EuTroLoy 16457

Product catalog summary

Overview: EutroLoy 16457 is a composite alloy powder designed for the Plasma Transferred Arc (PTA) process, specifically for surfacing extrusion screws in plastic and rubber processing. It enhances wear resistance through tungsten carbide addition, offering excellent erosion, abrasion, and corrosion resistance, and is ideal for applications requiring extended service life.

Description: EutroLoy 16457 is part of a specialized range of alloys for coating extrusion screws via PTA. It features controlled chemistry and particle size for consistent high-quality coatings, significantly improving screw life by 2-3 times due to its high abrasion resistance and corrosion resistance.

Typical Applications: This alloy is suitable for PTA welding of various steels and castings, including decanter and transport screws, extrusion screws in plastic and rubber processing, and down-hole drilling components.

Procedure for Use: The process involves removing damaged material, cleaning the welding area, and matching heat input to component dimensions. It is crucial to maintain low dilution with the base metal and allow slow cooling post-welding. Amperage and voltage should be minimized to preserve tungsten carbide integrity while ensuring a strong bond.

Coating Properties: The coating has a hardness of 45 HRC, a deposit density of 10.0 g/cm³, and a particle size range of -180 + 63 µm. It can withstand temperatures up to 650°C and has a deposition rate of 2.27 - 9 kg/hr. The typical chemistry includes a nickel matrix with chrome, boron, silicon, iron, carbon, and 15% cast tungsten carbide.

Health & Safety: Standard welding safety practices should be observed, including eye, hearing, skin, and respiratory protection. Refer to ANSI Z49.1:2012 for general welding safety guidelines. Ensure familiarity with local safety regulations and obtain the Material Safety Data Sheet (MSDS) from Eutectic.

Finishing: EutroLoy 16457 coatings can be finished by grinding to achieve a high surface finish.

Statement of Liability: The technical information provided is without warranty, and users must evaluate the suitability and compliance of the product for their specific applications.
