Hardfacing Powders are manufactured to have the precise size, shape, and chemistry required for optimal thermal spraying characteristics. Our powders are available in a wide variety of alloys to give the workpiece desired finished qualities - whether it’s good machinability, abrasion resistance, corrosion resistance, ductility, hardness, or high strength. No matter the application, we have a powder that can be manufactured to your exact specifications and meet your coating needs. Hardfacing Process Hardfacing or surface coating is a process of spraying or welding metallic powders onto a workpiece or substrate to give it a specific hardness, wear resistance, or corrosion resistance. This process requires the appropriate alloy and particle size distribution for a specific deposition technology. Appropriately selected powders yield the best properties and manufacturing efficiencies.

Fine Tubes manufactures a range of specialist stainless steel tubes used to produce high-performance and ultra high-performance liquid chromatography (HPLC and UPLC) columns. Our tubes are components in both liquid and gas chromatography columns which are used for analytical and preparative processes across the fields of biochemistry and analytical chemistry. Tightest Tolerance Control The control process during manufacture of these tubes is critical to meet the highest specifications demanded in this area. The percentage Cross Section Area Reduction (% CSAR) through pilgering and drawing is specific to each product’s dimensions and specifications. Surface Finish The ID surface finish is further refined by passivation, polishing or electro polishing processes. OD surfaces are finished down to 0.1μm (0.25μ") and ID down to 0.16μm (0.40μ") and 0.08μm (0.20μ") with electro polishing. Please note that we have a minimum order value of £10,000.
