The increased nickel content and the inclusion of molybdenum makes grade 316 stainless steel a bit costlier than grade 304 per ounce of material. But where grade 316 stainless proves superior is its increased corrosion resistance¡ªparticularly against chlorides and chlorinated solutions. This makes grade 316 stainless particularly desirable for applications where exposure to salt or other powerful corrosives is an issue.

There is more carbon in 316 stainless steel than 316L. This is easy to remember because the L stands for “low”. But even with the lower carbon content, 316L is very similar to 316 in almost every way. Costs are very similar, and both are durable, corrosion-resistant, and a good choice for high-stress situations.

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.

La tuberia 254 SMO a menudo se usa como reemplazo de componentes criticos de estructuras grandes donde el tipo 316L o 317L falla debido a picaduras o agrietamiento por corrosion bajo tension de cloruro, la tuberia 254 SMO puede soportar los mismos entornos corrosivos.

It is much more resistant to sulfuric acid, chloride, bromide, iodide and fatty acid solutions at high temperatures. The manufacture of certain pharmaceuticals requires the use of molybdenum-containing stainless steel to avoid excessive metal contamination.

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.

The lower carbon content of 304L alloy helps to minimize/eliminate carbide precipitation during welding. This allows 304L stainless steel to be used “as welded”, even in severely corrosive environments. If you use standard 304 stainless steel in the same way, it will degrade faster at welded joints.

304 also contains 8-10.5% nickel (Ni). It is added to make the austenite structure more stable at room temperature. Nickel also improves high temperature oxidation resistance, making the steel resistant to stress corrosion cracking. Where the steel is to be stretch formed, a lower percentage (8%) of nickel should be chosen. Higher percentages are better (9% or more) if the steel is to be deep drawn.

316L is a better choice as 316 is more susceptible to weld corrosion than 316L (corrosion within the weld). However, 316 can be annealed to resist weld decay. 316L is also a premium stainless steel for high temperature, high corrosion applications, which is why it is so popular in architectural and marine projects.

304L stainless pipe has slightly lower mechanical properties than standard 304 grades, but is still widely used due to its versatility. Like Type 304 stainless steel, it is commonly used in beer brewing and winemaking, but is also used outside of the food industry, such as chemical containers, mining and construction. It is ideal for metal parts such as nuts and bolts exposed to salt water.

Alloy 254 SMO contains high levels of chromium, molybdenum and nitrogen and is often used in high chloride environments such as brackish water, sea water, pulp mill bleach plants and other chloride process streams.
