Hardness testing to ISO 6508-1
Stainless Steel A2-70 Eye Bolts, conforming to the DIN 580 standard, are specialized fasteners designed for a variety of applications, particularly in lifting and rigging scenarios. These eye bolts are manufactured from AISI 304 stainless steel with a specific material grade designation, offering certain mechanical properties and corrosion resistance. Here are some key characteristics and considerations for these eye bolts:
Material and Grade: Stainless Steel A2-70 Eye Bolts are typically crafted from AISI 304 stainless steel. The "A2-70" designation signifies the material grade and its mechanical properties. In this case, "A2" denotes AISI 304 stainless steel, which contains 18% chromium and 8% nickel. The "70" represents the minimum tensile strength, approximately 700 MPa, making these eye bolts suitable for various applications.
Design and Function: These eye bolts feature a threaded shank with a closed-looped eyelet at one end. The threaded portion is used to securely fasten the eye bolt to a load-bearing structure or component, while the eyelet provides a secure anchor point for attaching lifting equipment, cables, or hooks. This design ensures a stable and reliable connection, making them suitable for lifting and suspending loads.
Applications: Stainless Steel A2-70 Eye Bolts according to DIN 580 are commonly employed in lifting, rigging, and suspension applications across various industries, including construction, maritime, and manufacturing. They are essential components for hoisting machinery, equipment, and heavy loads, especially when corrosion resistance and reliable load-bearing capabilities are required.

Corrosion Resistance: AISI 304 stainless steel provides good corrosion resistance, making A2-70 Eye Bolts suitable for use in a wide range of environments. However, they may not be as corrosion-resistant as higher-grade stainless steels like AISI 316 (A4-70) in highly corrosive conditions. Regular maintenance and inspection are essential to ensure their longevity in challenging environments.
Safety Considerations: When using A2-70 Eye Bolts for lifting, it is critical to adhere to proper installation procedures and adhere to load rating guidelines. Ensure that the eye bolt is securely fastened to a load-bearing structure and can handle the anticipated load capacity. Routine inspections are crucial to confirm that the eye bolts are free from defects and remain in good working condition.
