Germany Standard Steel Numbering Method
The German standard steel numbering system, developed by Germany in the 1960s, has been widely adopted in the industry due to its simple, effective and flexible character. The steel numbering system defines each type of steel as a four-digit code, which is used to identify the different chemical compositions of steel.
The first two digits of the steel number stand for the material type. For example, 41 indicates that the material is an unalloyed steel, while 42 stands for an alloyed steel. The second two digit denote the content of important alloying elements. For example, the number 07 stands for a steel containing a minimum of 7% Chromium, while the number 11 indicates that the steel contains 11% or more Chromium. Furthermore, the numbers 01-99 are used to differentiate steel grades with a similar grade name or a similar level of material performance.
When looking at the steel numbering system, it is possible to make some generalizations about the steel. For instance, it is easy to determine whether the steel is an alloy steel or not. Furthermore, it is also easy to identify if the steel is high-alloy or low-alloy. For example, any steel that begins with 44 is considered high-alloy, while those beginning with 43 are low-alloy steels. The steel numbering system also makes it possible to make some inferences about the chemical composition of the steel.
One of the main advantages of the steel numbering system is its flexibility. For example, it can be easily modified to accommodate changes in the steel production process. As new types of steel are developed, the standard steel numbering system can easily be adapted to include the new steel grades and types. Furthermore, the numbering system can be adjusted to account for changes in the grade or grade designations of the different steel types. In this way, the system has the advantage of being able to accommodate the ever-changing needs of the steel industry.
In addition to its flexibility, the steel numbering system is also very easy to use. All that is needed for the identification of steel types is the four-digit code of the steel. Furthermore, the system does not require any special knowledge and can be used by anyone. This makes the system an ideal choice for steelmakers, who often need to quickly and accurately identify steel grades.
Overall, the German standard steel numbering system is an effective and efficient way of identifying steel grades and types. It is simple, easy to use and flexible, while also providing a reliable and standard method of identification.
