Tea-staining is a discolouration of the surface of stainless steel caused by mild corrosion This corrosion is cosmetic only and does not affect the structural performance of stainless steel. Having recently attended an ASSDA seminar on Preventing Coastal Corrosion, I would like to share some information on how to get the most out of your stainless steel and keep it looking [...]

To help you avoid the common mistakes made when specifying and using stainless fasteners, we have put together a short DOs and DON’Ts guide.
1. DO: Select the Right Grade
There are many different grades of stainless steel. The two commonly used grades are 304 and 316, with 316 being more corrosion resistant than [...]
Galvanic Corrosion is corrosion damage created when dissimilar materials are joined by a corrosive electrolyte. Galvanic Corrosion is a common type of corrosion found in Marine Environments. For example, two dissimilar metals such as Stainless Steel and Aluminium touching and an electrolyte such as salt-water or even rain [...]
Stainless fastener engineers and customers will both pay testament to the importance of lubricating stainless steel threads. This is to avoid the problem of ‘galling’, which is when two threads bind together and seize. It is a fairly common when using stainless steel fasteners, particularly with larger threads, say M16 and larger, and also with [...]
Jim, our MD, is a big fan of stainless steel. He says that there was the stone age, then the iron age, and now we are in the ‘stainless age’ (and long make it last!). This year marks 100 years since stainless steel was first discovered. To mark this centenary, the International Stainless Steel Forum [...]
As Grahame Ansley, one of Anzor’s directors likes to say, stainless steel is ‘stainless’ not ‘non-stain’.
Yes stainless steel is corrosion resistant, but depending on a range of factors – the grade, the environment, exposure to rainwater, the surface finish, etc; stainless steel products may be subject to ‘tea staining’ (surface rust) or rusting. Therefore [...]
