Duplex Steel UNS S32760 Round Bars

We at Sangeeta Metal manufacture and supply Duplex Steel UNS S32760 Round Bars for industries that prioritize corrosion resistance in chloride-heavy or high-pressure environments. This super duplex grade, also known as Zeron 100, combines high mechanical strength with corrosion resistance that standard austenitic stainless steel doesn't match. Our stock covers standard and custom diameters, cut and finished to project specification, with mill certification backing every batch. Buyers across oil and gas, marine engineering, and chemical processing rely on us for round bar that performs in the exact conditions their equipment operates in, without the guesswork that comes from unverified material.

What are Duplex Steel UNS S32760 Round Bars?

Duplex Steel UNS S32760 Round Bars fall under the super duplex stainless steel category, also designated WNR 1.4501 or F55. The alloy carries a balanced austenitic-ferritic microstructure, roughly split evenly between the two phases, which gives it mechanical properties that neither phase achieves alone. Chromium, molybdenum, and nitrogen content push its resistance to chloride attack well past what standard duplex or austenitic grades offer, which matters directly in seawater and sour gas service. Tensile and yield strength run close to double that of 300-series stainless steel, so components can often run thinner without sacrificing structural capacity. That combination of corrosion resistance and mechanical strength is why this grade holds up through long service life in offshore, marine, and process environments where replacement isn't a simple job.

Features & Benefits

Pitting resistance stands out as the defining property of this grade, backed by a PREN value above 40 that keeps localized corrosion from starting even in chloride-saturated water. Crevice corrosion resistance follows the same chemistry, protecting bolted and gasketed joints where stagnant fluid tends to concentrate attack. Stress corrosion cracking resistance matters most in hot chloride service, where standard austenitic bars would fail well before this grade shows distress. Mechanical strength runs high enough to reduce section size on many designs, and weldability stays good using matched filler metal. Fatigue resistance and dimensional stability round out the mechanical profile, supporting long operational life with low maintenance once installed.

 

Manufacturing & Quality Control

Every bar we ship goes through PMI testing to confirm alloy identity before it leaves the yard, followed by ultrasonic testing to check for internal defects along the full bar length. Hardness testing and chemical testing verify the material sits within specification, while mechanical testing confirms tensile and yield properties meet the required standard. Dimensional inspection catches any bar outside tolerance before packing begins. Third-party inspection through agencies such as SGS, BV, or TUV is available on request for projects that require independent verification alongside our own quality control records.

Packaging & Export

Round bars ship in wooden boxes or on wooden pallets, built to survive sea and air freight without damage to threads, ends, or surface finish. Export-worthy packaging includes HDPE wrapping for corrosion protection during transit and end caps for thread and bevel protection where applicable. Every shipment carries clear marking and traceability back to the original heat number, so buyers can match delivered material against mill certificates. We ship worldwide, with documentation prepared to match each destination country's import requirements.
