Product Description

ERNiFeCr-1

1. This exceptional nickel-based welding wire, engineered from the Ni-Cr-Fe-Mo-Cu system, is meticulously designed for high-performance tasks, thriving in corrosive and extreme thermal environments. It proudly belongs to the AWS classification A5.14 ERNiFeCr-1 and is synonymous with SNi8065 (ISO 18274) and NiFe30Cr21Mo3 (European standard), ensuring global compatibility and recognition.
Key Advantages:
Corrosion Resistance: This welding wire excels in reducing media, such as sulfuric and phosphoric acids, and demonstrates superior resistance to stress corrosion cracking, pitting, and crevice corrosion, making it ideal for challenging environments.
Thermal Stability: It remains mechanically robust, maintaining its integrity even from cryogenic levels up to an impressive 900°C.
Versatility: Perfectly suited for welding dissimilar metals, such as nickel alloys to steel, it is also an excellent choice for cladding operations, offering flexibility and reliability.
2. Chemical Composition
ERNiFeCr-1's carefully balanced composition (see Table 1) is optimized for superior weld integrity and performance:
High Nickel (38-46%) and Iron (≥22%): These elements form a ductile matrix, carefully balancing thermal expansion and strength for optimal results.
Chromium (19.5-23.5%) and Molybdenum (2.5-3.5%): These enhance oxidation resistance and provide stability in environments containing chlorides and sulfides.
Low Carbon (≤0.05%) and minimal impurities are ensured to reduce intergranular corrosion risks, thereby enhancing durability.

Source: 3. Mechanical Properties
As-Welded Performance:
Tensile Strength: ≥550 MPa, ensuring it meets the rigorous AWS A5.14 minimum standards.
Elongation: Ranging from ~25-34%, this demonstrates excellent ductility, crucial for demanding applications.
Impact Toughness: Retains its properties admirably even in sub-zero environments, such as those found in cryogenic storage tanks.
4. Technical Standards and Certification
Governed by:
AWS A5.14/ASME SFA-5.14: These standards mandate stringent chemical and mechanical specifications for quality assurance.
ISO 18274: Ensures global standardization with SNi8065, reflecting international acceptance and reliability.
F-Number 45 (ASME IX): This qualifies welding procedures for critical applications such as pressure vessels.
Quality Control: A rigorous process requiring Material Test Certificates (MTC) and passing RT/PT nondestructive testing to ensure reliability and safety.
5. Applications
Primary Use: Ideally suited for welding INCOLOY 825 (UNS N08825) and similar Ni-Fe-Cr-Mo-Cu alloys, ensuring compatibility and performance.
Critical Industries:
Petrochemical: Essential for reactors and acid-processing equipment where durability is key.
Nuclear: Used in steam generator tubes and pressure vessels, highlighting its resilience and safety in high-stakes environments.
Aerospace: Perfect for turbine components that are frequently exposed to thermal cycling, ensuring reliability and longevity.
6. Welding Process Guidelines
Methods:
TIG (GTAW): Employs 100% argon shielding, making it ideal for precise joints, such as thin tubing, where accuracy is paramount. Ideal for precision joints (e.g., thin tubes), TIG welding with 100% argon shielding ensures superior weld quality.
MIG (GMAW): Elevate your welding prowess with superior techniques for deeper penetration in thicker sections by utilizing a 75%-25% argon-helium blend. This potent combination is engineered to ensure robust weld quality and fortify structural integrity.
Parameters Overview: Gain insights into the specifics by consulting Table 2 for a comprehensive breakdown of detailed specifications.
Preheat/Cleaning: Achieving optimal welding results starts with an immaculate surface. Eradicate traces of oil and oxides through meticulous mechanical or chemical cleaning methods, ensuring a pristine foundation for superior welding outcomes.
Interpass Temperature: Vigilantly maintain a temperature of ≤150°C to prevent carbide precipitation, which could potentially compromise the weld's integrity, ensuring a flawless welding process.

7. Procurement and Handling Guidelines
Packaging: Our product comes in coils and spools, with diameters ranging from 0.8 to 5.0 mm, ensuring versatility for various applications. Available in manageable 10-25 kg units, designed for effortless handling and convenient storage.
Storage: Preserve the highest quality of welds by storing in a dry environment with humidity levels maintained below 60% to prevent moisture absorption.
8. Common Challenges & Their Effective Solutions
Porosity: This issue often arises from gas impurities. Utilize high-purity argon (99.99%) to eradicate impurities, ensuring impeccable and flawless welds.
Hot Cracking: Mitigate the risk by employing low heat input and minimizing joint restraints, thereby maintaining the integrity of the weld.
