Excellent corrosion resistance

Stainless Steel 316 is renowned for its excellent corrosion resistance, making it ideal for use in applications where the material may be exposed to harsh environments or corrosive substances.


High strength and durability

With a tensile strength of up to 579 MPa (84 ksi) and a yield strength of up to 290 MPa (42 ksi), Stainless Steel 316 can withstand high levels of stress and deformation without losing its shape or structural integrity.



The addition of molybdenum to the alloy provides superior corrosion resistance in chloride-rich environments, such as marine and coastal environments.

316L Stainless Steel is an austenitic alloy that has gained an excellent reputation in the world of engineering and industry for its versatility and corrosion resistance. Composed mainly of chromium, nickel and molybdenum, this material is widely used in a wide range of industries due to its exceptional mechanical and chemical properties.


Excellent corrosion resistance: One of the distinguishing features of Stainless Steel 316L is its extraordinary resistance to corrosion. Thanks to the presence of elements such as nickel and molybdenum, this alloy offers superior protection against corrosive agents compared to other types of stainless steel. This property makes it particularly suitable for marine and coastal environments, where salty air and constant humidity pose a challenge to the materials.

High strength and durability: In addition to its corrosion resistance, 316L Steel boasts extraordinary strength and durability. It is capable of maintaining its structural integrity even under the most demanding conditions, providing a reliable solution for applications requiring strength and longevity. This characteristic makes it a valuable material in industries operating in extreme environmental conditions or subject to intense mechanical stress.

Greater pitting and crevice corrosion resistance than 304 stainless: Inox 316L offers greater resistance to pitting and crevice corrosion than its counterpart, 304 stainless. This makes it a preferred choice in critical industries such as chemical, food and marine, where corrosion resistance is critical to the safety and reliability of structures and equipment.

Ideal for sectors such as the marine, food and chemical industries: Thanks to its exceptional properties, this stainless steel is widely used in a wide range of industrial and commercial sectors. It is particularly suitable for the marine industry, where corrosion resistance is essential for the durability of structures exposed to environmental agents. It is also used in the food industry, where its corrosion resistance and ease of cleaning make it ideal for use in processing and storage equipment. Finally, its use in the chemical industry is essential for its resistance to corrosive chemicals and its reliability in critical environments.


It may be subject to stress corrosion cracking in certain environments: Although 316L Steel is generally known for its corrosion resistance, it is important to consider that it may be subject to stress corrosion cracking in certain environments. This phenomenon can occur under specific conditions where combinations of mechanical stresses and aggressive chemicals are present, such as in environments with high concentrations of chlorides or other corrosive agents. Therefore, it is essential to conduct a careful assessment of the usage environment and, if necessary, take additional protective measures to prevent structural deterioration.

Not suitable for very high temperature applications: Another important consideration regarding Stainless Steel 316L is its suitability for very high temperature applications. Despite its excellent performance at moderate temperatures, it may not be the most suitable material for applications requiring high operating temperatures. Under such extreme conditions, materials with superior thermal properties may be required that can maintain their structural integrity and mechanical performance even at higher temperatures.


Chemical sector: Inox 316L is a highly reliable and versatile material in the chemical sector. Its resistance to corrosive chemicals makes it valuable for a wide range of applications where aggressive chemicals are required. It is successfully employed in chemical manufacturing installations, where it is used for the construction of reactors, tanks, piping and other components that must withstand the corrosive action of aggressive chemicals. Its ability to maintain its structural integrity makes it an ideal choice for ensuring the safety and reliability of industrial operations.

Pharmaceutical sector: In the pharmaceutical sector, where hygiene and sterilisation are of vital importance, Stainless Steel 316L is a preferred material for the production of equipment and containers. Its smooth, non-porous surface, combined with its resistance to corrosion and rust, makes it easily cleanable and resistant to bacterial growth, making it ideal for use in sanitary environments. It is commonly used in the manufacture of storage tanks, chemical transport vessels, support structures and other critical equipment for the production of drugs and pharmaceuticals. Its ability to satisfy the most stringent hygiene standards makes it a reliable choice for ensuring the safety and quality of pharmaceutical products for human consumers.

Marine industry: This alloy is widely used in the marine industry for its exceptional resistance to saltwater corrosion. Its anti-corrosive properties make it ideal for components exposed to the aggressive agents of the sea, such as port facilities, fishing equipment and offshore installations. Its ability to maintain structural integrity even in extremely corrosive environments makes it an essential material for ensuring the durability of naval infrastructure and safe offshore operations.

Food industry: In the food industry, this stainless steel is an ideal choice for processing and storage equipment due to its hygienic properties and ease of cleaning. Its smooth, non-porous surface prevents the accumulation of bacteria and food residues, reducing the risk of contamination and ensuring the safety of food products. It is widely used in the production of food processing equipment such as storage tanks, cooking utensils and packaging equipment, helping to maintain the highest standards of hygiene and safety.


In conclusion, 316L Stainless Steel is an excellent solution for a wide range of industrial and commercial applications due to its exceptional mechanical and chemical properties. Its well-established reputation in the world of engineering and industry is justified by its versatility and outstanding corrosion resistance, making it a first-rate material for many sectors.

Its excellent corrosion resistance, combined with remarkable durability and structural strength, makes it ideal for marine, food, chemical and many other industrial applications. However, it is important to consider some potential disadvantages, such as the possibility of stress corrosion cracking in certain environments and the limitation in high temperature applications.

Despite these points, 316L Stainless Steel continues to be the best choice for many critical applications, ensuring reliability, safety and long-lasting performance. With its combination of superior performance and versatility of use, it remains an essential material for modern industry.
