Alloy Steel 4130
Alloy steel 4130 is a low-alloy steel that contains chromium and molybdenum. It has excellent strength, toughness, and fatigue resistance, making it ideal for use in applications that require high performance under stress. Additionally, it has good weldability and can be heat treated to achieve a wide range of mechanical properties. It is often referred to as "chrome-moly" steel.
The normal use cases for alloy steel 4130 include the manufacturing of aircraft components, bicycle frames, and automotive parts. It is commonly used in the production of fuselage frames, engine mounts, and landing gear components. Its strength, toughness, and weldability make it a popular choice for lightweight structures that require high performance and reliability.
