The S32760 Hex Bolt is a high-performance fastening solution crafted from super duplex stainless steel (UNS S32760, also known as F55 or W.Nr 1.4501)—a material renowned for its exceptional strength and resistance to corrosion. Compliant with global standards including DIN933, DIN931, ISO4017, ISO4014, and ASME B18.2.1, this hex bolt is designed for demanding industrial environments where reliability and durability are non-negotiable. We have established ourselves as a leading supplier of S32760 fasteners, with a proven track record: our bolts have been used in cooling tower systems of Oman Power Plant (2010, 2016, 2024) and Mexico Power Plant (2024), among other high-profile projects. With stock quantities up to 100,000 pieces (e.g., M12X100) and custom capabilities, we cater to both small-scale repairs and large-scale industrial projects.

Superior Material Performance: S32760 super duplex steel delivers a tensile strength of 820 N/mm² and yield strength of 550 N/mm² (at room temperature), combined with 25% elongation—outperforming standard stainless steels in high-load and high-vibration applications. It also resists pitting, crevice corrosion, and chloride-induced stress cracking, making it ideal for harsh environments.
Global Standard Compliance: Manufactured to DIN933 (full thread), DIN931 (partial thread), ISO4017, ISO4014, and ASME B18.2.1 standards, ensuring compatibility with international fastener systems. This eliminates fitment issues when integrating with components from different regions.
Wide Size Range: Covers thread sizes from M5 to M100 (or 1/4–4” for imperial needs), with lengths tailored to your requirements. Common sizes (e.g., M12X100) are in stock for same-week delivery, while larger or non-standard lengths are produced quickly.
Certified Quality & Traceability: Every batch comes with EN10204-3.1B certification, providing full traceability of material origin, chemical composition (Ni: 6.0–8.0%, Cr:24–26%, Mo:3.0–4.0%), and mechanical properties. This meets the strict standards of power, oil, and nuclear industries.
Customizable Markings & Packaging: Supports custom markings (e.g., your brand name + grade “S32760”) for easy identification. Packaging options include bulk boxes, cartons on pallets, or customer-specific packaging (e.g., anti-rust bags for sea shipping) to protect bolts during transit.
The S32760 Hex Bolt’s unique combination of strength and corrosion resistance makes it suitable for critical applications:
Power Generation: Dominantly used in cooling tower systems of thermal and nuclear power plants (e.g., Oman, Mexico projects). It secures heat exchangers, fan components, and pipe brackets, withstanding high humidity, chemical residues, and temperature fluctuations.
Oil & Gas Industry: Applied in offshore platforms, onshore refineries, and pipeline systems. Its resistance to saltwater (offshore) and hydrocarbon vapors (refineries) ensures long-term performance in flange connections, valve mounts, and structural supports.
Marine Engineering: Used in shipbuilding (hull fittings, deck equipment) and coastal infrastructure (port cranes, seawater desalination plants). S32760’s resistance to marine corrosion eliminates frequent replacements, reducing maintenance costs.
Chemical Processing: Integrated into reactors, storage tanks, and mixing equipment handling acids (e.g., sulfuric, phosphoric) or chlorides. The material’s stability prevents contamination and ensures process safety.
A1: S32760 has direct equivalents: UNS S32760, DIN W.Nr 1.4501, and ASTM F55. These grades share identical chemical compositions and mechanical properties, so bolts marked with any of these designations are interchangeable.
A2: Yes, we provide free samples (up to 5 pieces) for quality testing. Samples are typically shipped within 3–5 business days and include a copy of the EN10204-3.1B certificate for your verification.
A3: For orders exceeding USD50,000, we accept Letter of Credit (L/C) in addition to our standard payment methods (T/T, Western Union). L/C terms can be customized to align with your company’s procurement policies, ensuring mutual security.
A4: No special maintenance is needed. The super duplex steel’s corrosion resistance means it can be used in outdoor or harsh environments without regular coating or treatment. For extreme conditions (e.g., constant salt spray), we recommend occasional cleaning with fresh water to remove debris, but this is optional.
A5: Yes. We offer non-standard thread lengths (e.g., longer partial threads for deep connections) and custom coatings (e.g., PTFE for low-friction applications) via OEM services. Simply provide your drawing or specifications, and we’ll quote a timeline (typically 2–3 weeks for non-standard production).
