AISI 4130 Alloy Steel | Properties, Applications & Supplier – Nifty Alloys LLC

What Is Alloy Steel 4130 (UNS G41300)?

AISI 4130 Alloy Steel is a general-purpose chromium-molybdenum low alloy steel that offers a better combination of strength, toughness, weldability, and fatigue strength. It is also known as Chromoly Steel, and AISI 4130 is broadly utilized in demanding engineering applications such as aerospace components, oil & gas equipment, automobile components, and defense systems.

Thanks to its superb mechanical properties and suitability for heat treatment, AISI 4130 is popular among industries requiring high performance levels under stress and aggressive conditions. We at Nifty Alloys LLC stock AISI 4130 Alloy Steel in bars, plates, tubes, pipes, and forgings as per requirements with guaranteed quality and international certifications.

Key Features and Benefits

Why industries choose AISI 4130:

• Weldability: 4130 can be welded using almost any commercial bonding method due to its relatively low carbon content without losing integrity or performance. 
• Machinability: This alloy can be successfully machined using standard methods, especially after being normalized and tempered. Although 4130 can be machined after being subjected to complete heat treatment, greater hardness can complicate the machining of this material. 
• Formability: 4130 has excellent ductility when annealed which allows tight bends and efficient col or hot forming, if necessary.
• Ductility and Strength: It also has superb flexibility after being annealed, meaning hot work is less of a necessity. Where hot work is necessary, 2000° through 1500° will be adequate.
• Heat Treatability: Heat treating 4130, like soaking in 1600° before quenching in oil, can harden the steel completely. Tempering after hardening, even at temperatures as low as 750° up to 1050°, can help restore ductility lost through hardening while retaining control of strength and resiliency.
• Versatility: 4130 is desirable for its excellent mechanical properties and is useful in structural applications, as well as automotive, aerospace, and racing applications.
   

These properties make 4130 steel an excellent choice where both strength and ductility are required.
