  1. Fabricating Duplex Stainless Steel

    Duplex Stainless Steels are growing at a high rate. It is important to understand how they differ from the more familiar stainless steels and how these differences affect the fabrication methods and parameters 

  2. Getting the Best out of Stainless Steel

    Stainless steel is a great material to work with. As with all materials you need to know how to treat it correctly for maximum cost effectiveness. This article summarises the typical pitfalls and remedies.

  3. Heat tint (temper) colours on stainless steel surfaces heated in air

    A colour chart is shown for guidance on exposure temperatures on 1.4301 (304) type. The factors affecting the degree or depth of colours formed are outlined. These include steel composition, atmosphere, time and surface finish.

  4. Pickling - State of the Art 2007

    An up to date review of pickling processes for stainless steel including immersion, spray, localised and anodic. It emphasises the benefits of pickling on the corrosion resistance of stainless steel. Author - John Swain of Anopol first published in Stainless Steel Focus Issue 03/2007.

  5. Post weld cleaning and finishing of stainless steels

    Should heat tint discolouration in the heat-affected zone of stainless steel welds be removed? In cases where the application involves an 'aqueous' corrosion hazard, the local reduction in sub-surface chromium can affect the corrosion resistance of the steel. The removal of weld heat tint from stainless steel fabrications using acid pickling or electrolytic methods not only improves the overall appearance but is vitally important for restoring the full corrosion resistance of the finished product. As a general rule, if you can see a discolouration on the surface due heat tint, this should be removed as part of good post weld cleaning practice for any stainless steel welded joints. (37)

  6. Practical Advice on Post Weld Treatment - Beware the Shoddy Finish

    Practical advice on the "hows" and "whys" of post weld surface treatments. Why removal of weld heat tint should be be the norm for stainless steel.
