A2-70 stainless steel is a commonly used fastener material whose main features are good corrosion resistance and high strength. A2-70 Nut Set is made of 304 stainless steel, and the "A2" in its mark "A2-70" represents the material type, which is 304 stainless steel, which is an austenitic stainless steel that is usually non-magnetic. The number "70" indicates that its tensile strength is 700MPa.
A2-70 Nut Set has very good corrosion resistance and are suitable for a variety of environments, especially in humid and corrosive.
A2-70 Nuts are mainly used in situations where corrosion resistance is required, such as the fixation of body panels, bumpers, fenders, door handles, locks, lamps and other components.
In terms of mechanical properties, the strength of A2-70 bolts exceeds ordinary grade 4.6 and grade 5.8 carbon steel bolts, but is not as strong as grade 8.8 alloy steel bolts. Therefore, A2-70 bolts can replace grade 4.6 and 5.8 bolts, but when it is necessary to replace grade 8.8 bolts, the mechanical load must be considered.
A2-70 bolts are mainly used in situations where corrosion resistance is required, such as the fixation of body panels, bumpers, fenders, door handles, locks, lamps and other components. It is also suitable for non-mechanically loaded engine components that require a simple clamping action, such as intake and exhaust manifold accessories, auxiliary accessories, pipe clamps, flange connections, etc.
However, A2-70 bolts are not suitable for use in heavily loaded machinery or structural areas, such as areas directly loaded on the suspension, areas directly loaded on the steering column and connecting rods, active engine accessories and power transmission components, etc.
