carbon steel?
 
Hello encik_lai,

The only element of interest there is C with it's 0.47% suggesting a mild carbon steel unalloyed. Like http://www.matbase.com/material-cat...erial-properties-of-high-grade-steel-c45.html
So close to a C45 or 1.0503.
The other impurities are the usual result of melting down 2 oil-tankers 500 cars and nuclear reactor parts and low purification thereafter as this steel is not with very expensive properties.
 
Ah forgot to mention, all said above is true for mass %.
 
Fe 98.4, Mn 0.67, C 0.472, Si 0.216, is a medium carbon steel, not a mild steel.The Mn gives it some wear resistance.

Medium carbon steel: approximately 0.29% to 0.54% carbon content with 0.60 to 1.65% manganese content (e.g. AISI 1040 steel). Balances ductility and strength and has good wear resistance;
