In our work shop we never stocked nickel plated brass press studs as they look exactly the same as stainless steel press studs.


In all of our applications we always used stainless steel press studs when ever press studs were required, such as on boat canopies etc. stainless steel press studs can handle extreme weather condition such as marine situations.


NOTE: Some customers have questioned the validity of my stainless steel press studs stating they were not stainless steel because they can be picked up by a magnet. It is an old wife's tale that stainless steel can not be magnetised. There is much scientific literature on stainless steel and magnetism which can be Googled.

The most popular stainless steel are Type 304, 306 which contains approximately 13 to 18 percent chromium and 8 percent nickel. At room temperature, the thermodynamically stable crystal structure of 304, 306 stainless steel is bcc; nevertheless, the alloy's nickel concentration, as well as the small amounts of manganese (about 1 percent), carbon (less than 0.08 percent) and nitrogen (about 0.06 percent), maintains an fcc structure and therefore the alloy is nonmagnetic. If the alloy is mechanically deformed, i.e. bent, at room temperature, (Our press studs are cold formed under extream pressure) it will partially transform to the ferritic phase and will be partly magnetic, or ferromagnetic, as it is more precisely termed.

Popular ferritic stainless steels are iron-chromium binary alloys with 13 to 18 percent chromium. These alloys are ferromagnetic at room temperature. Like all ferromagnetic alloys, when heated to a high enough temperature--their Curie temperature--the ferritic stainless steels lose their ferromagnetism and become paramagnetic--that is, they do not retain their own magnetic field but continue to be attracted to external ones.

BEWARE

On aluminium boat windscreens, applying nickel plated brass press studs will quickly erode the aluminium away causing expensive replacement or repair of the windscreen frame. This is why we never stocked other than stainless steel press studs, even will all our experience we could not tell them apart from the cheapies.


Where this has happened and you would like to remove and replace your old studs with stainless steel press studs – contact me and I will be able to give you some advice as to how this may be done.
