These High Tensile A2- 70 Fasteners contain a combination of molybdenum, titanium, nickel or copper alloy for enhanced or increased properties such as strength, corrosion resistance, formability and so on. The A2-70 grade derives from the letter “A”, meaning the material is cold-worked austenitic stainless, divided into five grades. The “70” denotes the minimum tensile strength to be met by the material.
Moreover, A2-70 is an austenitic, acid-proof stainless grade 304 and 304L material mainly used for cold work to provide a minimum tensile strength. It is the most versatile and widely used grade for any critical condition.
It has excellent forming and welding characteristics. These A2-70 Fasteners are highly resistant to crevice corrosion in warm chloride environments and to stress corrosion cracking. These high-graded A2-70 Fasteners provide excellent tensile strength, superior finish, longer life, higher durability and flexibility to sustain in higher pressure and temperature conditions. These A2-70 Fasteners come in various shapes, sizes, thicknesses, etc.
