In the CNC Machining field, we usually find raw material requirements with some special conditions on drawing. In the material specification, you will find some symbols and letters. These symbols and letters are simple in writing but usually difficult to understand if you are not professional on the type of raw materials. In this post, let’s take 11SMn30+C for example to explain the symbols and letters.
Do you know what is +C in11SMn30+C?
This +C means the raw material 11SMn30 is required in cold-drawn condition. We all know raw materials in different heat treatment conditions differ much in performance. To understand the raw materials correctly, we must pay attention to every single letter. So right understanding of such +C is very important.
Normally, you may take much time to search from Google Search Engineer before getting the right answer to +C. However, here we would like to share with you the right answer directly and more details about heat treatment conditions. Such a problem would be solved just in a second. It would save much time for you to understand what the designer exactly needs on raw material. Feel free to save it. Hope it’s helpful to you in a way. Any more questions, don’t hesitate to let us know.
