- There are a lot more materials available, but due to the size limit of this web page, we could only make a list of the most frequently used ones.
 
- Also due to the size limit of this web page, the mechanical properties and some detail requirements of the composition could not be included in this list.
 
- Materials could have different names when the form/utility is changed. For example, SS304 could be specified as CF-8 when used for casting processes.
 
- Any further information, please contact Spectro Analysis Co.,Ltd., we will have our metallurgist to answer your questions.

 


 

Metal Standard Conversion
 
Material Standard Conversion ASTM / DIN / JIS / BS / GB China / ISO / NF:
Below is a conversion table of the most frequently used materials in different national standards, as to the composition of the materials, please refer to “Metal Material Composition”.
 
- Materials in different national standards might be slightly different in some detail compositions. It would be better to specify which standard it is conforming to in the quotation and the purchase order.
 
- Due to the size limit of this web page, some of the materials could not be listed here. For example, some sheet metal stamping materials CRS plates, Galvanized plates..If you would need more information, please contact Spectro Analysis Co.,Ltd.
 
- Same material but in different shape or form might have different material numbers or names.
 
- The national standard of USA is ANSI, however ASTM is more frequently used

Steel Hardness Conversion
 

Below is a conversion table for the hardness of the steel.

The values listed are for reference only. There are some parameters that could change the conversion. For example, the HV is only testing on a focused small spot, where the HRC/HB would have a test result from a much bigger area.
