EN45

EN45 is a silico-manganese spring steel widely used for the manufacture of leaf springs and knives. Whilst it has been manufactured as both strip and bar in the past, the development of more sophisticated strip steels mean it is no longer generally available in strip form,

EN45 is most commonly supplied as black as rolled  flat bar which is formed with or without heating and quenched and tempered when the desired shape has been achieved.

Related steel grades include BS970 250A53, 56Si7, 55Si7  and SAE 9260
