Why choose 4140 material steel for delivery in annealed state?

ASTM 4140 material is a commonly used alloy steel with multifunctionality. Its excellent performance is mainly obtained through multiple heat treatment processes. Especially after annealing process, the performance of 4140 material steel is significantly enhanced, which is conducive to being applied to various fields, and is more conducive to steel stockists, wholesalers or distributors to store 4140 steel to promote business. Moreover, through Songshun’s experience in providing 4140 materials for many years, it is concluded that 90% of customers choose to purchase 4140 annealed steel. So, why choose 4140 material steel to be delivered in annealed state? Let’s take a closer look.

What Improvements Does the Annealing State Bring to the Internal Structure of 4140 Steel?

After annealing the 4140 material, the internal structure changes, which can effectively eliminate the internal stress in the steel and refine the grain structure of the steel, improve the defects inside the material, and make its internal structure more uniform and stable. This is conducive to preparing the organization and performance for the subsequent process, which is especially important for mechanical parts that require high precision and high reliability.

If annealing is not performed, the steel may be easily deformed or cracked during subsequent processing and use, affecting its processing quality and service life.

Outstanding Advantages: Multifunctionality and Excellent Performance

After perfect and appropriate annealing treatment, 4140 material steel has obtained more and better performance. Mainly manifested in the following points:

1. Improved toughness and plasticity, making it less prone to deformation and fracture, and better able to withstand external shocks, vibrations and loads, creating favorable conditions for subsequent processing and use.

2. Better processability and formability make 4140 easier to process, and can better meet the needs of various processing techniques, including cutting, welding, cutting, polishing, grinding, drilling, etc. And it can maintain high stability and consistency, ensuring processing efficiency and material size and quality.

3.Improved durability. In the annealed state, the 4140 material steel structure is more uniform and stable, which is conducive to extending its service life and making it more durable.

Optimal Hardness and Performance: Beneficial for Applications in Multiple Fields

After annealing, 4140 alloy steel reduces its excessive hardness, making its hardness and performance reach the best level, making 4140 material steel more conducive to being used in automobiles, machinery manufacturing, aerospace, oil and gas, etc., making it very suitable for machining, machine parts manufacturing, high-strength forging manufacturing, gear manufacturing, machine tool and tool manufacturing, etc. 4140 annealed steel performs well in many industries and has become one of their preferred materials.
