	Each month, SCS UPDATE brings readers the latest news on technical developments, SCS producers and applications. Some readers have asked where they can see an inventory of all previous articles, especially application stories like paint prep tips or welding test results. Readers have also asked how to find out about specific parts manufactured from SCS. In response to these requests, we've made some upgrades to the SCS web site, www.scsprocess.com, while this issue provides the requested inventory of past application articles - our "Application Highlights."

						We also felt it was important that our readers know what SCS' limitations are . . . the manufacturing processes where it has not performed as well as we had hoped. The second article of this month's issue, "Application Limits" discusses these areas. As for an inventory of past SCS UPDATE articles, you can now access the full article index through the "SCS Library" link of the web site. A few seconds after that page loads, a window opens containing links to all past SCS UPDATE articles. Try it now. We've also compiled a list of the various parts being successfully manufactured from SCS. That list now resides on the SCS web site and is accessed through the "Applications" link. The graphic on the left shows this page and you can access it now
	The new link on the 'SCS Library' page lists many parts currently being       manufactured with SCS. Photos of some parts are viewed by clicking       on part names that are hot-linked. The list will be updated regularly.       through this link.       Keep in mind that the list of parts       shown is the proverbial "tip of the       iceberg". The complete list would be much larger, but we don't know how much of the SCS processed for our service center partners ultimately is used. (Even when we are told the nature of the part and customer making it we follow a strict policy of not revealing the identity of the manufacturer or the service center supplying SCS to them.) The table below contains links to previous UPDATE articles, arranged by application category. We hope you find it a useful way to catch up on items you may have missed, and please contact us if you have questions on any of these articles or need further information.

	While numerous SCS advantages have been documented through testing and applications, there are some processes where SCS is not a good fit or has not yet been tested extensively enough to offer conclusive results. Potential users need to be aware of these limitations, so we provide a brief explanation of each below: Prepainting Coils. Coils of SCS prepaint beautifully; however, when the painted material is subsequently formed or bent, some 'powdering' of the surface scale can occur on inner radii. This degrades paint adherence and protection. Note that this same scale powdering can occur with bare SCS material, but the bent bare part can be cleaned with a lean alkaline cleaner to remove the powdered scale or it can be painted over, as the extent of powdering is minor. SCS parts painted AFTER bending/forming achieve the generally good corrosion resistance we have come to expect . Continuous Inline Galvanizing. SCS performance here seems to suffer from the same issue as prepaint coils; however, there are some important exceptions:    - SCS which is first cold reduced and then galvanized has demonstrated excellent adherence of the zinc coating      even with aggressive bending (see photo).    - SCS parts which are batch galvanized (hot dipped) show excellent adherence of the zinc coating. Porcelain Enamel Coating. This process works best with a rougher surface than SCS offers, plus the high heat needed for 'baking' porcelain parts seems to cause some scale loosening which degrades the finish. Deep Draw with Spinning. This challenging process is used to manufacture wheel rims. The aggressive draw and subsequent spinning disrupted scale from the SCS, which mixed with the lubricant to create an oily soot. This also complicated welding of the part. SCS has performed well in other spinning applications, as well as stand-alone deep draw applications, but aggressive drawing processes - especially combined with other forming - may require different (dry) lubricant and other adaptations to produce acceptable results. In some cases the draw will simply be too deep to avoid significant scale disruption. Electrolytic Plating. Tests with zinc plating showed it was more difficult to achieve a high quality coating with SCS than with P&O. Why? SCS retains a very thin layer of oxide -- a ferrous organic material. You can't electrolytic plate organic material. Then how did our featured SCS user Stan Vallis obtain such good zinc plating results? Top flight platers offer hydrochloric acid pickling of parts, which is needed to remove any scale from hot-rolled material prior to plating. The pickling works for SCS too -- remove its thin layer of scale and it plates very well. Salt Spray Corrosion Tests. We've reported in past UPDATE articles, and in our Metallurgical Test Results, repeated success with SCS painted parts that have undergone salt spray testing. We have also seen great results from impact, cyclic and humidity tests. SCS customers have, likewise, obtained excellent results overall, but there have been a few exceptions in the salt spray test category. We are studying these rare cases and also conducting the most extensive corrosion testing on painted SCS to date. We hope to report on the results of these tests in the third quarter of this year. We realize that as SCS usage continues to grow, we have an obligation to inform both sellers and users of its limitations, as well as its advantages. SCS UPDATE will continue to be the primary means for getting this information to you, so we encourage you to read every issue you receive. New SCS Brochure for Tubers The success of recent tube and pipe production trials (see May 2006 issue) confirms the value of SCS to this important industry segment. To assist our sales partners and licensees in marketing SCS to their tube/pipe customers, we've jut completed the new SCS sales brochure shown below. To obtain your copy, either by download or ordering printed copies, use the SCS downloads link. SCS in the Press SCS Licensee Layhill Processing is featured in July's Metalforming magazine.
