Whether you are looking to rebuild, customise, enhance or reduce weight on anything from a project bike, road bike or Superbike, look no further...These Quick Release D Ring Fasteners are made from high quality 316 grade Stainless Steel, benefits include greater strength and corrosion resistance, coupled together with stunningly good looks!Material Specification: 316 Stainless SteelStainless Steels are iron alloys with a minimum of 10.5% chromium with other elements (Nickel, Molybdenum, Titanium, Copper, Carbon, Nitrogen) added to enhance properties such as formability and strength. But it is the chromium-rich, oxide film that gives the corrosion resistance of stainless steel. This protective film is strong and chemically stable (i.e. passive) where there is sufficient oxygen on the surface. This strong protective film is extremely thin and will usually self repair if sufficient oxygen is available. Under certain conditions the passive state can be broken down and corrosion can result.
