Stainless Steel 304, also known as 1.4301, is a commonly used austenitic stainless steel alloy. It is known for its excellent corrosion resistance, versatility, and wide range of applications. The "hex bolt" designation refers to the specific shape and use of the stainless steel material as a bolt with a hexagonal head.


Here are some key features, applications, and information regarding the corrosion resistance of Stainless Steel 304 Hex Bolts (1.4301):

Features:

  • Corrosion Resistance: One of the primary features of Stainless Steel 304 is its exceptional corrosion resistance. It is resistant to a wide range of corrosive environments, including most chemicals, acids, and atmospheric conditions. This resistance is due to the presence of chromium in the alloy, which forms a passive oxide layer on the surface that prevents further corrosion.
  • Strength and Durability: Stainless Steel 304 offers good strength and durability, making it suitable for various applications, including those requiring load-bearing capabilities.
  • Heat Resistance: It has good heat resistance, which allows it to perform well in high-temperature applications, such as industrial ovens and furnaces.
  • Formability: Stainless Steel 304 is easily formable and can be welded, bent, and fabricated into various shapes, making it suitable for a wide range of manufacturing processes.

Applications: Stainless Steel 304 Hex Bolts (1.4301) find applications in numerous industries, including:


  • Construction: Used for fastening structural components and fixtures due to its strength and durability.
  • Automotive: Found in automotive components, such as engine parts and exhaust systems.
  • Food Processing: Stainless Steel 304 is safe for use in food processing equipment due to its corrosion resistance and non-reactive nature.
  • Medical and Pharmaceutical: It is used in medical equipment and devices where hygiene and corrosion resistance are essential.
  • Chemical Processing: Stainless Steel 304 is suitable for handling a wide range of chemicals and corrosive substances, making it common in the chemical industry.
  • Marine Applications: Due to its resistance to saltwater and atmospheric corrosion, it's used in marine environments for boat components and fixtures.
  • Aerospace: Used in aircraft components where corrosion resistance and high strength are required.


Corrosion Resistance: Stainless Steel 304 offers excellent corrosion resistance in a variety of environments, including exposure to moisture, chemicals, and salt. Its corrosion resistance is primarily attributed to the alloy's composition, which typically contains approximately 18-20% chromium and 8-10.5% nickel. The chromium in the steel forms a passive oxide layer on the surface when exposed to oxygen, which acts as a barrier against further corrosion.
