A4-80 stainless steel refers to a high-grade, corrosion-resistant stainless steel with a minimum tensile strength of around 800 MPa. It's commonly used in applications where high corrosion resistance and mechanical strength are required, such as in marine environments or in chemical processing industries

Grade A4-80 Stainless Steel Fasteners are hardware components made from a specific grade of stainless steel known as A4-80. This grade is also referred to as AISI 316 or 18/8/3 stainless steel and is an austenitic stainless steel with even higher corrosion resistance compared to the A4-70 grade. The chemical composition of Stainless Steel Grade A4-80 typically includes 16-18% chromium, 10-14% nickel, 2-3% molybdenum, 1% max manganese, 1% max silicon, 0.07% max carbon, and small amounts of other elements like sulfur, phosphorus, and nitrogen.


One of the key features of Stainless Steel Grade A4-80 Fasteners is their outstanding corrosion resistance. The higher molybdenum content in the alloy further enhances its resistance to corrosive environments, particularly in chloride-rich environments. This makes them highly suitable for applications in marine and coastal environments, as well as in chemical processing plants where exposure to corrosive chemicals is significant.


Stainless Steel Grade A4-80 Fasteners also offer excellent mechanical properties, including higher tensile strength compared to the A4-70 grade. The A4-80 designation indicates that these fasteners have a minimum tensile strength of 800 MPa, making them suitable for applications that require higher load-bearing capabilities and stronger connections.

Due to their superior corrosion resistance and higher tensile strength, Stainless Steel Grade A4-80 Fasteners find extensive use in demanding applications. They are commonly used in the marine and offshore industries, including shipbuilding, offshore platforms, and seawater-cooled systems. The A4-80 fasteners are well-suited for critical applications where resistance to chloride-induced corrosion and high mechanical strength are essential for long-term performance.


Moreover, Stainless Steel Grade A4-80 Fasteners are employed in chemical processing plants, desalination facilities, and other industrial applications that require resistance to corrosive chemicals and high-temperature stability. Their combination of excellent corrosion resistance, mechanical strength, and versatility makes them an ideal choice for fastening solutions in various challenging environments.
