 S32760 Super Duplex Stainless Steel Round Bar

S32760 round bar, also known as F55 (UNS S32760) or 1.4501, is a ‌super duplex stainless steel‌ combining austenitic and ferritic microstructures‌12. This dual-phase alloy contains high levels of chromium (25%), nickel (7%), molybdenum (3.5%), nitrogen (0.3%), and tungsten (0.7%), delivering exceptional ‌corrosion resistance‌, ‌high strength‌, and ‌thermal stability‌‌14. Its unique composition makes it ideal for harsh industrial applications.

Key Performance Advantages

 

Superior Corrosion Resistance‌:

  • Resists pitting, crevice corrosion, and stress corrosion cracking (SCC) in chloride-rich environments (e.g., seawater, acidic/alkaline media)‌34.
  • Maintains integrity in temperatures up to 300°C, with excellent oxidation resistance‌24.

Outstanding Mechanical Properties‌:

  • Tensile strength: 750–895 MPa; Yield strength: ≥550 MPa; Elongation: ≥25%‌23.
  • Higher strength than standard duplex steels, reducing material thickness and weight in structural designs‌14

Weldability and Fabrication‌:

  • Compatible with TIG, MIG, and laser welding techniques. Requires controlled heat input to avoid phase imbalance‌34.
  • Suitable for machining, forging, and precision cutting (e.g., waterjet or laser)‌45.

Production Methods

S32760 round bars are manufactured through:

  1. Raw Material Selection‌: High-purity chromium, nickel, and molybdenum alloys‌12.
  2. Melting and Casting‌: Vacuum induction melting (VIM) ensures uniform composition; continuous casting forms billets‌13.
  3. Thermal Processing‌:
  • Solution annealing at 950–1100°C followed by rapid cooling to optimize phase balance‌25.
    1. Finishing‌: Hot/cold rolling, grinding, or polishing to achieve precise dimensions and surface quality‌15.

Applications in Critical Industries

S32760 round bars are widely used in:

  • Oil & Gas‌: Subsea pipelines, valves, and pumps for sour service environments‌34.
  • Marine Engineering‌: Desalination plants, shipbuilding components, and offshore platforms‌35.
  • Chemical Processing‌: Reactors, heat exchangers, and acid storage tanks‌24.
  • Power Generation‌: Boiler systems and flue gas scrubbers in thermal plants‌45.

In demanding industrial environments, the integrity of a structure often depends on its smallest components: the fasteners. 2205 Duplex Stainless Steel Bolts have emerged as the “workhorse” of the industry, offering a superior alternative to standard grades like 316. Understanding why we need these high-performance Alloy 2205 Bolting solutions requires looking at their unique chemistry, history, and the critical roles they play across global industries.

Manufacturing 904L bolts is significantly more difficult than manufacturing standard 304 or 316 grades. While 904L is highly ductile, its high nickel (25%) and molybdenum (4.5%) content make it extremely tough and prone to rapid work-hardening,  When welding 904L studs or components, use matching filler metals (e.g., 20 25 CuL) and avoid pre-heating to prevent hot cracking. Use Tri-Roll Thread Comparators and calibrated gauges to ensure precision, as 904L is prone to galling (seizing) during assembly if threads are not perfect.

In the demanding industrial landscape of 2026, the integrity of a project depends entirely on the fasteners used. Whether securing a jet engine component operating at extreme temperatures or erecting an offshore wind turbine, the choice of material and specification is critical for safety, longevity, and performance.
As a premier manufacturer, we specialize in high-precision fastening solutions tailored for extreme environments, featuring advanced materials like Incoloy A286.
