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.

Stainless steel flange is also called flange plate. Flanges are the parts that connect pipes to each other and are connected to pipe ends. Flange connection or flange joint refers to the detachable connection of a group of combined sealing structures connected by flanges, gaskets and bolts.

ASTM A403 WP316 is the standard molybdenum-bearing grade, second in importance to 304 amongst the austenitic stainless steels. The molybdenum gives 316 better overall corrosion resistant properties than Grade 304, particularly higher resistance to pitting and crevice corrosion in chloride 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.

While the chemistry of Stainless Steel 304L Flanges is similar to grade 304, there are some changes done to its chemical composition. The modification in the chemistry of grade 304L improves its properties like weldability.

300 series grade stainless steel is a chromium-nickel alloy that is manufactured into a range of products including stainless steel tubes and steel pipes. Both 304 and 316 steel pipe is durable enough to maintain its strength at high temperatures, resist corrosion, and is easy to maintain. The choice between material is highly dependent upon how you will use the pipe and the environment in which the pipe will be installed.

Alloy 309/309S (UNS S30900/S30908) Austenitic stainless steels are typically used in high temperature applications. Its high chromium and nickel content provides comparable corrosion resistance to ordinary austenitic alloy 304, excellent oxidation resistance and a greater percentage of room temperature strength retention.

Heat treatment does not affect 254 Smo Stainless Steel Pipe they can only be hardened via cold reduction. SMO 254 Erw Tubes have a great influencing potential and ductility at ambient and sub-zero temperatures.

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.

There are hundreds of different grades of stainless steel on the market. Each of these unique stainless steel formulations provides a degree of corrosion resistance that exceeds that of ordinary steel. The existence of these stainless steel variants can cause some confusion – especially when the two stainless steel alloys are nearly identical in name and formula. This is the case with 304 and 304L stainless steel.

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.
