Ⅰ.Material selection:

HULK Metal selected specific materials to ensure optimal performance and longevity . The more commonly used materials include 20Mn2, Q345D, CM490, and stainless steel. They have unique advantages and can provide a variety of choices for different environments.

1. 20Mn2: 

Known for its high strength and excellent weldability, 

20Mn2 

is a popular choice for spherical head anchors  that require excellent mechanical properties. Its ability to withstand heavy loads and shocks makes it suitable for demanding applications.

2. Q345D: 

This low-alloy steel provides a balance of strength and ductility, making it ideal to dynamic loads or harsh environmental conditions. 

Q345D 

has good weldability and corrosion resistance, which can increase the service life of the anchor bolt.

3. CM490: 

CM490 steel has excellent tensile strength and toughness, making it suitable for spherical head anchors  used in heavy-duty applications. Its superior performance in extreme conditions makes it a reliable choice for critical applications where safety is critical.

4. Stainless Steel: 

Known for its corrosion resistance and durability, stainless steel is an excellent choice for spherical head anchors  deployed in corrosive environments or exposed to moisture. Its anti-rust and anti-fouling properties ensure long-term reliability and aesthetics.

Ⅱ.Production process:

Die forging is a widely used manufacturing technique for spherical head anchors  because of its ability to produce parts with excellent mechanical properties and dimensional accuracy. The process involves:

1. Preparation: 

The selected material is heated to a precise temperature to improve its formability and reduce the risk of cracking during the forging process.

2. Forming: 

Put the heated material into the mold cavity, where it is subjected to compression force to shape it into the desired spherical head anchor structure.

3. Trimming: 

Excess material is trimmed away to achieve the final shape and size of the anchor, ensuring precise tolerances and surface finish.

4. Finishing: 

The forged anchor bolt undergoes a surface treatment process to enhance its corrosion resistance and aesthetics, further improving its durability and functionality.

Ⅲ.Surface treatment:

Surface treatment plays a vital role in protecting the anchors  from corrosion and extending their service life. Common surface treatment methods include:

1. Original Color: 

This involves leaving the surface of the anchor in its natural state after forging, providing basic protection against corrosion. It is suitable for indoor applications or environments with minimal exposure to moisture and corrosive elements.

2. Electro-galvanizing: 

In this process, a layer of zinc is electrodeposited onto the surface of the anchor bolt, forming a protective barrier against corrosion. Electro-galvanized spherical head anchors  are suitable for outdoor applications requiring moderate corrosion resistance.

3. Hot-dip galvanizing: 

they are immersed in molten zinc during the hot-dip galvanizing process, forming a thick, durable coating that provides superior corrosion protection. They are ideally suited for use in marine environments, industrial facilities and other harsh conditions requiring superior corrosion resistance.
