A4-70 is an austenitic, acid-proof stainless grade that has been cold-worked to provide a minimum tensile strength. The name A4-70 derives from the letter “A”, which means the material is cold-worked austenitic stainless, divided into five grades according to the material characteristics. And the number “70” denotes the minimum tensile strength to be met by the material. These fasteners are present in various diameters, shapes and sizes.
A4- 70 Fasteners are formed using Grade 316. Grade 316 is the standard molybdenum-bearing grade. The use of molybdenum alloy in manufacturing this fastener gives better overall corrosion-resistant properties. It has resistance to pitting and crevice corrosion in various atmospheric conditions, chloride, and other corrosive media.
Grade 316L is often more resistant to carbide precipitation and can be helpful in the specific atmospheric range. It has excellent forming and welding characteristics. Also, these grades cannot be hardened by thermal treatment efficiently. Cold working produces enhanced levels of tensile strength properties. A4-70 Fasteners contains a combination of several alloys, but it consists of Chromium, Molybdenum and Nickel element in a higher quantity. These fasteners possess excellent chemical and mechanical properties.
