Duplex 2205 / 2507 / S32550 / S32101 Stainless Steel Plate Thickness 3.0-30.0mm Hot Rolled

Duplex 2205 / 2507 / S32550 / S32101 Stainless Steel Plate – Thickness 3.0–30.0 mm – Hot Rolled

Product Overview

We supply a comprehensive range of hot-rolled duplex stainless steel plates in four key grades:

• 2205 (UNS S32205 / S31803, EN 1.4462) – Standard Duplex
• 2507 (UNS S32750, EN 1.4410) – Super Duplex
• S32550 (UNS S32550, EN 1.4501) – Super Duplex (Ferralium® 255 equivalent)
• S32101 (UNS S32101, EN 1.4162) – Lean Duplex

Available in thicknesses from 3.0 mm to 30.0 mm, these plates are ideal for demanding applications in oil & gas, chemical processing, marine engineering, desalination, and infrastructure, where high strength, corrosion resistance, and cost efficiency are critical.

All plates are hot-rolled, solution-annealed, and rapidly quenched to ensure optimal dual-phase microstructure (ferrite + austenite), maximizing mechanical performance and resistance to pitting, crevice corrosion, and stress corrosion cracking (SCC).

Grade Comparison at a Glance

PREN = %Cr + 3.3×%Mo + 16×%N – Higher PREN = better pitting resistance.

Chemical Composition (Typical %)

Note: S32101 replaces expensive nickel with manganese and nitrogen—ideal for cost-sensitive structural uses.

Mechanical Properties (As per ASTM A240 / EN 10088-2)

All grades exhibit excellent toughness down to -40°C (with controlled ferrite content).
