Stainless Steel

The Most Popular Types of Stainless Steel

Over the last century, stainless steel has risen to become one of the most popular and widely used types of alloys, in both the developed and developing world. Stainless steel is used in many different applications, from large constructions, such as bridges and buildings, to the finest tuned surgical instruments and machine parts.

If you intend to use stainless steel for industrial applications, then you need to consider the four popular types of steels available today. Under the following four categories of stainless steels, there are more than 150 different grades to choose from. It is because of this that you should seek professional advice from industry experts, such as Stalcor, before investing in a large quantity of stainless steel for any specific project. Our experts are always at hand to provide you with all of the information that you will need to make informed purchasing decisions.

Austenitic Stainless Steel

This type of alloy is the most extensively used throughout various industries. Its main components, aside from iron, are nickel, nitrogen and manganese.

Ferritic Stainless Steel

Aside from iron, chromium also forms part of ferritic stainless steel’s make-up. Its carbon concentration is usually less than 0.1%.

Duplex Stainless Steel

This type of stainless steel’s name is derived from its structure being a mix of ferritic and austenitic. In principle, the two structures are utilised in equal measures, but there can be deviations of as much as 10% either way.

Martensitic Stainless Steel

This type of stainless steel features high chromium levels and a carbon concentration that does not exceed 1%. It is very strong, but not as resistant to corrosion as most of its counterparts.

These are four of the main types of stainless steels available on the market. If you feel overwhelmed by the choices available, there is no need to fret. Stalcor brings more than a decade of experience to the industry and offers our expertise to the benefit of our customers.

Why Use Stainless Steel in Industry Applications?

Stainless steel is one of the strongest and most durable alloys around. If you are still unsure, however, whether to invest a little more to get the best material for your factory equipment, food processing plant or dairy farm, or to use the material in the making of products to sell to customers in the above industries, read on and then make a final decision. 

Corrosion Resistance 

We mention this first because stainless steel can be used in various applications ranging from alkaline chemicals to acids, oils, water and chlorine without corroding. With such then it is the perfect material for usage in projects where you will want to avoid a situation of the chemicals changing the properties of the equipment. Corrosion resistance also means lower maintenance, longevity and of course, better product storage or handling. 

Excellent Hygiene Character 

With the material so easy to clean and maintain, better hygiene practices can be followed, which is important for any company operating within the food and beverages industry. In addition, the surface has a distinct hygienic appearance. 

Numerous Types 

Stainless steel comes in various forms, thickness, flexibility, and strength profiles. This makes it a rather versatile material in the manufacturing industry. 


Since the material is so strong, you can use thinner walled material in your engineering processes. This evidently means lower production cost and thus higher profit in addition to less waste production.

Easy to Work With

The material can be formed through various processes including cutting, welding, rolling and machining. It can also be formed using cold or high temperature based methods.

Superior Temperature Characteristics

The material can withstand extremely warm or cold temperatures and can therefore be used in just about any region of the world. It does not lose its strength in low temperature environments, unlike many other types of materials.

Low Environmental Footprint 

Concerned about your company’s compliance with international environmental risk management standards? Want to ensure that your environmental footprint can be minimised? Then stainless steel is your answer. Less than six percent of the stainless steel used today comes from mined resources. Almost all the material is recycled.

Value for Money

If you are looking for a material that can last for years to come, is low in maintenance, looks great, and is hygienic and corrosion resistant, then stainless steel provides the best value for money. Making products from this versatile material is cost-effective and will mean that you can market your products based on the excellent qualities of stainless steel.

Stainless Steel or Aluminium

One of the most important decisions you can make when purchasing stainless steel sheet metal is to look for the correct grade or finish metal. It isn’t that difficult a task when you know what you need to look for. Stainless steel’s name derives from its high resistance properties to blemishes and marks and its myriad of applications. This alloy’s properties are consistent and won’t require any special coating or surface protection in order to retain its shine. The stain resistant properties of the metal isn’t only limited to its surface. Should the metal become damaged, exposed surfaces will still be able to maintain its incredible properties. The metal will never lose its colour nor will it ever corrode, as other types of metal might.

Stainless steel’s different grades, alloys and forms provide the correct material for applications where there is an incredible level of robustness that is required. Its surface is entirely resistant to rust and the corrosive effect that most chemicals have on metals. There are different types and grades of stainless steel ideal for different applications. The 300 series is perhaps the most common type of stainless steel on the market. This popular steel is extremely ductile and offers a high resistance to corrosion. It is also easily welded, and this perhaps speaks to its continued popularity. Should you need a metal that will have to endure heavy duty work, it will be better to consider using types 304 and 316. These types of metals are frequently used in food and chemical processing industries and for the making of countertops and backsplashes.

You will also find that stainless steel comes available in various kinds of surface finishes. There are those that have been designed and manufactured to meet specific purposes, while there are those that are for mere decoration purposes. The different finishes are created by the application of varying treatments and a varying degree of nickel and chromium in the alloy. Certain types might also be provided with magnetic properties.

Thickness and Flexibility of Stainless Steel

Thanks to the technology of trim mouldings, it is now possible to eliminate unsightly edges in the material. The metal won’t look as polished if the edges aren’t trimmed properly. The trim moulding will also make it far easier to use and handle the material during the installation process.

Other factors to consider when buying stainless steel sheet metal are the flexibility and thickness of the metal. It is necessary to select metal sheeting that will be best suited for its purpose and application. Its thickness is normally listed in decimals. This is so as to make it easier for buyers to grasp it quickly. At times it might be necessary to cover the metal with PVC film during transportation in order to protect its surface from any possible scratching.
