When strength needs form and complexity demands precision, alloy steel castings deliver. They are engineered to meet the structural, mechanical, and geometric demands of industries where failure is not an option. At Behari Lal Engineering, we specialize in delivering high-quality alloy steel castings that meet the demanding requirements of various sectors across India.

What Are Alloy Steel Castings?

Alloy steel castings are components shaped by pouring molten alloyed steel into moulds to create near-net or net-shaped parts. Unlike forging or rolling, casting allows highly intricate geometries and internal cavities to be manufactured with minimal post-processing.

These castings offer a tailored combination of:

• High tensile strength
• Good corrosion and heat resistance
• Superior wear performance
• Design flexibility

Why Use Alloy Steel for Castings?

Alloy steels combine iron with elements like chromium, molybdenum, nickel, vanadium, and manganese to enhance properties such as toughness, strength, and corrosion resistance. The casting process further allows these properties to be tailored to specific service environments.

Advantages of Alloy Steel Castings

Property	Benefit in Application
High Strength-to-Weight Ratio	Enables lightweight yet durable components
Excellent Toughness	Withstands shock loads and mechanical fatigue
Heat & Corrosion Resistance	Ideal for high-temp and aggressive chemical environments
Dimensional Accuracy	Precise control over complex shapes and internal features
Material Versatility	Grades can be customized for wear resistance, hardness, or ductility

Common Grades & Industrial Applications

Alloy Steel Grade	Typical Applications
ASTM A217 (WC6, WC9)	High-temperature valves, pump casings, pressure components
ASTM A487 Gr. 4C	Fracture-resistant parts in oil & gas and power sectors
ASTM A743 CA6NM	Corrosion-resistant pump impellers and housings
EN 10213 G17CrMo5-5	Petrochemical and thermal power systems
IS 1030 (C45/50)	General engineering: levers, brackets, covers

Casting Methods for Alloy Steels

At Behari Lal Ispat, we utilize multiple casting technologies based on part size, complexity, and application:

• Sand Casting
  Best for large, heavy-duty parts like pump bodies and gear housings.
• Investment Casting (Lost Wax)
  Ideal for high-precision components requiring intricate geometry, like turbine blades or impellers.
• Centrifugal Casting
  Used for cylindrical parts with uniform density—tubes, sleeves, and liners.

Market Insight: India’s Rise in Alloy Steel Castings
