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.

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.

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.

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.

ASTM A312 TP316 is a standard specification for seamless, straight-seam welded, and heavily cold worked welded austenitic stainless steel pipes used in high-temperature and general corrosive service applications. The 316 Seamless Industrial Steel Pipe is made from a combination of chromium, nickel, and molybdenum, which gives SS 316 Seamless Tube excellent resistance to corrosion and rust.

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.

For 304 stainless steel tube heat resistance, it has good oxidation resistance in intermittent use at 8700C and continuous use at 9250C. Continuous use of 304 in the 425-8600C range is not recommended if subsequent water corrosion resistance is important. Grade 304L is more resistant to carbide precipitation and can be heated to the above temperature range.

316 stainless steel pipe is made from either solid chromium or a chromium and nickel combination. Types of stainless steel pressure pipe include seamless and welded pipe, electric fusion welded pipe for high-pressure applications, large diameter welded pipe for corrosive or high-temperature applications, and seamless and welded ferritic and austenitic stainless steel pipe.

316 stainless steel has a similar chemical composition to 304, but also contains molybdenum. This addition makes it more resistant to corrosion. Like 304, the 316 formulation does not require post weld annealing. 316L stainless steel is almost the same as 316. The only difference is the carbon content. The low carbon content of 316L imparts better corrosion resistance than 316. 316L does not require post weld annealing.

316 is usually regarded as the standard marine grade stainless steel, but it is not resistant to warm sea water. In many marine environments 316 does exhibit surface corrosion, usually visible as brown staining. This is particularly associated with crevices and rough surface finish.

316L stainless steel is an ultra-low carbon version of 316 stainless steel that helps avoid carbide precipitation from welding. Grade 316 stainless steel has a lower chromium content¡ªtypically around 16%¡ªbut increases the nickel content and adds molybdenum to the mix.

SS 304 alloy steel is used in the development of pipes. However, the alloy is composed of chromium and nickel, which provide pipes and tubes with various properties. In addition to this, SS 304L has a lower carbon content than 304 alloy steel. This is how it excels at being resistant to intergranular corrosion. Likewise, SS 304H is an alloy for high temperature applications, with high temperature strength and the ability to operate at high temperatures.

304L is a variant of 304 stainless steel with a lower carbon content and is used where welding is required. The lower carbon content minimizes carbide precipitation in the heat-affected zone near the weld, which can lead to intergranular corrosion (welding corrosion) of stainless steel in some environments.

These low-carbon pipes, however, suffers from yield-point runout. The SA 312 TP304 Square Pipe can be easily installed in difficult areas in houses and buildings.

SMO 254 ERW pipe is used where the properties and corrosion resistance of steel are required. The high molybdenum and chromium content also makes SMO 254 square tube highly resistant to acids that can cause pitting.

304 Stainless Steel Pipe is however susceptible to corrosion from chloride solutions, notably saline environments with high amounts of sodium chloride (salt). ASTM A358 TP304 is a great choice for general stainless steel applications such as kitchen and food processing applications, liquid storage and tanks, heat exchangers, building facades, pressure vessels and other applications involving fresh water environments.

Type 304 stainless steel is an austenitic grade that can be heavily deep drawn. This characteristic has led to 304 being the primary grade used in applications such as sinks and pans.

The higher carbon grade 316H can be used at elevated temperatures, as is the stable grade 316Ti.

316 Stainless Steel’s resistance to corrosion and contamination, low maintenance, and a familiar luster make stainless steel an ideal material for many applications that require the strength and corrosion resistance of steel. In addition, stainless steel can be rolled into sheet, plate, bar, wire and tube. These can be used in cookware, tableware, surgical instruments, major appliances, vehicles, construction materials in large buildings, industrial equipment (eg, paper mills, chemical plants, water treatment), and storage tanks and tankers for chemicals and food.
