ER2209 Duplex Stainless Steel Welding Rods – 2.4mm x 1000mm (1Kg Pack)

Core Specifications

Product Description

ER2209 welding rods are engineered for critical applications requiring superior corrosion resistance and mechanical strength. Designed for welding 22Cr duplex stainless steels in as-welded condition, these rods deliver exceptional performance in severe service environments. Each rod features individual stamping for traceability and quality assurance.

Key Features & Benefits

– Enhanced Corrosion Resistance: Superior resistance to stress corrosion cracking and pitting
– Optimized Microstructure: Balanced austenite-ferrite composition for durability
– Versatile Welding: Ideal for both homogeneous (22Cr duplex) and heterogeneous (other stainless/low alloy steels) applications
– Quality Assurance: Individually identified rods ensure batch consistency
– Cost-Effective Packaging: 1Kg pack with approximately 40 sticks for efficient inventory management

Applications

Suitable for welding wrought, forged, or cast 22Cr duplex stainless steels in:
– Chemical processing equipment
– Oil & gas pipelines
– Marine engineering
– Pressure vessels
– Desalination plants
– High-corrosion industrial environments

Performance Advantages

The weld metal maintains excellent mechanical properties with controlled ferrite content, ensuring compatibility with 2205 base metals. Recommended for applications requiring post-weld corrosion resistance without heat treatment.

Quality Assurance

Manufactured under strict quality control standards, each rod undergoes rigorous testing to ensure compliance with industry specifications. Our production process guarantees consistent chemical composition and weldability.
