N04400 is a ductile nickel-copper-based alloy consisting primarily of two-thirds nickel and one-third copper. Alloy N04400 is known for its resistance to a variety of corrosive conditions, including alkalis (or acid-like substances), brine, hydrofluoric acid, and sulfuric acid. Other advantages of using this alloy are toughness and high strength over a wide temperature range; it can also be manipulated to be magnetic if desired.

Monel 400? also has excellent resistance to stress corrosion cracking in most freshwaters.Our Monel Long Radius Elbow Fittings is available at various angles like 30 degrees, 45 degrees, and 90 degrees.

Besides these elements the addition of trace amounts of both Manganese and silicon, other set of common alloying elements, provides the alloy steel threaded flanges with excellent deoxidizing capabilities.

Alloy Steel Flanges are made in different steel alloys. The flanges vary in dimensions and types. There are ? inches through 48 inches of nominal diameter sizes of flanges.

The alloy steel slides on these flanges can be machined and polished in a stress-relieved condition.

The Alloy Steel Weld Neck Flange has a welded neck onto it that holds larger pipes in place for easy welding and installation.

Its greatest advantage is that it can be assembled without welding, which explains its use in low-pressure service at ordinary atmospheric temperatures and in highly explosive areas where welding creates a hazard.

HastelloyC-276 (Hastelloy) is a tungsten-nickel-chromium-molybdenum alloy with extremely low silicon-carbon content and is considered to be an all-around corrosion-resistant aluminum alloy. The key moisture-resistant chlorine, various air-oxidizing fluorides, isopropyl titanate solutions, hydrochloric acid and air-oxidizing salts, have good corrosion resistance in ultra-low temperature and standing temperature sulfuric acid. Therefore, in the past 30 years, it has been widely used in extremely corrosive natural environments such as chemical plants, petrochemicals, flue gas desulfurization, pulp and paper industry, and environmental protection.

Corrosion resistance

The aluminum alloy has the following characteristics: 1. It has good corrosion resistance to most corrosive substances under the two conditions of air oxidation and repair. ¢ÚIt has good resistance to pitting corrosion, void corrosion and intergranular corrosion. The higher content of Mo and Cr makes the aluminum alloy resistant to corrosion by chloride ion content, and the W element further improves the corrosion resistance. At the same time, Hastelloy C-276 aluminum alloy is one of the only types of raw materials that are resistant to wet chlorine, hypochlorite and chlorine dioxide saturated solutions. Ester solution has obvious corrosion resistance. It is one of the very few raw materials that can be used as a hot sulfuric acid saturated solution.

The achievable mechanical properties depend on added elements such as nickel, chromium, molybdenum and vanadium. The following are a series of improved properties of alloy steel (compared to carbon steel): strength, hardness, toughness, wear resistance, corrosion resistance, hardenability and hot hardness. To achieve some of these improved properties, the metal may require heat treatment.

A335 grade P5c pipe is a low alloy carbon steel (Cr-Mo) self-quenching in air where high hardness and residual stress are required for welding and it is not recommended for direct use in services requiring critical conditions. This situation requires the application of post weld heat treatment (PWHT). If you want to avoid PWHT then you can use preheat (120¡ãC) when soldering A335 grade P5c tubes. PWHT is required if the thickness of ASTM A335/ASME SA335 P5c alloy steel pipe is greater than 13 mm.
