Benefits of Stainless Steel
 

Corrosion resistance

All stainless steels exhibit high resistance to corrosion, making them suitable for a wide range of environments. Low alloyed grades resist corrosion in atmospheric conditions; highly alloyed grades can resist corrosion in most acids, alkaline solutions, and chloride-bearing environments, even at elevated temperatures and pressures.

High and low-temperature resistance

Some grades will resist scaling and maintain high strength at very high temperatures, while others demonstrate exceptional toughness at cryogenic conditions.

Ease of fabrication

Stainless steel is highly versatile and can be easily cut, welded, formed, machined, and fabricated, allowing for efficient manufacturing processes.

Strength

The cold work hardening properties of many stainless steels can enable design optimisation by reducing material thickness, weight, and associated costs. Other stainless steels may be heat treated to produce very high-strength components.

Aesthetic appeal

Stainless steel is available in many surface finishes. It is easily and simply maintained resulting in a high quality, pleasing appearance.

Hygienic properties

Stainless steel's cleanability makes it the first choice in environments where hygiene is critical, such as hospitals, kitchens, and food and pharmaceutical processing facilities.

Application of Stainless Steel
 

Food and catering
Stainless steel is commonly seen as kitchen accessories, cutlery, and cookware. From knife blades with sharp edges to molded shapes like cookers, grills, sinks, and saucepans- the presence of stainless steel is essential. It’s also used as a finish for refrigerators, countertops, and dishwashers.

 

Offshore technology
In offshore technology, stainless steel is mainly used in the pipework. They are used to transport hydrocarbons, petrochemicals, etc. for seawater systems. They are often the best choice for offshore systems given their resistance to the corrosive effects of seawater.

 

Seawater desalination plants
Stainless steel’s great mechanical properties make it an essential material for seawater reverse osmosis units (SWRO).

 

Chemical industry
Chemical plants expose metals and equipment to an extremely harsh environment. Stainless steel offers the best solution to withstand corrosion elements.

 

Bridges
Duplex stainless steels, a recent family of stainless steel alloys, are becoming increasingly popular in bridges and other engineering structures as these steels are typically twice as strong as ferritic alloys. Because of their increased strength, less material is needed, thus becoming more cost and weight-efficient.

 

Storage tanks
Stainless steel tanks are regularly used to hold corrosive substances such as chemicals, gases, and many other bulk materials, including food and water. It doesn’t add any flavor or smell to foods and water, which is another advantage.

FAQ

 

Q: How does stainless steel resist corrosion?

A: Stainless steel's corrosion resistance comes from its passive layer, a micro-thin, chromium-rich oxide film that forms spontaneously when the metal is exposed to oxygen. This invisible film acts as a barrier, protecting the underlying iron from oxidizing. If the passive layer is damaged, it can naturally self-repair, provided there is enough oxygen present in the environment.

Q: What are the main families of stainless steel?

A: Stainless steel is broadly categorized into five main families based on their crystalline structure: austenitic, ferritic, martensitic, duplex, and precipitation-hardening. Austenitic types, such as the common 304 and 316 grades, are known for excellent corrosion resistance and ductility. Ferritic steels are magnetic and offer good corrosion resistance at a lower cost, while martensitic steels are prized for their hardness. Duplex and precipitation-hardening steels combine properties for higher strength and corrosion resistance.

Q: What is the difference between 304 and 316 stainless steel?

A: The primary difference is the addition of molybdenum in 316 stainless steel, which significantly improves its resistance to corrosion, particularly against chlorides and pitting. This makes 316 the preferred choice for marine environments, coastal areas, and chemical processing. In contrast, 304 stainless steel is a general-purpose, economical grade suitable for a wide range of applications, including most kitchen equipment.

Q: Why are some types of stainless steel magnetic and others not?

A: Whether stainless steel is magnetic or not depends on its microstructure. Ferritic and martensitic stainless steels have a body-centered cubic crystalline structure that makes them magnetic. Austenitic stainless steels, which are more common and contain higher levels of nickel, are generally non-magnetic in their annealed state. However, they can become slightly magnetic when heavily cold worked.

Q: What does the marking 18/8 or 18/10 on stainless steel mean?

A: The numbers 18/8 and 18/10 refer to the chromium and nickel content, respectively. The first number, 18, indicates that the steel contains approximately 18% chromium. The second number denotes the nickel content, with 18/8 having about 8% nickel and 18/10 having about 10%. The higher nickel content in 18/10 provides slightly better corrosion resistance and a more lustrous finish, often used in high-quality cutlery and cookware.

Q: Is stainless steel recyclable?

A: Yes, stainless steel is 100% recyclable and is one of the most recycled materials in the world. It can be melted down and repurposed indefinitely without losing its quality or properties. Recycling stainless steel is more energy-efficient than producing it from raw materials, which significantly reduces carbon emissions and conserves natural resources.
