AISI 4130 Alloy Steel (Chromoly Steel) – Complete Technical Guide
What is AISI 4130 Alloy Steel?
AISI 4130 alloy steel is a high-strength, low-alloy steel that contains chromium and molybdenum as its primary strengthening agents. Often referred to by its common name, 4130 chromoly or Cr-Mo steel, this grade is celebrated in engineering circles for its exceptional combination of strength, toughness, fatigue resistance, and weldability. Its versatility makes it a cornerstone material in some of the world's most demanding industries.
The key advantages of 4130 alloy steel stem from its carefully balanced chemistry, which allows it to respond favorably to a wide range of heat treatments. This adaptability produces a material with a high strength-to-weight ratio, making it an ideal choice for applications where performance cannot be compromised. You will find this grade extensively used in the form of 4130 round bar for gears and shafts, AISI 4130 steel tube for aerospace and motorsport frames, and seamless pipes for high-pressure systems in the oil and gas sector.
