Advantages of Duplex Steel S31803 Fasteners

  1. Corrosion Resistance: Duplex steel S31803 fasteners exhibit excellent corrosion resistance, especially in aggressive environments such as marine and chemical processes. They resist general wear and tear, including pitting and crack corrosion.

  2. Wide range of applications: Due to their superior mechanical properties and corrosion resistance, S31803 fasteners are suitable for a wide range of applications in oil and gas, chemical processing, marine engineering, pulp and paper, etc. They are used in a variety of structural, mechanical, and important bonding functions.

  3. Cost Effectiveness: Although the initial cost of a pair of steel S31803 fasteners may be high compared to some other materials, their high corrosion resistance, strength, and generally low cost over the life span require no maintenance, replacement, or decommissioning, resulting in overall cost savings.

  4. Duplex microstructure: The duplex microstructure of S31803 steel balances austenitic and ferritic phases. Compared to conventional austenitic or ferritic stainless steels, this structure contributes to strength and flexibility in terms of compression, corrosion and cracking resistance.

  5. Strength: These fasteners are very strong, allowing them to withstand heavy loads and high pressures. The energy they store is also stored at high temperatures, making them suitable for use in a variety of industrial applications.
