Stainless Steel A4-80 Hex Bolt is a specific type of fastener known for its durability and corrosion resistance. Here are its features, corrosion resistance, machining, and applications:


Features:

  • Material: A4-80 refers to a specific grade of stainless steel, often known as 316 stainless steel. It contains around 16-18% chromium, 10-14% nickel, and 2-3% molybdenum, which gives it excellent corrosion resistance properties.
  • Strength: The "A4-80" designation indicates its mechanical properties, with an A4 grade being roughly equivalent to an A2 grade but with higher tensile strength. The "80" signifies the minimum tensile strength in megapascals (MPa).
  • Hex Bolt: A hex bolt features a hexagonal head, which can be easily tightened or loosened with a wrench or a socket.
  • Threaded: These bolts have threads along their shank, allowing them to securely fasten objects together.
  • Durable: Stainless steel A4-80 hex bolts are highly resistant to corrosion, making them suitable for use in various environments, including marine and chemical industries.

Corrosion Resistance: Stainless Steel A4-80 is renowned for its exceptional corrosion resistance, making it suitable for applications in harsh and corrosive environments. Its resistance to rust, staining, and pitting corrosion makes it ideal for marine, coastal, and chemical processing applications.


Machining: Machining stainless steel A4-80 can be more challenging than machining lower-grade steels due to its increased hardness and toughness. Specialized tools and techniques may be required. It's important to avoid work-hardening, which can lead to increased tool wear and difficulty in machining.
