Remember to note that steel equivalent grades may have slight variations in chemistry between specifications. These are simply the closed grades commonly available in difference national / international specifications.
Basically you have to have the JIS book and the ASTM AISI SAE books also. AFter a few time going through the process you will begin remembering how to start. IE: SAE specs J403 is carbon steel, J404 is alloy steel, J405 is stainless. Or SPHC Means Steel Plate Hot-Rolled Commercial quality.
