ER317L-Stainless Steel Wire ‌

Technical Compliance‌: AWS 5.14 Class ER317L / ASME SFA 5.14 Class ER317L

Product Overview

ER317L is a premium low-carbon austenitic stainless steel welding wire with strategic niobium (Nb) addition. Engineered for Gas Metal Arc Welding (GMAW/MIG) and Gas Tungsten Arc Welding (GTAW/TIG) processes, this wire delivers exceptional performance in both low-temperature and corrosive environments. The unique combination of niobium stabilization and optimal ferrite content makes it ideal for critical applications where corrosion resistance and structural integrity are paramount.

Key Features & Benefits

• Niobium (Nb) Enhancement: The deliberate Nb addition effectively prevents intergranular corrosion by stabilizing the microstructure against carbide precipitation.

• Ultra-Low Carbon Content (<0.03%): Minimizes susceptibility to intergranular corrosion and ensures long-term performance in harsh operating conditions.

• Optimal Ferrite-Austenite Balance: Contains carefully balanced ferrite content within the austenitic structure, ensuring superior weld integrity and exceptional resistance to hot cracking during fabrication.

• Superior Low-Temperature Impact Toughness: Maintains remarkable mechanical properties and ductility even in cryogenic conditions.

• Enhanced Corrosion Resistance: Provides exceptional protection against pitting, crevice corrosion, and general oxidation in aggressive chemical environments.

• Excellent Weldability: Produces smooth, spatter-free beads with minimal defects and easy slag removal, reducing post-weld cleanup time.

Applications

• Pressure Vessels: Critical for applications requiring both excellent corrosion resistance and superior low-temperature impact properties in chemical processing, petrochemical, and power generation industries.

• Chemical Processing Equipment: Tanks, reactors, and piping systems exposed to corrosive substances and requiring reliable long-term performance.

• Marine and Offshore Structures: Components subjected to saltwater, humidity, and harsh environmental conditions where corrosion resistance is critical.

• Cryogenic Applications: LNG storage tanks, industrial refrigeration systems, and components operating at very low temperatures.

Important Usage Guidelines

1. Shielding Gas Requirements

• Use CO₂ purity of 99.98% or higher to ensure weld integrity and prevent porosity or other weld defects.

2. Environmental Conditions

• Provide adequate wind shielding around welding areas using temporary barriers or permanent enclosures to maintain shielding gas effectiveness and weld quality.

3. Surface Preparation

• Thoroughly remove all oil, grease, moisture, and surface contaminants using appropriate solvents and mechanical methods before initiating welding operations.
