Advantages of Duplex Steel S31803 Bolts

  • Corrosion Resistance: Duplex steel S31803 bolts exhibit excellent corrosion resistance, especially in harsh environments such as marine and chemical applications. They are resistant to chloride-induced stress, making them vulnerable to cracking and suitable for use in chloride-containing environments.

  • Easy to manufacture: Duplex steel S31803 bolts are extremely easy to machine, weld, and fabricate, allowing for efficient manufacturing and design flexibility. This simple manufacturing process contributes to their widespread use in various industries.

  • Cost-effectiveness: Despite its superior characteristics, duplex steel S31803 bolts can often provide cost savings compared to other corrosion-resistant alloys. This is due to their low nickel content and the materials available, making them a budget-friendly choice for many applications.

  • Hardness: Due to their balanced microstructure, duplex steel S31803 bolts offer superior hardness compared to other stainless steel grades. This rigidity resists shock and fatigue loads and reduces the risk of accidental failure.

  • Strength: These bolts have high strength derived from their dual microstructure of austenite and ferrite phases. This maintains their mechanical properties at high and low temperatures, ensuring reliability and durability under operating conditions.
