Copy AISI 4140 +QT as specified on your order. State whether the bar must be quenched and tempered at delivery; list machining or later heat treatment separately. Give diameter, cut length, piece count and destination. If hardness is specified, say where it must be checked and whether the result must be linked to the heat or lot. Confirm the heat-treatment condition and surface finish separately. The catalogue entry does not confirm availability or acceptance.
