ER316L-Stainless Steel Wire ‌

Technical Compliance‌: AWS 5.14 Class ER316L / ASME SFA 5.14 Class ER316L

Product Overview

ER316L is a superior low-carbon austenitic stainless steel welding wire enhanced with molybdenum, designed for Gas Metal Arc Welding (GMAW/MIG) and Gas Tungsten Arc Welding (GTAW/TIG) processes. This wire combines excellent low-temperature impact toughness with outstanding corrosion resistance, making it particularly suitable for pressure vessel applications in demanding environments.

Key Features & Benefits

• Molybdenum Enhancement: The deliberate Mo addition provides enhanced resistance to pitting and crevice corrosion in chloride-containing environments, surpassing the capabilities of standard 308/309 series wires.

• Ultra-Low Carbon Content (<0.03%): Prevents carbide precipitation during welding, eliminating intergranular corrosion susceptibility and ensuring long-term structural integrity.

• 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.

• Excellent Low-Temperature Impact Toughness: Maintains remarkable mechanical properties and ductility even in cryogenic conditions as low as -196°C (-321°F).

• Superior Corrosion Resistance: Excellent resistance to a wide range of corrosive media, including acids, alkalis, and chloride solutions.

Technical Specifications

• Standards Compliance: Meets AWS A5.18 ER316L specifications.

• Available Diameters: 0.8mm, 1.0mm, 1.2mm, and 1.6mm to accommodate various application requirements.

• Chemical Composition:

• Carbon: ≤0.03%

• Chromium: 18-20%

• Nickel: 11-14%

• Molybdenum: 2-3%

• Packaging: Supplied in 2kg spools, 5kg spools, or 15kg reels for operational flexibility.

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.

• Low-Temperature Applications: Ideal for cryogenic storage tanks, LNG equipment, and industrial refrigeration systems operating in extreme cold conditions.

• Marine and Offshore: Components exposed to saltwater and harsh marine environments where chloride-induced corrosion is a concern.

• Architectural and Structural: Critical components in corrosive environments where both strength and durability are paramount.

Important Usage Guidelines

1. Shielding Gas Requirements:

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

• Maintain gas flow rate at ≥20 L/min for 1.2mm and 1.6mm wire diameters, adjusting accordingly for other sizes to ensure adequate coverage.

2. Environmental Conditions:

• Provide adequate wind shielding around welding areas using temporary barriers or permanent enclosures.

• Avoid outdoor welding in windy conditions unless proper windbreaks are established to maintain shielding gas effectiveness.

3. Surface Preparation:

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