sheet, plate, bar & tube, but all finishes may not be available on all forms. 7 Finish. Results: 63-64% reflectivity on Super #8 mirror polished stainless and 56-57% reflectivity on Super #8 mirror polished stainless with titanium nitride (gold color finishes). The reflectivity of mechanically polished (MP) stainless steel containing 18% Cr and 10% Ni was found to be 8–10% lower than with the same material polished electrochemically (EP) at 80°C in a solution of 60% H 3 PO 4, 20% H 2 SO 4, and 20% H 2 O. I'm told these number is below regular glass mirrors...but very good for mirror polished stainless surface. Stainless steel mirrored cladding. Surface quality is close to a glass mirror, but reflectivity wise, it tested at only 62-63%. If a higher reflectivity is required, the finisher can switch to a 400 grit drum or a super fine belt. No. I'm told these number is below regular glass mirrors...but very good for mirror polished stainless surface. Index of Refraction values (IOR) - For use with 3d modeling / rendering and animation applications. Stainless steel is a very versatile cladding material because of its corrosion resistance properties and ability to accept a range of surface finishes. Many 3d applications these days allow you to input actual IOR values in order to achieve a more accurate representation of surfaces during rendering of your 3d models. This easy-to-clean finish has a typical Ra between 0.05…0.1 micrometers. SPECULAR REFLECTANCE Stainless steel is polished by mills in a range of forms, e.g. Polished Stainless Steel, Electroless Nickel Coat (MIL-C-26074) Permanent Marker on Aluminum ... Total reflectance of Invar and stainless steel samples. Results: 63-64% reflectivity on Super #8 mirror polished stainless and 56-57% reflectivity on Super #8 mirror polished stainless with titanium nitride (gold color finishes). Material Reflection Factor (%) Aluminum coatings, matt: 55 - 56: Aluminum, anodised, matt: … Stainless steel is an alloy (a mixture of two kinds of metal) of steel and chromium. Enhancing the reflectivity of mirror polished stainless 1998. While stainless steel is not fully stain-proof, it is much more resistant to staining, corrosion, and rust than traditional steel. Over the past few years I have been collecting IOR (Index of Refraction) values I can find for use in 3d rendering applications. We specialize in mirror polished stainless steel sheets. In order for steel to be considered “stainless”, it must have a minimum of 10.5% chromium content by mass. No. 7 Finish has a high degree of reflectivity and a mirror-like appearance. used mirror polished stainless steel to present a high quality image. 4. Figure 4. This recent photograph shows that the sign has not lost any of its lustre. Background: The 6.433 triangles used for the exterior cladding It is very smooth and less likely to harbour airborne contaminants and moisture compared to any other mill finishes. Type of stainless involved are 304 and 316. Erected in 1929, the mirror polished stainless steel sign of this famous London Hotel, has been exposed to the elements for 70 years. Are there any ways to enhance the reflectivity of mirror polished stainless? 4 finish that has been polished to 320 grit is buffed for up to 10 minutes, but existing grit lines are not removed. In aggressive environments, such as in the nuclear or offshore industries, a correctly polished stainless steel surface has a better resistance to corrosion than a surface that is roughly or badly polished. A No. Total reflectance of various commercial and household blackout and baffling materials. The resulting stainless steel finish is capable of reflecting clear images. It is important, therefore, to … correctly polished stainless steel not only looks good but it helps to reduce the risk of bacteria being retained by the material.
