18-8 Stainless Steel Bolts are also known as A2 or Type 304 or 18/8 and the reason for this is because they contain roughly 18% chromium and 8% nickel. The reality is that type A2 stainless steel is also referred to as Type 304 stainless steel. A2 stainless steel bolts, such as A2-80 Bolts are austenitic steel and they are non-magnetic. As they contain chromium in them, they can resist oxidation and corrosion, but they can tarnish.
A2 70 Bolts are a good idea to use when there is the need to minimize the risk of corrosion and these kinds of bolts are commonly used in food and dairy production environs, as well as in households. When thinking of A2-70 Bolts vs 8.8, it is crucial to take note that the A2 grades of stainless steel are available in 3 property classes and that the Stainless Steel 304 Bolts can be cold worked and A2 8.8 Bolt is of high strength, though the most commonly used of the two is the A2-70 Bolt.
