Steel Square Bar

 Steel square bar was developed almost 4,000 years ago, steel has risen to the top of the construction and metalworking industries. Early versions of this iron alloy weren’t quite as strong and durable as their modern counterparts, but the last 150 years or so have brought about numerous advancements in how steel is made. Today, it’s a highly sought-after metal for a wide range of uses with cold and hot rolled square bar being among the common choices.

Understanding the Different Types of Steel
If you’re searching for a steel supplier, it’s important to understand that different types of steel are available. Each one has specific properties and is recommended for various applications. Not all of them work well for all situations.

• Alloy Steel. Steel alloys are composed of iron and other elements, such as aluminum, copper, nickel, and titanium. It’s available in steel plates and tubes as well as flat, round, hexagonal, and square bars.
  
  
• Carbon Steel. Whereas alloy steel contains a range of metals, carbon steel is made of iron and small amounts of carbon. Mild carbon steel is composed of up to 0.30 percent carbon. Medium carbon steel contains 0.31 to 0.60 percent carbon while high carbon steel is comprised of 0.61 to 1.5 percent carbon.
  
  
• Stainless Steel. Another type of alloy, stainless steel is made up of iron and chromium, molybdenum, or nickel. It’s more resistant to corrosion than other types of steel and comes in many shapes and forms.
  
  
• Tool Steel. Tool steel is hard and highly resistant to constant wear. It’s often used to make impact tools, dies, and cutting implements among other items.

Each of these basic types of steel is divided into several sub-categories. Aside from that, the different types of steel are further broken down into numerous additional classifications based on certain factors. Because of their diverse uses, cold rolled and hot rolled steel square bar are often the best choices for many applications.

Discussing the Differences between Hot Rolled and Cold Finished Steel Square Bar
Hot rolled steel square bar is created by heating iron ore to high temperatures and pressing it into shape using a roller. Being heated and formed makes this type of steel simpler to work with than some other varieties. Still, it doesn’t lose its strength, hardness, and resistance in the process. Hot rolled steel bar can be used in construction and welding as well as to create artwork and ornamental architectural elements.
Cold finished steel square bar starts off as hot rolled steel, but it undergoes additional processing. After being formed using high heat, the steel is drawn through dies for further shaping. Cold rolled steel has a smoother surface and sharper edges than hot rolled, and it often has higher tensile strength than its less-processed counterpart. This type of low carbon steel is typically used in machining.

Looking into Steel Grades
Steel comes in a long list of grades, and each type is assessed on a different grading system. For hot rolled steel bar, the most commonly used grade is A-36. A-36 steel offers high tensile strength, takes welding well, and is suitable for machining and forming.
​
When it comes to cold finished steel bar, C-1018 is a highly recommended alternative. It’s a low carbon steel with higher amounts of manganese than some other steels in its class. It’s considered an all-purpose steel because it’s appropriate for many uses.

Overall
If you’re looking for steel bar, hot rolled and cold finished are the primary choices. Each one has its own set of benefits and applications with the main differences between the two being their processing methods. Though several grades and types are available for both, A-36 hot rolled steel and C-1018 cold finished steel are the most popular options. Both are available in a range of sizes, so they can be adapted for several uses.
