AL6XN is a superaustenitic stainless steel with outstanding resistance to chloride pitting, crevice corrosion and stress corrosion cracking. AL6XN is a 6 moly alloy that was developed for and is used in highly aggressive environments. It has high nickel (24%), molybdenum (6.3%), nitrogen and chromium contents that give it excellent resistance to chloride stress corrosion cracking, chloride pitting, and exceptional general corrosion resistance. AL6XN is primarily used for its improved pitting and crevice corrosion resistance in chlorides. It is a formable and weldable stainless steel.

The 316 stainless steel pipe has become an indispensable material for the industrial sector. This alloy of iron and chrome is recognized for its high resistance to corrosion, as well as its durability. 316 stainless steel tubing can be produced in both seamless and welded tubes to meet specific customer needs.

UNS N08367 also commonly referred to as alloy AL6XN is a low carbon, high purity, nitrogen-bearing “super-austenitic” nickel-molybdenum alloy with excellent resistance to chloride pitting and crevice corrosion.

A flange is a ring of steel (forged, cut from plate, or rolled) designed to connect sections of pipe, or to join pipe to a pressure vessel, valve, pump or other integral flanged assembly. Flanges are joined to each other by bolts, and to the piping system by welding or threading (or loose when stub ends are used). Stainless steel flange simplified as SS flange, it refers to the flanges that made of stainless steel. Common material standards and Grades are ASTM A182 Grade F304/L and F316/L, with pressure ratings from Class 150, 300, 600 etc and to 2500. It used in more industries than carbon steel as stainless steel has better resistant performances on corrosion environment and always provides with a good appearance.

Chromium, nickel, and iron are the primary alloying elements in austenitic stainless steel.

UNS NO8904, commonly known as 904L, is a low carbon high alloy austenitic stainless steel which is widely used in applications where the corrosion properties of AISI 316L and AISI 317L are not adequate.

The regular products of A403 WP321 pipe fittings are elbows,tees,reducers,caps,cross.

The flanges are made from 310S stainless steel, which is a heat-resistant austenitic stainless steel alloy. 310S Stainless Steel Flange contains high levels of chromium (24-26%) and nickel (19-22%) to provide superior corrosion resistance and high-temperature strength.

To keep track of the distinguishing characteristics of steel, manufacturers have created a naming system that is both systematic and exhaustive.

Flanges made of stainless steel are called “stainless steel 304 flanges”, also referred to as “SS 304 flanges”. Common material standards and grades include ASTM A182 Grade F304/L and F316/L, with pressure ratings of 150 to 2500 and 300 to 600, respectively.

Stainless steel has been in use for more than one hundred years.

Greater strength and corrosion resistance still mandate the use of seamless stainless steel and nickel alloy tubing for high pressure applications within the oil and gas, petrochemical, chemical, energy, and pulp and paper industries.

Type 316/ 316L/316H are austenitic stainless steel intended for use in applications that require high strength, toughness and workability, as well as enhanced corrosion resistance.

304 stainless steel is the most common stainless steel. The steel contains both chromium (between 18% and 20%) and nickel (between 8% and 10.5%)[1] metals as the main non-iron constituents. It is an austenitic stainless steel.When it comes to uses, SS304 can be found in kitchen sinks and other appliances such as toasters and microwave ovens. SS304 is also used to make pressure vessels, wheel covers as well as for building facades.

Stainless steel UNS S31600 bolts are commonly used in food preparation machinery primarily in chloride atmospheres. SS 316 Hex Bolts are an austenitic nickel-chromium alloy containing molybdenum. SS 316 Heavy Duty Hex Bolts are the ideal steel for use in marine environments as it resists pitting corrosion better than any other steel grade.

304 also contains 8-10.5% nickel (Ni). It is added to make the austenite structure more stable at room temperature. Nickel also improves high temperature oxidation resistance, making the steel resistant to stress corrosion cracking. Where the steel is to be stretch formed, a lower percentage (8%) of nickel should be chosen. Higher percentages are better (9% or more) if the steel is to be deep drawn.

S31803 is the Unified Numbering System (UNS) designation for the original duplex stainless steel. The UNS system was created by multiple trade groups in the 1970s to reduce confusion when the same alloy was called different things, and vice versa. Each metal is represented by a letter followed by five numbers, where the letter represents the metal series, i.e. S for stainless steel.

For paper mill applications requiring lower alloy grades that do not have sufficient corrosion resistance. Based on a 22% chromium content, they have a combined austenitic:ferritic microstructure that provides greater strength, corrosion resistance and cost-effectiveness.

The UNS S31803 (ASTM F51) specification has been largely superseded by UNS S32205 (1.4462, ASTM F60). This reflects their desire to maximize the alloy’s corrosion properties, thanks to the development of the AOD steelmaking process, which allows for tighter control of composition. In addition, it allows to influence the nitrogen addition level rather than just being present as a background element. Therefore, the highest performing duplex grades seek to maximize the content of chromium (Cr), molybdenum (Mo) and nitrogen (N).

The grade is non-magnetic in all conditions and has excellent formability and weldability. The austenitic structure also gives this grade excellent toughness, even down to cryogenic temperatures.
