Metal material composition test

Metal material composition test

The scope of metal material testing involves mechanical perance testing, chemical composition analysis, metallographic analysis, precision dimensional measurement, non-destructive testing, corrosion resistance testing environmental simulation testing of ferrous metals, non-ferrous metals, mechanical equipment parts. The five major elements usually refer to the manganese, phosphorus, silicon, carbon, sulfur elements present in steel. They are the most important basic elements in steel. They distinguish the grades quality of ordinary steel. Their content directly affects the mechanical properties of steel.
