A2 -70 Fasteners

A2-70 fasteners are a specific type of stainless steel fastening components known for their excellent corrosion resistance and mechanical properties. The "A2" designation refers to the stainless steel grade, which is commonly known as 304 stainless steel in the ASTM standard. This grade contains a combination of chromium and nickel, providing good corrosion resistance in most atmospheric and mild chemical environments. The "70" indicates the minimum tensile strength of the fastener, which is approximately 700 MPa.

These fasteners are widely used in various industries and applications where corrosion resistance and moderate strength are required. Common applications include construction, automotive, marine, and food processing equipment. A2-70 fasteners are suitable for use in indoor and outdoor environments, but they may not be as resistant to corrosion in highly corrosive or marine environments as some other stainless steel grades.

A2-70 fasteners come in a range of types, including bolts, nuts, screws, washers, and threaded rods, and they are available in various sizes and configurations to suit different requirements. Their versatility, combined with their corrosion resistance and moderate strength, makes them popular choices for many engineering and construction projects. However, it's essential to consider the specific environmental conditions and application requirements when selecting fasteners to ensure optimal performance and longevity.
