Stainless Steel A4-80 Hex Nut is a hexagonal nut made from high-strength, corrosion-resistant AISI 316 stainless steel with a minimum tensile strength of 800 MPa. These nuts are suitable for applications where both high mechanical strength and excellent corrosion resistance are required, such as in marine, chemical, or harsh environmental conditions.
Features:
• Stainless Steel Grade A4-80 is a high-strength austenitic stainless steel that is known for its excellent corrosion resistance and mechanical properties.
• A4-80 refers to the specific grade and strength of the stainless steel, with "A4" indicating the stainless steel group and "80" denoting the minimum tensile strength in megapascals (MPa).
• Hex nuts are six-sided fasteners with internal threads designed to be used with bolts or threaded rods.
• A4-80 hex nuts are manufactured to meet specific strength and corrosion resistance requirements, making them suitable for demanding applications.
Corrosion Resistance:
• A4-80 stainless steel offers exceptional corrosion resistance, particularly in aggressive environments such as marine, chemical, and coastal settings.
• This grade contains high levels of chromium (around 16-18%) and nickel (approximately 10-13%), which form a protective passive oxide layer on the surface, preventing rust and corrosion.
• It is highly resistant to pitting and crevice corrosion, making it ideal for use in chloride-rich environments.
Machining:
• Stainless Steel A4-80 is known for its machinability, which means it can be easily cut, drilled, and tapped.
• However, it can work harden quickly during machining, so proper cutting tools and techniques are essential to maintain its desired properties.
• Lubrication and cooling during machining operations are recommended to enhance tool life and maintain surface finish.
