If you’re being technical, steel that falls into any of these four group classifications is an alloy, but that’s not what I’m talking about right here. “Alloy steel” is different from “steel alloys.” So, what is alloy steel? Alloy steel is steel that includes about 5% alloying elements in its composition. These alloying elements can include manganese, chromium, vanadium, nickel, and tungsten. The addition of alloying elements increases overall machinability and corrosion resistance.
Alloy steel is most commonly used to manufacture pipes, especially pipes for energy-related applications. It’s also used in the manufacturing of heating elements in appliances like toasters, silverware, pots and pans, and corrosion-resistant containers.
I hope you have a better understanding of steel in general and the four groups steel is often broken into: stainless steel, carbon steel, tool steel, and alloy steel. If you’d like to learn more about stainless steel
Carbon steel and stainless steel have the same basic ingredients of iron and carbon, but where their composition differs is in alloy content. Carbon steel has under 10.5 percent alloy content. It’s common to see carbon steel broken down into three subcategories: low carbon steel (0.03-0.15% carbon), medium carbon steel (0.25%-0.50% carbon), and high carbon steel (0.55%-1.10% carbon).
As the percentage of carbon increases, the steel becomes harder and more difficult to bend or weld. Low carbon steels are more commonly used due to having lower production costs, greater ductility, and increased ease of use in manufacturing. Low carbon steels are more likely to deform under stress, while high carbon steels are more conducive to breaking under pressure. Low carbon steels are commonly used in auto body panels, bolts, fixtures, seamless tubes, and steel plate.
Stainless steel is 100 percent recyclable, easy to sterilize, and used in many applications. In fact, ordinary citizens interact with products made of stainless steel on a daily basis. Whether we're in the kitchen, on the road, at the doctor's office, or in our buildings, stainless steel is there too. Today, I'll be covering some of the common traits, products, and applications of this versatile metal. Hit save when you are done.
Unlike ordinary steel, stainless steel isn't prone to corrosion, rusting, or staining with exposure to water. But this isn't to say it's completely stain-proof. In areas with low oxygen, high salinity, or poor air circulation, stainless steel is vulnerable to staining.

Like ordinary steel, stainless steel is a poor conductor of electricity. For comparison, its electrical conductivity is much lower than that of copper.
Tool steels have a carbon content between 0.5% and 1.5%. Tool steel contains other additives, including tungsten, chromium, vanadium, and molybdenum. Tool steels are known for their hardness and their ability to hold a cutting edge at elevated temperatures. This, combined with being resistant to wear and deformation, makes tool steel perfectly suited for use in machining and tool making.
Die steel is made with plain steel or alloy steel. It is used for the manufacturing of tools, which can be used for multiple purposes, including cutting, stamping, shearing, punching, chipping, etc. There are many different types of die steels that are present in the market. Depending on the way, the die steel is manufactured, the types of die steels include: - Hot work Steel : H-11, H13, DB6, P20, ( 2343, 2344, 2714, 2378) - Cold work steels : D2 , D3, O1 ( 2379 , 2080 ) - Shock resistant and low carbon tool steel - High speed die steel M2 , M35, T1 - Plastic mold tool steel P20 , P20 +Ni ( 2311, 2738 ) To increase the level of hardness of tool steels, various elements with alloying properties like chromium, vanadium, molybdenum, manganese and tungsten are added to the plain or alloy steel. These added elements make the plain steel harder and gives it stable carbides.
