The austenitic phase contributes significantly to the bolts' strength, allowing them to withstand high levels of stress and pressure. In contrast, the ferritic phase enhances toughness, enabling the bolts to absorb impact without fracturing. This combination not only provides superior resistance to stress corrosion cracking but also ensures durability in extreme temperatures and corrosive conditions. As a result, Super Duplex Steel Hex Bolts are trusted for their reliability and longevity, helping to ensure the integrity of critical structures and equipment in challenging operational settings.
