Punit Fasteners, a well-respected manufacturer and supplier located in Delhi, India, specializes in high-quality Duplex Steel Bolts S32205, crafted for outstanding performance in tough industrial settings. These bolts are made with a carefully balanced mix of austenite and ferrite, which gives them remarkable strength, durability, and resistance to corrosion. They’re particularly known for their ability to handle chloride-induced stress corrosion cracking, pitting, and crevice corrosion, making Duplex Steel S32205 Bolts perfect for critical applications in marine, chemical, oil and gas, and power generation sectors. Punit Fasteners guarantees that each bolt adheres to international quality standards, providing reliable fastening solutions that stand the test of time and high-stress conditions.
Duplex Steel Bolts S32205 consist of about 22% chromium, 5-6% nickel, 3% molybdenum, nitrogen, and the rest being iron, which gives them double the tensile and yield strength compared to regular austenitic stainless steels. This unique composition results in exceptional mechanical properties, including impressive toughness and fatigue resistance, even in low temperatures. These bolts excel in resisting localized corrosion and stress corrosion cracking while still maintaining high ductility. Their robust strength and stability make them perfect for heavy-duty and high-pressure environments, ensuring they perform reliably in both industrial and marine applications.
