Product Description
SAE 4617/4615 EN34 Hot Forged Steel Round Bar
1: BS EN34 Steel Introduction
EN34 is a 2% nickel, molybdenum case hardening steel grade. Combining good core strength, toughness and fatigue resistance this grade can be case hardened up to 60HRc. EN34 is suitable for applications requiring wear resistance and shock resistance. It offers good core strength and impact properties with little temper brittleness.

7: BS EN34 Steel Application
BS EN34 is suitable for shafts, gears, transmission parts, camshafts and cams, cam shafts connecting rods crankshafts gears.
8: BS EN34 Carburising / Case Hardening
Carburising and case hardening will give a hard wear resisting surface and a tough core strength to the steel. EN34 is suited for carburising and case hardening. Surfaces must be free from dirt and grease, and of low sulphur content. Case hardening can be carried out in salt baths with selected content depending on the type of salt and the depth of penetration required. Other considerations during the heat treatment process include the type of furnace, quenching medium and work piece transfer facilities. Time, temperatures and salt selection will be advised by your heat treatment provider.
9: BS EN34 Steel Heat Treatment
Heat treatment temperatures, including rate of heating, cooling and soaking times will vary due to factors such as the shape and size of each EN34 steel component. Other considerations during the heat treatment process include the type of furnace, quenching medium and the work piece transfer facilities. Please consult your heat treatment provider for full guidance on heat treatment of EN34 case hardening steel.
