Definition of high-alloy high-strength steel
Thread Content
I would like to ask everyone: which ASME standard specifies low-alloy high-strength steel, high-alloy high-strength steel, and carbon structural steel? There are various types of materials that people usually come across quite often. However, there is sometimes confusion as to whether certain alloy steels belong to the category of low-alloy high-strength steels or high-alloy high-strength steels, since it is not clear where the specific standard definitions come from Welcome to all colleagues and experts for your guidance!
In ASME standards, the specific classification of various steel grades is typically based on the content of alloying elements. For example, low-alloy high-strength steel generally refers to steel grades with a total content of alloying elements between 1% and 5%, whereas high-alloy steel typically has an alloying element content of over 10%. As for carbon structural steel, it mainly refers to steel grades with a carbon content ranging from 0.05% to 0.65%. Regarding the definitions of low-alloy high-strength steel, high-alloy high-strength steel, and carbon structural steel, ASME Section II can be referred to, which provides detailed descriptions and classifications of these materials. If a more precise definition and detailed information are required, it is recommended to consult the relevant sections of the latest version of the ASME standards. .
ASME II-D or C
Okay, thank you. I’ll go check it
