Planning and Executing Construction and Contracting Projects: Tips for Consumers

Welcome to my blog. My name is Deborah. About 15 years ago, I bought an old home. We worked with several contractors to rehabilitate it, but ultimately, the foundation simply wasn't stable enough, and we had to tear it down. After that, we worked with a construction crew to build a home from the ground up. The experience was exciting and challenging, and I learned a lot through that process. I want to share construction and contracting facts and information with others so I decided to start this blog. I hope that you like the results, and I thank you for reading. Enjoy!

Introduction To Steel: 2 Frequiently Asked Questions

by Samantha Russell

Steel is among the most commonly used building materials in the construction industry today. This can be partly attributed to its versatility as well as its ready availability.

Having emphasized the importance of steel, this article proceeds to provide answers to two common questions about the mentioned building material. Information herein would be most useful to trainee metal fabrication specialists.

How Is Steel Classified?

Classification of steel can be done using a wide range of parameters. These parameters include chemical composition, the shape/form of the metal and the type of finishing used on it.  

Using the shape/form of the metal as the parameter for classification gives rise to different types of steel including rod, sheet, bar, and structural steel. When the type of finishing is used, categories such as hot rolled, cold drawn and cold rolled result.

Chemical composition of the metal is the mostly widely accepted parameter used in the classification of steel. Using this parameter gives rise to four main classes of steel. These are carbon steel, stainless steel, alloy steel and tool steel.

Which Applications Are The Main Classes Of Steel Commonly Used For?

Thanks to the difference in their chemical composition, the four main classes of steel have different characteristics and different properties. For this reason, each class of steel will be more suitable than the others for different types of applications.

Tool steel is known for its remarkable resistance to abrasion and for its high-hardness. Examples of applications for which tool steel is suitable include the extrusion of dies, mold-making and the fabrication of high-impact tools such as hammers.

Steel is mainly made up of carbon and iron. Metals that fall under the category of alloy steels must be made up of carbon, iron and at least one other metal (an alloying element). Common alloying elements include nickel and manganese. Alloy steels are preferred for use in industrial applications because they're affordable, readily available and easy to process.

Stainless steel is also commonly used for industrial applications. It is a commonly used in the handling and processing of food items, in the fabrication of various appliances used on a daily basis (e.g. cutlery) and in the fabrication of medical equipment (e.g. stethoscopes). Various alloys are added to stainless steel so as to make it more resistant to corrosion than carbon steel and alloy steels. Chromium and molybdenum are common alloying elements found in stainless steel.
