Stainless Steel A2-70 Hex Bolts are a critical component in various industrial and construction applications, known for their exceptional strength and corrosion resistance. These bolts are made from A2 stainless steel, which contains approximately 18% chromium and 8% nickel, providing excellent resistance to rust and oxidation. The "70" in A2-70 denotes the bolt's tensile strength, indicating that it can withstand a load of up to 700 MPa. This makes a2 70 hex bolts suitable for use in environments where durability and reliability are paramount, such as marine, automotive, and construction industries.


Vision Alloys, a leading stainless steel a2 70 hex bolt manufacturer, ensures that each bolt meets stringent quality standards. The hex head design of these bolts allows for easy tightening and loosening with a standard wrench, making them versatile and easy to use in various applications. The precision engineering of a2 70 hex head bolts ensures a secure fit and excellent performance, even in demanding conditions. We utilize advanced manufacturing techniques and high-quality raw materials to produce bolts that meet and exceed industry expectations.



Features:

  • Material Composition: A2-70 stainless steel is primarily composed of iron (Fe), chromium (Cr), and nickel (Ni). It is often referred to as AISI 304 stainless steel in the United States. The "A2" designation signifies that it is part of the 300 series stainless steels, which are known for their corrosion resistance properties.
  • Tensile Strength: The "70" in A2-70 represents the minimum tensile strength in megapascals (MPa), which is approximately 700 MPa. This indicates that A2-70 stainless steel hex bolts have a moderate level of tensile strength suitable for many general-purpose applications.
  • Corrosion Resistance: A2-70 stainless steel offers good corrosion resistance in various environments, particularly in moderately corrosive settings. Its high chromium content (typically around 18%) forms a protective oxide layer on the surface, which helps prevent rust and corrosion.
  • Hex Head Design: Hex bolts are characterized by their hexagonal head shape, which allows for easy tightening and loosening with a wrench or socket tool. The hex head design provides a secure and stable grip during installation and removal.
