The excellent mechanical qualities and corrosion resistance of stainless steel A2-70 fasteners make them perfect for many uses. Designed from austenitic, non-magnetic stainless steel grade A2-70, these fasteners are made from High tensile strength and durability guaranteed by this grade, corresponding with ASTM A193 and ASME SA193 standards. These parts are ideal for demanding industrial uses since the A2-70 fasteners classification shows that their minimum tensile strength is 700 MPa.
Stainless steel A2 70 fasteners have a balanced blend of chromium and nickel, giving exceptional resistance to oxidation and rust. Usually containing 18% chromium and 8% nickel, these fasteners have great performance in many conditions and non-magnetic qualities. To improve their qualities even more, they might include minute concentrations of additional elements, including silicon and manganese.
Vision Alloys offers a large spectrum of goods to satisfy various industrial needs as a top stainless steel A2-70 fasteners supplier in India and a leading stainless steel A2-70 fasteners manufacturer. The company guarantees that every product satisfies strict quality criteria, offering dependable and long-lasting fastening options. These fasteners—stud bolts, hex bolts, hex nuts, eye bolts, and eye nuts—are available in several sizes and forms to suit varied uses.
