Possible delivery conditions are annealed (subcritical annealing), normalized for ASTM A 829 - SAE 4140 and normalized + tempered for ASTM A 829 - SAE 4142. The delivery condition is to be agreed. a) control rolling (normalizing rolling) may replace furnace normalizing The plates are not delivered in the as rolled (AR) condition.
scope:(a) This specification covers untreated and heat treated carbon steel forgings for general industrial use.(b) The classes of forgings are as follows, the choice depending on design and stress or service to be imposed:Class A untreated, soft steel forgings.. Classes C, C1 and E, annealed, normalized, or normalized and tempered, mild steel forgings.
