AL-6XNalloy (UNS N08367) is a low carbon, high purity, nitrogen-bearing “super-austenitic” stainless alloy. The AL-6XN alloy was designed to be a seawater resistant material and has since been demonstrated to be resistant to a broad range of very corrosive environments. The high strength and corrosion resistance of the AL6XN alloy make it a better choice than the conventional duplex stainless steels and a cost effective alternative to more expensive nickel-base alloys where excellent formability, weldability, strength and corrosion resistance are essential.

Stainless steel is an alloy of iron that is resistant to rusting and corrosion. It contains at least 11% chromium and may contain elements such as carbon, other nonmetals and metals to obtain other desired properties. Stainless steel’s resistance to corrosion results from the chromium, which forms a passive film that can protect the material and self-heal in the presence of oxygen
Completely and infinitely recyclable, stainless steel is the ¡°green material¡± par excellence. In fact, within the construction sector, its actual recovery rate is close to 100%.
Stainless steel is also environmentally neutral and inert, and its longevity ensures it meets the needs of sustainable construction. Furthermore, it does not leach compounds that could modify its composition when in contact with elements like water.
Stainless steel must contain at least 10.5 percent chromium. Depending on the grade, it may contain much higher chromium levels, and additional alloying ingredients like molybdenum, nickel, titanium, aluminum, copper, nitrogen, phosphorous or selenium.
In addition to these environmental benefits, stainless steel is also aesthetically appealing, extremely hygienic, easy to maintain, highly durable and offers a wide variety of aspects. As a result, stainless steel can be found in many everyday objects. It also plays a prominent role in an array of industries, including energy, transportation, building, research, medicine, food and logistics.

INCOLOY 800H is widely used in Power generation, superheater and reheater tubing have also employed the material. Heat treatment retorts, muffles jigs and fixtures have also used this material to great effect.

Inconel Alloy 600 is designated as UNS N06600 and Werkstoff Number 2.4816.

A butt weld pipe fitting is designed to be welded on site at its end(s) to connect pipe(s) together and allow change in direction or pipe diameter, or branching or ending.

This fitting then becomes part of a system for transporting fluids (oil, gas, steam, chemicals, …) in a safe and efficient manner, over short or long distances.

Austenitic stainless steels are susceptible to stress corrosion cracking (SCC) in halide environments. Although type 316 alloys are more resistant to SCC than 18Cr-8 Ni alloys due to their molybdenum content, they are still susceptible. Conditions that produce SCC are: (1) the presence of halide ions (usually chloride ions), (2) residual tensile stress, and (3) temperatures in excess of about 120¡ãF (49¡ãC).

1.4529 German numeral code. Is a super duplex stainless steel, the main components: 20Cr-25Ni-6Mo-1Cu-0.2N corresponding to the United States: N08926, 254SMo…
1.4529 (UNS N08926) has very high resistance to pitting and crevice corrosion in halide media and in acidic environments containing sulfur and hydrogen
It can effectively resist chloride ion stress corrosion, and also has good corrosion resistance and good stability in oxidizing and reducing media.
The mechanical properties are slightly better than 904L, and it can be used in the manufacture of pressure vessels from -196 to 400 ¡ãC.

These duplex accessories are supplied in various industries such as brewing tanks, boiler construction and desalination plants. We stock a full line of 2205 Duplex Fittings to meet your piping requirements.

Owing to its high corrosion resistance– especially pitting and crevice resistance, Inconel 625 is an ideal for high saline, underwater applications.

The presence of this sigma phase in UNS S31803 dual-phase steel elbows is detrimental to the alloy because, in addition to the corrosion resistance of the material, it greatly reduces properties such as impact resistance at room temperature.

HT PIPE is one of the leading manufacturers of different types of high-quality products, such as pipe fittings of different shapes, sizes, thicknesses, etc. On the other hand, we are also a major supplier and exporter of the popular product duplex steel UNS S31803 pipe fittings. Pipe fittings are manufactured to all national and international standards of our organization. There are many kinds of pipe fittings, which are widely used in piping systems for various purposes. They are both used to mount profiled pipes to each other. In this way, liquids, fluids, gases, etc. pass through the pipes without any leakage. Also, fittings come in many sizes, sizes, standards, alloys, grades, etc., but most importantly our Duplex 1.4462 fittings are the most demanded fittings on the market today and for many years.

Austenitic stainless steel 304 L is favored by most buyers for its excellent weldability and is a low carbon version of the very popular alloy 304. Stainless steel 304L pipe fittings tend to be resistant to intergranular corrosion since the reduction in carbon means the alloy is not sensitized by grain boundary precipitates.
