Stainless steel is an alloy of iron that is resistant to rusting and corrosion. 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
Completely and infinitely recyclable, stainless steel is the ¡°green material¡± par excellence. In fact, within the construction sector, its actual recovery rate is close to 100%.
Stainless steel is also environmentally neutral and inert, and its longevity ensures it meets the needs of sustainable construction. Furthermore, it does not leach compounds that could modify its composition when in contact with elements like water.
Stainless steel must contain at least 10.5 percent chromium. Depending on the grade, it may contain much higher chromium levels, and additional alloying ingredients like molybdenum, nickel, titanium, aluminum, copper, nitrogen, phosphorous or selenium.
In addition to these environmental benefits, stainless steel is also aesthetically appealing, extremely hygienic, easy to maintain, highly durable and offers a wide variety of aspects. As a result, stainless steel can be found in many everyday objects. It also plays a prominent role in an array of industries, including energy, transportation, building, research, medicine, food and logistics.

926 is an austenitic stainless steel alloy with a chemical composition similar to alloy 904L with 0.2% nitrogen and 6.5% molybdenum. Molybdenum and nitrogen contents significantly improve pitting and crevice corrosion resistance in halide media. At the same time, nickel and nitrogen not only ensure the stability of the metallographic phase, but also reduce the tendency of intergranular segregation during thermal process or welding process better than nitrogen content. Nickel alloy. 926 has exceptional corrosion resistance in chloride ion media due to its excellent localized corrosion resistance and 25% nickel alloy content.

The alloy can be machined at satisfactory speeds with machine tools commonly used in the industry. Generally, cold drawn or cold drawn stress relief materials are recommended for the best machinability and smoothest finish.

The connection between two pipes can be directly welded together, but it is difficult to connect together without welding. When the connection part have problems, it will be hard to repair. The same problem also happened between pipe and valve connection.

The chemical balance allows the alloy to exhibit excellent resistance to carburization, oxidation and nitriding atmospheres. 800HT will not become embrittled even after long periods of usage in the 1200-1600 deg F range where many stainless steels become brittle. Excellent cold forming characteristics typically associated with the nickel-chromium alloys are exhibited with 800HT. When cold formed extensively the grain size produces a visibly undulated surface called “orange peel”. 800HT can be welded by the common techniques used on stainless steels.

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).

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.
