En15AM alloy steel

Introduction

We manufacture forging ingots, billets, and blooms in alloy steel specifically for En15AM, tailored for high-performance applications.

En15AM is a medium carbon, high manganese alloy steel designed for general engineering applications where good strength, toughness, and machinability are required. The elevated manganese content improves hardenability and impact strength, making this grade suitable for components subjected to moderate loads and stresses.

En15AM is commonly supplied in normalized or as-rolled condition and can be heat treated to enhance Mechanical properties  for structural and automotive applications. This versatility makes it ideal for forged and machined parts requiring reliable performance and durability.

Chemical composition

Element	Content (%)	Function / effect
Carbon (c)	0.30 – 0.40	Provides balanced strength and hardness
Manganese (mn)	1.30 – 1.70	Improves hardenability, toughness, and wear resistance
Sulphur (s)	0.020 max	Controlled for better machinability
Phosphorus (p)	0.060 max	Impurity; limited to maintain toughness
Silicon (si)	0.25 max	Increases strength and elasticity
Chromium (cr)	Nil	Not present
Nickel (ni)	Nil	Not present
Molybdenum (mo)	Nil	Not present

Mechanical properties (typical values after normalizing / heat treatment )

• tensile strength: moderate to high
• hardness: moderate (application dependent)
• toughness: good
• wear resistance: moderate
• machinability: good

Heat treatment

• normalizing: improves grain structure and mechanical properties
• hardening: heating followed by quenching to increase strength
• tempering: performed to reduce brittleness and improve toughness

Proper heat treatment  ensures optimum performance and dimensional stability in service.
