316L 1.4401 S31603 Stainless Steel Pipe is a highly versatile and durable pipe option commonly used in a wide range of industrial and commercial applications. This SS UNS S31603 pipe is made from high quality 316L stainless steel with excellent resistance to corrosion, oxidation and staining, making it ideal for harsh environments or high stress applications.

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.

SMO 254 Pipes can withstand high mechanical stress and Alloy 254 SMO Pipe high pressure work in high temperatures and corrosive environments.

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.

316 stainless steel has more carbon in it than 316L. This is easy to remember, as the L stands for “low.”

The SS 904L coil is used in heat exchangers and in high temperature applications because of their high melting range of 1300 to 1390 degrees Celsius.

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.

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).

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.

The 310 310S Stainless Steel Flange has 1402 degrees Celsius melting point which allows them to operate under high temperatures.

Austenitic stainless steel alloy 316 / 316L is a molybdenum-bearing grade. The high nickel and molybdenum content in these pipes offer better overall corrosion resistant properties compared to 304 grade SS. This resistance is particularly useful regarding pitting and crevice corrosion in chloride environments. Moreover, 316 / 316L stainless steel tubes and pipes demonstrate exceptional high temperature tensile, creep, and stress-rupture strengths. Formability and weldability is also excellent. Unlike grade 316, 316L pipes are immune from sensitization, due to lower carbon content. Thus, it is commonly used in heavy gauge welded components.

Style 18-8 and Style 316 stainless steel bolts are available in most of our inventory. Type 18-8 is the standard grade, while 316 is a premium type commonly referred to as marine grade steel. It is known for its durability in harsh conditions that lead to rust or corrosion.

304 and 316 steels are specified for applications where corrosion resistance and product purity are still important but lack the stringent requirements in pharmaceutical, semiconductor or aerospace manufacturing. Cosmetics and food and beverage processing are examples.

The alloy has good oxidation resistance and creep strength to 1500¡ãF (816¡ãC). It also possesses good low temperature toughness.

The two most common stainless steel grades are 304 and 316. The main difference is the addition of molybdenum, an alloy that significantly improves corrosion resistance, especially in environments with more salt or chloride exposure.

Common uses for Type 316 stainless steel include the construction of exhaust manifolds, furnace components, heat exchangers, jet engine components, pharmaceutical and photographic equipment, valve and pump components, chemical processing equipment, tanks and evaporators. It is also used in pulp, paper and textile processing equipment and any components exposed to the marine environment.

For certain applications, grade 254 SMO has been reported to be a cost-effective substitute for high nickel and titanium alloys.

Stainless steel 904L / 1.4539 material can be used to make hot and cold rolled sheet and strip, semi-finished products, bars, rolled wire and profiles, as well as seamless and welded pipes for pressure applications.

In most cases, the corrosion resistance of our stainless steel 316 butt weld flanges is about the same in most corrosive environments.

ASTM A860 WPHY 52 Fittings are made up of a high yield carbon steel with carbon, manganese, sulfur, phosphorus, silicon, nickel, chromium, molybdenum, copper, titanium, vanadium and cobalt in the composition.The increased durability ensures a long work life, therefore proving that the A860 WPHY 52 elbow is a cost saving solution.

The Stainless Steel 304 Sheet also has manganese, carbon, silicon, sulfur, nitrogen and phosphorus in the composition. The material is strong and has 205MPa minimum yield strength and 515MPa minimum tensile strength in general.

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.

The Stainless Steel Fittings Manufacturers produce these fittings with the addition of manganese, phosphorus, carbon, silicon, and sulfur apart from the 2 main elements.

AL6XN alloy (UNS N08367) is a low carbon, high purity, nitrogen-bearing “super-austenitic” stainless alloy.

SMO 254 Hexagonal Pipes is subject to pitting and crevice corrosion in warm chloride environments and to stress corrosion cracking above about 60 Degree C.

316L is best known among manufacturers for crack resistance after the welding process is complete. This makes the 316L the first choice for manufacturers looking to build metal structures for industrial applications.

SAE 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. It is less electrically and thermally conductive than carbon steel. It is magnetic, but less magnetic than steel. It has a higher corrosion resistance than regular steel and is widely used because of the ease in which it is formed into various shapes.[1]

Basically, using 304L eliminates the need to anneal welded joints before using the full metal form, saving time and effort. In fact, both 304 and 304L can be used for many of the same applications. The differences are usually so small that one is not considered more useful than the other. When greater corrosion resistance is required, other alloys, such as grade 316 stainless steel, are often considered as an alternative.

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.

Flange, also known as flange plate or flange, is a part of connecting pipeline with pipeline and valve, which is connected with the end of pipeline. Flanges have holes. Flanges and flanges are tightly connected by bolts and sealed by gaskets.

Compared to chromium-nickel austenitic stainless steels, 316L stainless steel offers higher creep, stress to rupture and tensile strength at elevated temperatures.
