Do you know steel grades?

We all know that choosing steel pipes such as black steel pipe for a project plays a significant role in construction industry. Do you know how to choose materials? What is steel grades? Actually, steel grades are a collection which include various steel classifications for defining both the type of steel and the process furnace. There are two types of grading system for steels, one is the Society of Automotive Engineers the other is American Iron and Steel Institute standards. In the UK or matched to British, the AISI standards are widely used. How to notify steel type? As a matter of fact, each classification code for a steel type is usually a four-digit number or alpha-numeric code. Of course, letter is also necessary for indication. For example, “E” designates an electric arc furnace, “C” indicates an electric arc.

There are lots of steel grades manufactured in industry, so we need to draw a steel grades chart to organize these various types of the metal. What is the meaning of this action? This is because steel vary in physical and chemical properties when mixed with other compounds. For example, carbon, chromium and manganese are involved in hot rolled steel pipe. Other elements are often used as well such as boron, nickel and silicon. We will know the ingredient percentages in the steel through AISI. We can take grade 1018 as an example, containing around 0.15% carbon, 0.75% manganese as well as 0.030% phosphorus.

In the US, cold rolled steel pipe grades start with a prefix of two numbers, either 10 or 15, which can be divided into plain carbon steel, steel with sulfur content and phosphorus content as well. These steel grades then progress in the AISI/SAE system numerically. However, all European coding schemes are not familiar to four digit designation.

International standardization of steel grades for all kinds of steel, ranging from structural steel to mild steel grades usually incorporates charts. The charts compare with different regional standards including US standards, Europe in general. Steel pipe manufacturers should understand these steel grades. Regional difference is a significant factor for steel grades, a steel ranging on such a chart would be carbon steel 1018 in the US, which is C15D in Europe. It is none the less an idea to which some people cling, which is harmful to choose desired products. Do you have any questions about steel grades? Hope to answer your questions.
