The purchaser should, therefore, be aware that testing of one plate, bar, or shape does not provide assurance all plates, bars, or shapes of the same heat as processed will be identical in toughness with the product tested. The impact properties of steel can vary within the same heat and piece, be it as rolled, control rolled, or heat treated.
