Product Description for 420 SS Thermal Spray Wire for Arc Spraying

Product Introduction

420 SS (Stainless Steel) thermal spray wire is a high-quality material designed for arc spraying applications. Known for its excellent corrosion resistance, high hardness, and good wear resistance, 420 SS is a martensitic stainless steel that provides robust surface protection. This wire is commonly used in industries such as petrochemical, power generation, automotive, and marine to enhance the durability and lifespan of critical components. The 420 SS thermal spray wire is ideal for applications requiring a hard, wear-resistant coating with moderate corrosion resistance.

Surface Preparation

Proper surface preparation is crucial to achieving optimal results with 420 SS thermal spray wire. The surface to be coated should be meticulously cleaned to remove contaminants such as grease, oil, dirt, and oxides. Grit blasting with aluminum oxide or silicon carbide is recommended to achieve a surface roughness of 50-75 microns. A clean and roughened surface enhances the adhesion of the thermal spray coating, leading to improved performance and longevity.
