Grade Overview

What are RDSO Spec X2CrNi12 CK201 Plates?

X2CrNi12 RDSO Spec plates are ferritic stainless steel plates manufactured according to RDSO specifications. Made with chromium as the main alloying element and minimal nickel, they offer excellent corrosion resistance and good weldability. They are particularly suited for heavy engineering, railway and infrastructure applications due to their ferritic microstructure.

Composition Analysis

Metallurgical Characteristics of X2CrNi12 RDSO Spec Plates

Each element in X2CrNi12 plays a precise role in delivering excellent corrosion resistance, toughness and structural performance.

Cr
Chromium
Provides corrosion and oxidation resistance and improves hardness.
Ni
Nickel
Enhances toughness and overall corrosion resistance.
