The Basic Types of Steel Metal

Posted on January 26, 2021 by gardencity

If you were to ask the American Iron and Steel Institute (AISI), they would tell you that steel can be categorized into four basic groups according to their individual chemical compositions. These four groups include 1) Carbon steel, 2) Alloy steel, 3) Stainless steel, and 4) Tool steel. All steel is composed of both iron and carbon, but vary in type depending on certain physical, chemical, and environmental properties, all of which are determined by the amount of carbon and any additional alloys.

Categories of Carbon Steel

Carbon steel can be further categorized into three groups, which are low carbon, medium carbon, and high carbon. Low carbon, also called mild steel, is one of the largest categories of carbon steel, and generally contains anywhere from 0.04% to 0.30% carbon content. Medium carbon generally contains anywhere from 0.31% to 0.60% carbon content, as well as a range of 0.60% to 1.65% of manganese content. High carbon steel is informally known as “carbon tool steel” and contains 0.61% to 1.50% carbon content. It is difficult to manipulate, and becomes very brittle when heat-treated.

Stainless Steel

Stainless steel contains added alloys that make is extremely resistant to corrosion in comparison to carbon and alloy steel. This is why it is commonly used in the medical/surgical industries, appliance industry, hardware manufacturing industry, food processing/handling industry, architectural industry, and more. It contains both carbon and iron, as mentioned before, but stainless steel generally contains other alloys as well, such as Chromium (Cr), Molybdenum (Mo), or Nickel (Ni).

Alloy Steel

Alloy steel also contains carbon, since all steel contains both carbon and iron. But alloy steel also contains a marginal number of additional elements, such as Nickle (Ni), Chromium (Cr), and Manganese (Mn). This type of steel is popular and commonly used due to their wide availability, economical costs, ease of processing, and quality mechanical properties. In comparison to carbon steel, alloy steel is more responsive to mechanical and heat treatments. Heated alloy steel comes in wither annealed or normalized.

Tool Steel

Tool steel is a general term to describe a variety of steels that retain high-hardness and abrasion-resistance properties. Specific applications for tool steel include stamping, extrusion, dies, cutting, mold-making, or impact applications such as hammering.

Stainless Steel is the Best Bet to Fending Off Corrosion

Stainless steel metal is something we are seeing more and more these days, everywhere you look. This special metal has a much higher chromium content, as well as a translucent coating that prevents discoloration and, you guessed it, corrosion. Stainless steel comes in many grades and finishes, all of which offer their own unique appeal or performance. Industries all across the nation benefit from stainless steel applications and assets, including food handling, food processing, medical instruments, hardware, appliances, architecture, and much more.

Compared to carbon steel, stainless steel has a much higher chromium content, so when exposed to conditions that would otherwise make it rust or corrode, it instead forms a passive coating of chromium oxide that prevents further deterioration. Not only does it not corrode and does not require a protective coating, it is also easy to clean and sterilize. See our blog, “The Difference Between Mild Steel and Stainless Steel” to learn why stainless steel materials are better for corrosion-resistant applications.

Additional Corrosion Resistant Alloys

Other corrosion-resistant alloys to consider for your building project include 316L austenitic stainless steel, alloy 22, and ZERON® 100. The most common applications for austenitic stainless steel include clad line pipe building, surface piping, and vessel cladding. One downfall is that it will pit of exposed to oxygen. Alloy 22 is typically used for conditions that require resistance to oxidizing acid chlorides, wet chlorine, mixtures containing nitric acid or oxidizing acids with chlorine ions, formic and acetic acids, ferric and cupric chlorides, brine, salt water, and even reducing acids like sulfuric acid and hydrochloric acid. ZERON® 100 is highly resistant to both pitting and corrosion in the presence of salt water, stress corrosion cracking, and similar elemental conditions.

Stainless Steel Components and Properties

Stainless steel, also known as inox or inox steel, is a man-made alloy that has a minimum of 10.5% chromium content and a maximum of 1.2% carbon content. Some of the most admired qualities of stainless steel is its resistance to staining, corrosion, and oxidation (rust). For this reason, it is often used in kitchens and food processing plants, as well as industries like medical, electrical, petrochemical, manufacturing, automotive, and more.

Benefits of Stainless Steel Metal

Stainless steel comes in many grades and finishes, all of which offer their own unique appeal or performance. Compared to carbon steel, stainless steel has a much higher chromium content, so when exposed to conditions that would otherwise make it rust or corrode, it instead forms a passive coating of chromium oxide that prevents further deterioration. Not only does it not corrode and does not require a protective coating, it is also easy to clean and sterilize.

Is Stainless Steel Magnetic or Not?

As mentioned, some types of stainless steel are magnetic, and others are not. Two particular factors must be true in order for stainless steel to be magnetic. First, it must contain iron. Some stainless steels contain iron, while others do not. You see, all metal can be categorized as either ferrous or non-ferrous. Ferrous metals contain iron, while non-ferrous metals do not. You can easily tell the difference between the two by simply using a magnet. If the magnet sticks, it is ferrous and contains iron; if it does not stick, it is non-ferrous and contains no iron. Second, stainless steel must have a crystal composition arranged in a ferritic or martensitic structure.

There are 3 types of magnetic stainless steel: ferritic, martensitic, and duplex. Non-magnetic stainless steel are alloys that have austenitic structures. This means they have higher quantities of austenite in them, which is what makes them non-magnetic. For instance, stainless steel grades like 304 and 316 retain high amounts of iron in their chemical composition, but their austenite structures renders them non-magnetic, or non-ferromagnetic.

Does Stainless Steel Have Magnetic Properties?

Posted on March 27, 2019 by gardencity

Stainless steel is one of the most sought-after metals in various industries all over the world for many reasons. One of the most valuable properties of stainless steel is its non-porous and thus, resistance to corrosion. You see, stainless steel contains a combination of alloys, including nickel, magnesium, chromium, copper, and iron. It is the chromium coating that gives stainless steel the ability to defend against rust and corrosion.

There are many more wonderful attributes of stainless steel; but what about magnetism? Is stainless steel magnetic? Many people want to know, but many people will tell you different answers. Continue reading to clear up the confusion for good.

Ferrous and Non-Ferrous Metals

Depending on the application, magnetic properties of a stainless steel commodity can have an effect on its performance. This is why you might care whether or not stainless steel is magnetic. Before you can understand the possible magnetic properties of stainless steel, you must first understand ferrous and non-ferrous metals, and the difference between the two.

Ferrous metals are metals, or alloys, that contain iron. The word “ferrous” literally translates to “iron”, making it easy to understand what a non-ferrous metal it. The term “non-ferrous” means “non-iron”, which means that non-ferrous metals are those that do not contain iron. Read our blog, “The Discerning Attributes of Ferrous and Non-Ferrous Metal” to understand these differences in better detail.

Stainless Steel and Magnetism

Getting back on topic, the test to identify ferrous and non-ferrous metals is through the use of magnets. Magnets are attracted to iron metal, which means a magnet will stick to something that contains iron, or is ferrous. If you stick a magnet to something, and it does not attract, the item likely does not contain iron, making it non-ferrous. So when you ask whether or not stainless steel is magnetic, you really might want to ask yourself is stainless steel ferrous or non-ferrous metal.

Most people assume stainless steel is magnetic because it contains iron in its chemical composition; but this is where the confusion comes into play. You see, although it contains iron, stainless steel isn’t always magnetic. In addition to containing iron to be magnetic, stainless steel must also be manufactured with a crystal structure arranged in a ferritic or martensitic structure. If it does not have both of these attributes, or mostly consists of of an austenite structure, it may not be magnetic.

✨ Check back with next month’s blog where we will discuss which types of stainless steel are magnetic, and how they compare to austenitic structures, which are not.
