Composition of EN353 Steel

The chemical composition of EN353 is carefully balanced to deliver its unique properties:

• Carbon (C): 0.14–0.19%

• Manganese (Mn): 0.60–0.90%

• Silicon (Si): 0.10–0.35%

• Chromium (Cr): 1.00–1.30%

• Nickel (Ni): 1.00–1.50%

• Molybdenum (Mo): 0.10–0.20%

  This combination of elements ensures excellent hardenability, toughness, and resistance to fatigue.

Material Properties of EN353 Round Bar

EN353 round bars are prized for their exceptional mechanical properties, which include:

• High Surface Hardness: Achieved through case hardening, EN353 can reach surface hardness levels of 55–62 HRC.

• Tough Core: The core remains ductile and impact-resistant, making it suitable for heavy-duty applications.

• Wear Resistance: Ideal for components exposed to friction and abrasion.

• Machinability: EN353 is relatively easy to machine in its annealed state, allowing for precise fabrication.

• Heat Treatability: Responds well to heat treatment processes like carburizing, quenching, and tempering.

Applications of EN353 Round Bar

The versatility of EN353 makes it a preferred material for a wide range of applications, including:

• Gears and Pinions: Its high surface hardness and toughness make it ideal for gear manufacturing.

• Shafts and Axles: EN353’s durability ensures long-lasting performance under heavy loads.

• Bearings and Bushings: Its wear resistance is perfect for components subjected to friction.
