Product Overview

What are Zeron 100 Threaded Rods?

Zeron 100 threaded rods are high-alloy super duplex stainless steel fasteners manufactured from UNS S32760 bar stock, conforming to ASTM A276 and ASTM A479. With a dual-phase microstructure and a PREN (Pitting Resistance Equivalent Number) of 40+, Zeron 100 threaded rods deliver exceptional resistance to chloride-induced pitting, crevice corrosion, and stress corrosion cracking in aggressive environments.

These rods are specified for critical bolted joints in offshore, desalination, and chemical processing applications where standard duplex or austenitic stainless steels fail. Zeron 100 threaded rods are NORSOK M-650 and NACE MR0175/ISO 15156 compliant, making them the preferred choice for sour service and seawater-exposed bolted assemblies.

Material Chemistry

Zeron 100 Chemical Composition

Zeron 100 Threaded Rods are manufactured from a high-alloy ferritic-austenitic steel containing chromium (24–26%), molybdenum (3.5–5%), and nitrogen (0.24–0.32%) per ASTM. These precise elemental limits produce PREN ≥ 40 — confirming seawater pitting immunity — and deliver the 550 MPa minimum yield strength required for NORSOK M-630 subsea qualification.

Why Zeron 100 Alloy Composition Matters for Threaded Rods

High Chromium & Molybdenum — Superior Pitting Resistance
The elevated Cr (24–26%) and Mo (3–4%) content gives Zeron 100 threaded rods a PREN >40, ensuring outstanding resistance to pitting and crevice corrosion in seawater, brine, and chloride-laden process streams.
Copper & Tungsten — Acid & Brine Durability
Copper and tungsten additions enhance resistance to sulphuric acid and hot brine, making Zeron 100 rods ideal for desalination, mining, and chemical plant bolting.
Nitrogen — Strength & SCC Resistance
Nitrogen increases yield strength and improves resistance to chloride stress corrosion cracking, critical for threaded rods in offshore and sour service environments.
