Thread galling mainly occurs with fasteners made of aluminium, titanium, stainless steel, and other alloys which self-generate an oxide surface film for corrosion protection. Galling can occur when excessive pressure is used to tighten a nut onto a thread. In our experience this is observed most on assemblies utilising Nyloc nuts.اقرأ أكثر
The two most commonly produced grades of stainless steel are 304 (known as 'A2') and 316 (known as A4). Both of these grades will offer excellent corrosion resistance, cleanability, and the ability to handle extremely low (cryogenic) and high temperatures.اقرأ أكثر
