AISI 4140 Alloy Steel (UNS G41400) | Supplier & Stockist in UAE 

 

AISI 4140 is a chromium-molybdenum alloy steel known for its exceptional toughness, abrasion resistance, and high fatigue strength. As a low-alloy steel, it offers a superior strength-to-weight ratio, making it a cornerstone material for demanding industrial applications. Its versatility is further enhanced through various heat treatments, which allow you to precisely tailor its mechanical properties to meet specific operational requirements.

For engineers, fabricators, and procurement managers in sectors like oil & gas, automotive, and manufacturing, AISI 4140 provides a reliable solution for components subjected to heavy loads, high wear, and significant stress. Understanding its composition, properties, and treatment processes is critical to leveraging its full potential. This guide provides a detailed overview to support your material selection and procurement decisions.

 

Key Features and Properties

 

AISI 4140 Alloy Steel combines strength, hardness, and machinability, making it suitable for high-stress mechanical applications.
Here’s what makes it stand out:

  • High tensile and yield strength for structural integrity
  • Excellent wear and impact resistance under dynamic loads
  • Good fatigue strength for long-term performance
  • Uniform hardness and toughness after heat treatment
  • Machinable and weldable with appropriate precautions

4140’s chromium content enhances corrosion resistance, while molybdenum improves hardenability and toughness — making it a preferred choice in demanding environments.

 

Advantages of Using AISI 4140 Alloy Steel

 

Choosing AISI 4140 for your components provides several distinct operational advantages:

  • High Wear Resistance: Its ability to be hardened to a high degree makes it exceptionally resistant to abrasion and wear.
  • Excellent Toughness: It can withstand heavy shock and impact loads without fracturing, especially after proper tempering.
  • Durability and Fatigue Strength: The material resists cyclical loading and stress, ensuring a long service life for critical components.
  • Versatility: Through heat treatment, its properties can be tailored to an extensive range of applications, from tough and ductile to extremely hard and strong.
  • Cost-Effectiveness: It offers a high-performance alternative to more expensive specialty steels without compromising on strength and reliability.
