Steel Billets for Automotive Forgings

Automotive forging is a volume business. Billets are cut, heated and forged in presses, so section accuracy and consistent chemistry matter most.

Typical components

A widely used chrome-moly steel with good hardenability, toughness and fatigue strength in the quenched and tempered condition.

The American-designation counterpart of EN19 and 42CrMo4. Strong, tough and easy to heat treat.

A low carbon Ni-Cr-Mo steel that carburises to a hard surface over a tough core.

A manganese-chromium case hardening grade used for automotive and industrial gears.

A slightly lower carbon sibling of 20MnCr5, giving a tougher core after carburising.

Case hardening grades such as 8620 and 20MnCr5 are common for gears. State the heat treatment and grain size requirement in the order.

Check the billet size chart for sections and weight per metre, and use the weight calculator for any length.
