- ElectropolishingThe electropolishing process smooths and streamlines the microscopic surface of a metal object. As a result, the surface of the metal is microscopically featureless, with not even the smallest speck of a torn surface remaining.
- How is Electropolishing Accomplished?How is Electropolishing Accomplished? In basic terms, the object to be electropolished is immersed in an electrolyte (typically phosphoric and sulphuric acid) and subjected to a direct electric current.
- Benefits of ElectropolishingDelstar's electropolishing services provides a number of features including better physical appearance, enhanced mechanical properties, better corrosion resistance and ease of cleaning.
- Metals that Can Be ElectropolishedMost metals can be electropolished successfully, but the best results are obtained with metals with fine grain boundaries that are free of non-metallic inclusions and seam, which makes stainless steel an ideal alloy for electropolishing.
- Characteristics of the Electropolishing ProcessA smooth, highly reflective electropolished surface is determined to a large extent by the surface conditions of the metal and the process controls.
- Good vs. Bad ElectropolishingHigh quality electropolishing begins with materials possessing superior electropolishing properties. Quality materials, coupled with proper techniques and conditions, generally will yield superb results.
- Applications GuideElectropolishing Reactor Vessels, Heat Exchangers, Mixers, Agitators, and Storage Tanks; extends operating times and reduces wear and tear on parts and reduces adhesion and contamination on the surfaces of process equipment.
- How to Specify ElectropolishingDelstat Standards of Quality - There are four primary and generally accepted finish standards for electropolishing.
- Electropolishing StandardsDelstar has led the industry's response to establish nationally accepted standards by establishing the Electropolish Finish Standards (EFS). Each standard contains specifications in order to enable customers to accurately specify the final finish desired
- Electropolishing User's GuideDelstar Metal Finishing, Inc.'s User's Guide to Electropolishing summarizes much of what has been written about electropolishing in textbooks, magazines, technical journals and handbooks, and it is believed to be accurately represented.
- PassivatingPassivation of stainless steel is done to make the surface more passive and corrosion resistant.Passivating creates a surface film that causes the surface to lose its chemical reactivity.
- Metal PicklingDelstar has some of the largest pickling tanks in North America. We can pickle or passivate any part that can be transported to our facility.
- Stainless Steel PicklingThe most common application for stainless steel pickling is “pickle/passivate” by Delstar. This is our “one-step” process which removes heat tint and weld scale while simultaneously passivating the surface of the parts being processed.
- Carbon Steel PicklingDelstar offers carbon steel pickling, cleaning and oiling services. From carbon steel vessels to carbon steel piping,
- Chemical CleaningDelstar provides a variety a chemical metal cleaning services to fit your needs. Whether you need a simple degreasing or critical cleaning for oxygen service, Delstar can get the job done.
- Mechanical PolishingMechanical polishing covers grinding, polishing and buffing - all processes for improving the surface conditions of a product for decorative or functional purposes.
- Buffing & GrindingBuffing is usually a final process using abrasives or abrasive compounds that adhere loosely to a flexible backing, such as a cloth wheel. Buffing is used to generate extremely fine surfaces that match those associated with honing and lapping.
- Protective CoatingsDelstar offers zinc phosphate protective coatings and sandblasting to a wide range of customers and industries.
- SandblastingDelstar offers aluminum oxide and glass bead blasting and blast-cleaning services to a wide range of industries and customers.
- On-Site ServicesDelstar offers an extensive line of on-site (“in-situ”) services. Our experienced and qualified mobile technicians know how to get the job done right.
