Anti-corrosion, anti-oxidation and increased material lifetimeSilcolloyTM improves corrosion resistance of stainless steel by up to 10x SilcolloyTM1000 formerly Silcosteel®-CRUS Patent 7,070,833112 Benner Circle | Bellefonte, PA 16823814-353-1778 | Fax 814-353-1697www.SilcoTek.comMethods available to control industrial corrosion are limited to corrosion-resistant alloys, barrier coatings, cathodic protection, and corrosion inhibitors. When properly applied, each method can be effective in slowing corrosion, but each has limitations as well. For example, some coatings are inexpensive, but require rigorous inspection and/or frequent reapplication. Corrosion-resistant alloys can provide exceptional protection, but can be prohibitively expensive. Some alloys require significant process redesign, increase operating cost, or generate hazardous waste.SilcolloyTM1000 is a proprietary (U.S. Patent #7,070,833), multilayer sil-icon, chemical vapor-deposited (CVD) coating, specifically designed to improve the corrosion resistance of steel, stainless steel, alloys, glass, and ceramics. The unique non line-of-sight CVD process produces a flexible amorphous silicon layer that diffuses into the metal lattice. The layer will conform to the most intricate surface while maintaining high dimensional tolerances. SilcolloyTM1000 will deform with tubing surfaces, allowing leak-free seals or radius bends.Independent Laboratory TestingSilcolloyTM1000 offers an order of magnitude or more improvement in corrosion resistance relative to existing processes.Corrosion testing of SilcolloyTM1000 treated 316L stainless steel and untreated 316L steel according to ASTM G 48, Method B2 (72-hour ferric chloride pitting and crevice corrosion testing), shows corrosion of the treated stainless steel is reduced by an order of magnitude, as measured by weight loss (Figures 1 and 2).1 Economical protection against corrosion is highly effective protection for equipment exposed to:• hydrochloric or nitric• marine environmentstreatment extends the lifetime of steel and steel alloy systems. High temperature capability and leak-free sealing capibility make it an ideal treatment for:• process tubing, fittings, valves, and reactors• gas transfer and delivery systems• nozzles• stack gas monitors• analytical testing equipment in harsh environmentsFigure 1 SilcolloyTM1000 treated stainless steel outperforms uncoated metal by an order of magnitude (ASTM G 48, Method B).Testing courtesy of Matco Associates.0 50 100 150 200 250Untreated 316 SSSilcolloy1000TMweight loss in grams per square meterSilcolloyTM1000Untreated 316 SSTesting of SilcolloyTM1000 treated coupons in neutral, acidic, and basic chloride solutions, according to ASTM G 61,1 shows SilcolloyTM1000 treatment reduces corrosion rates by an impressive 50x, compared to untreated 316L stainless steel.Improved Performance in Marine or Acidic EnvironmentsSilcolloyTM1000 treatment is effective in acidic or salt corrosive environments, in which the user demands extended service life for an existing process without using high-priced alloys. 4000-hour salt spray testing (salt spray accelerated weathering test ASTM B117) shows SilcolloyTM1000 treated stainless steel coupons exhibit no sur-face corrosion, while untreated coupons show surface corrosion and accelerated corrosion at the coupon hole (Figure 4). Neither coupons developed pitting over the test period.1SilcoTek treatments are available worldwide112 Benner Circle | Bellefonte, PA 16823814-353-1778 | Fax 814-353-1697www.SilcoTek.comSave Thousands with SilcolloyEstimated lifetime cost savings of a typical process system show SilcolloyTM treated sample lines, fittings and valves will save the user hundreds of thousands of dollars. While the initial cost of an unprotected stainless steel system is lower than a comparable SilcolloyTM1000 treated system, the overall lifetime cost, considering replacement cost due to corrosion is nearly double that of a SilcolloyTM1000 treated system (see figure 5). Conversely, high performance alloy systems offer superlative corrosion performance, but the initial material cost can be up to six times higher than a comparable stainless steel system. SummarySilcolloyTM1000 treatment has extended the life of process systems in oil and gas production, oil refining, petrochemical processing, aero-space equipment, food and beverage processing, and laboratory testing facilities worldwide.Test data show that SilcolloyTM1000 treatment is effective in extend-ing the corrosion resistance of stainless steel process systems while reducing overall system maintenance cost. Because SilcolloyTM1000 treatment can be applied to a majority of existing process compo-nents, process equipment life is extended without significant re-engineering.References1. M. Zamanzadeh; G.
