EN9 Carbon Steel
EN9 carbon steel is a medium carbon steel grade commonly supplied in the as-rolled condition. It can be flame or induction hardened to produce a high surface hardness with excellent wear resistance for a carbon steel grade. EN9 bar is available in full lengths or can be cut to your requirements. EN9 carbon round steel bar flame cut steel plates can be supplied cut to your required sizes and normalized. Flame cut plates can be supplied Lumsden ground or precision ground.

Flame Cut Profiles
Nifty Alloys LLC are suppliers of EN9 flame cut steel profiles. A hard edge can occur when flame cutting EN9 plates therefore this grade is commonly normalised after cutting. EN9 flame cut profiles can be supplied Lumsden ground or precision ground.
Ground Flat Stock
Precision ground flat stock / gauge plate can be produced using EN9 steel. Subject to size suitability and availability of raw material pieces can be produced in approximately 2 to 3 weeks. Standard and non-standard sizes are available.
Forging
Preheat the component carefully, then raise the temperature to 1100°C for forging. Do not forge below 850°C. After forging cool slowly, preferably in a furnace.
Annealing
Heat the steel slowly to 680-710°C, soak well. Cool slowly in the furnace.
Hardening
Heat slowly to 820-840°C and allow it to be heated through. Quench in oil, brine or water.
