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.

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.

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.

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.

If your outdoor appliance enclosure is rusted, not only is there a danger of exposing all critical electrical components inside, but it can be expensive to replace in the event of a short. We’re talking about parts damage and replacement, repair costs, including labor and downtime. I’ve seen some real horror shows when the shell is rusted. We have found that using 316 stainless steel instead of 304 stainless steel on outdoor enclosures that will be exposed to various elements, such as oil rigs, not only increases the life of the enclosure, it is also safer.

316 stainless steel is another popular stainless steel for applications requiring hardness, durability, and corrosion resistance, but it tends to have more specialized and limited uses than 304 stainless steel. The most notable property of 316 stainless steel is its extreme resistance to corrosion, especially from chloride sources such as seawater and many industrial chemicals.

304/304L stainless steel sheet is often used in cold forming operations during the application process. Its cold forming performance is an important technical indicator to measure whether the forming is smooth and the yield rate. The influencing factors of cold forming of 304 stainless steel are more complicated. As far as its metallographic factors are concerned, it is mainly the composition of the steel, that is, the ratio of chromium equivalent to nickel equivalent, and the elongation of conventional tensile properties is an important characterization index. In order to obtain good cold forming properties, the ratio of chromium equivalent to nickel equivalent in the steel needs to be controlled within an appropriate range.

Stainless Steel 316L tube is made of austenitic stainless steel with chromium, nickel and molybdenum in its composition, with a carbon content lower than grade 316. The low carbon content of the pipe makes it easier for welding applications.

Stainless steel is an alloy of iron that is resistant to rusting. 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.

304L is preferred. And it lacks a minimum carbon content, which is not ideal for high temperature applications where optimum strength is required, so 304H is the first choice. Thus, 304 is generally limited to rods or sheets that are to be machined into components that do not require welding, or sheets formed in articles, such as kitchen sinks or cookware, which are also not welded.

316 Stainless Steel Characteristics
Type 316 stainless steel tubing is similar to 304, but with the addition of molybdenum, which improves the alloys corrosion resistance. The austenitic structure allows excellent toughness, even down to extremely low temperatures. These grades have excellent weldability, with or without the addition of filler metal. 316 / 316L stainless tube is available as round, square or rectangular shapes. It is available as welded and seamless. It contains additional molybdenum and nickel than 304 stainless, which increases corrosion resistance of the metal. Decreased weldability is exhibited in 316L alloys due to increased carbon in the alloy. It is used for tube in more aggressive environments than 304 tube.

Fusion weldability of Type 304l stainless steel is excellent with or without fillers. The recommended filler rod and electrode for use with 304 stainless steel is grade 308 stainless steel. For 304L, the recommended packing is 308L. Heavy welded sections may require post weld annealing. The 304L does not require this step. If post weld heat treatment is not possible, grade 321 can be used.

Inconel Square Pipes is similar to other stainless steel but with a titanium addition of at least five times the carbon content. This addition in Inconel Rectangular Pipes reduces or prevents carbide precipitation during welding and in the 800 Degree C 1500 Degree F service conditions.

304 stainless steel is part of the austenitic steel family. One of the disadvantages of austenitic steels is that they cannot be hardened by heat treatment. In addition to this, 304 is a versatile stainless grade that can be drawn and formed easily. Hardness and strength can be increased by cold working. Good ductility in the annealed state. Additionally, 304L exhibits excellent corrosion resistance due to its ultra-low carbon composition.

The carbon content has a large effect on room temperature strength, so the specified minimum tensile properties for 304L are 5 kg per square inch (34 MPa) lower than for 304. However, nitrogen also has a large effect on room temperature strength, and the addition of very little nitrogen produces 304L with the same tensile strength as 304. So virtually all 304L is produced as dual certified 304/304L, which means it meets the minimum carbon content of 304L and also meets the minimum tensile strength of 304.

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.

Stainless steel is an alloy of iron that is resistant to rusting. 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.
A stainless steel pipe system is the product of choice for carrying corrosive or sanitary fluids, slurries and gases, particularly where high pressures, high temperatures or corrosive environments are involved. As a result of the aesthetic properties of stainless steel, pipe is often use in architectural applications.

For applications where stainless steel tubing or piping must come into contact with food and other sensitive products, sanitation is a high priority. Stainless steel sanitary tubing is used in such applications because it has high corrosion-resistance, doesn¡¯t tarnish, and is easy to keep clean.

254SMO made of high concentration of molybdenum, chromium and nitrogen has good resistance to pitting and crevice corrosion. Copper improves corrosion resistance in certain acids. In addition, 254SMO has good stress strength corrosion cracking properties due to its high content of nickel, chromium and molybdenum.

304 pipe offers superior resistance to intergranular corrosion following welding or stress relieving. Besides, the 304 and 304L type grades exhibit good machinability and excellent weld-ability characteristics with or without filler metals.

Because it is easily cleaned and sanitized, stainless steel pipe is also desired for applications involving food, beverages, and pharmaceutical applications.
