ABOUT SCANACON (FOR INVESTORS, STUDENTS AND MEDIA)
“Steel” is a alloy predominantly comprised of iron and carbon. Carbon steel is a ubiquitous material, found in everything from civil construction and shipbuilding to automobiles and consumer appliances. The carbon steel industry is a global enterprise, with more than one billion tones of material produced annually.
Carbon steels, however, have their limitations. When specific applications require materials of greater strength, temperature or corrosion resistance, for instance, other iron based alloys, or metals are selected. Stainless steels, speciality nickel and chromium based alloys, and zirconium and titanium metals are examples of these materials.
Highly specialized to manufacture and expensive to produce, worldwide production of these materials is less than 5% of total carbon steel production. Aerospace, military, energy, petrochemical and nuclear industries are common areas where these materials see use. China, Korea, Japan, Taiwan, India, the United States and the European Union are the principal producing regions in the world. Asia alone accounts for approximately 65% of the world's production.
Scanacon is a speciality engineering and manufacturing company providing knowledge and technology for stainless steel, speciality alloy, titanium and zirconium producers and fabricators. Our focus is in the production area known as “finishing”. Finishing encompasses a variety of production activities, but are typically divided into “pickling”, “etching” or “chemical milling”.
During the production of stainless steels, speciality alloys, titanium and zirconium materials and fabrications, acids are used to either clean (“pickle”) or etch the surface of the material, or, in the case of chemical milling, remove minute amounts of material from complex fabrications that mechanical methods cannot achieve.
Finishing activities ultimately define the appearance and the metallurgical properties of the material. Stainless steels, for instance, cannot obtain their rust resistant properties unless cleaned in a solution of acid. Titanium, used in jet aircraft due to it’s superior strength to weight ratio is brittle and will crack unless finished in a solution of acid. As such, finishing activities are critical steps in the production and fabrication of these exotic and expensive materials.
Similar in how water used to wash dishes or laundry becomes dirty and must be disposed of, the acids used in the various finishing processes become contaminated over time and must be discarded as a hazardous waste. In addition to the problem of hazardous waste, issues of productivity and quality may arise as the acid solutions become contaminated.
For over 30 years we have manufactured equipment for the monitoring of the acid solutions to determine their usefulness, provide technology to clean and recycle contaminated acids, and engineer systems for containment, handling and storage of these acid solutions. Our knowledge and understanding of acid finishing is second to none. We have an installed base of hundreds of systems worldwide, and serve our customers with offices in China, Asia, the United States and Europe.
Scanacon brings value to our customers by optimizing and managing their acid finishing activities. Scanacon systems minimize the costs of the finishing process by reducing the quantity of acids and chemicals used, help the environment by recycling hazardous acid wastes, improve productivity, ensure the quality of the finished material, and minimize health and safety risks to the factory staff.
