EN2A alloy steel

Introduction

We manufacture forging ingots, billets, and blooms in alloy steel specifically for EN2A, tailored for general engineering and low-stress applications. EN2A is a low carbon mild steel known for its excellent machinability, good formability, and adequate strength for light duty applications. Due to its low carbon content, EN2A offers good toughness and is ideal for components that do not require high hardness or heavy load-bearing capacity. It is widely used in general engineering, fabrication, and automotive parts where easy machining and cost effectiveness are key requirements.

Chemical composition

Element Content (%) Function / effect
Carbon (c) 0.12 max Provides basic strength and excellent machinability
Manganese (mn) 0.50 max Improves toughness and slight hardenability
Sulfur (s) Max 0.05 Enhances machinability; controlled to prevent brittleness
Phosphorus (p) Max 0.05 Improves machinability; excess may reduce toughness
Silicon (si) Low / trace Acts as deoxidizer and slightly increases strength

Mechanical properties

(typical values, may vary based on heat treatment and manufacturing conditions)

  • Tensile strength: approx. 370 – 480 MPa
  • Yield strength: approx. 220 – 280 MPa
  • Hardness: approx. 120 – 170 hb
  • Impact toughness: good
  • Ductility: excellent

Heat treatment

  • annealing: improves machinability and softness
  • normalizing: refines grain structure and enhances mechanical properties
  • EN2A is generally used in as-rolled or normalized condition and is not suitable for quench hardening due to low carbon content
