INCO-WELD® 686CPT® Filler Metal (ERNiCrMo-14)

Specification

ERNiCrMo-14 is a 686 Ni-Cr-Mo alloy with the highest content of all Ni-Cr-Mo alloys. It is designed for welding UNS NO6022(2.4602), UNS NO6059(2.4605), UNS N10276(2.4819) and biphase. Super duplex and super austenitic stainless steel with TIG, MIG and SAW welding processes. The alloy is also used for welding cladding on parts exposed to acidic and acid-chloride environments. The high alloy content, results in high-strength welding materials with excellent corrosion resistance, especially pitting and slot corrosion. The material is thermally unstable at temperatures above 1200°C(2192°F), resulting in a high risk of intermetallic phases after welding. Ernicrmi-14 has the best corrosion resistance in most applications and is particularly suitable for the weld cover surface treatment of boiler tubes in waste power generation boilers. In addition, the material can be used in petrochemical, chemical, oil and gas and Marine industries

L605 is a cobalt-based superalloy, also known as Haynes 25. L605 wire is a specific form of this alloy, where L605 is drawn down to a smaller diameter and supplied in the form of a thin, continuous strand or wire spools.

Here are some key features and applications of L605 wire:

• High-temperature strength: L605 wire exhibits excellent strength at elevated temperatures, making it suitable for applications in high-temperature environments such as gas turbines and aircraft engines.
• Oxidation resistance: This alloy demonstrates good resistance to oxidation and other forms of high-temperature degradation, which helps protect the wire from environmental damage in high-temperature applications.
• Corrosion resistance: L605 wire offers good corrosion resistance, making it suitable for use in aggressive environments, including those containing sulfuric acid and other harsh chemicals.
• Wear resistance: The alloy’s hardness and wear resistance make L605 wire suitable for applications where the wire will encounter abrasive conditions or frictional wear.
• Biocompatibility: L605 wire has been used in some medical applications, such as certain types of surgical implants, where its biocompatibility and corrosion resistance are essential factors.
• Electrical and thermal conductivity: The alloy’s electrical and thermal conductivity properties make it useful in certain electrical applications, including spark plug electrodes and resistance heating elements.
• Weldability: L605 wire is weldable using standard welding techniques, allowing for ease of fabrication and joining with other components.
• Aerospace and industrial applications: L605 wire finds use in aerospace components, power generation equipment, chemical processing, and various high-temperature and corrosive environments where its exceptional properties are valued.

As with any material, the choice of L605 wire depends on the specific requirements of the application and the environmental conditions it will encounter. It is commonly sought after in industries where high-temperature and corrosion-resistant properties are crucial, making it an integral part of cutting-edge engineering and manufacturing solutions.
