro-Galvanized Steel Wire: An electrolytic process by which zinc particles are deposited on the cloth by the action of an electric current through an acid bath. Electrolytic galvanizing is generally confined to meshes ranging from 8 to 60 count. It produces a cloth that will withstand corrosion and maintain its pearl gray appearance. As in the hot-dip method, electro-galvanized deposits zinc coating at each intersection of wires which holds them firmly in place and preserves the uniformity of openings.

Uses: mainly for communications equipment, medical equipment and weave net, brushes, cables, filters, high-pressure pipe, construction, handicrafts and other fields
