A4-80 Bolts are austenitic, non-magnetic, and suitable for all situations as A2 stainless bolts, but have the added advantage of being suitable for marine solutions. Often called Marine Grade stainless steel. The molybdenum increases the corrosion resistance to withstand attack from many industrial chemicals and solvents, and of course, chlorides. Used in the production of inks, photographic chemicals, surgical implants, and the marine environment.
The designation A4-80 derives from “A,” meaning the material is a cold-worked austenitic stainless, divided into 5 grades (1-5, hence the “4”) according to material characteristics. The “80” denotes the minimum tensile strength to be met by the material (actually the bolt, screw or nut after manufacture). A4-80 Bolts is an austenitic, acid-proof stainless grade which has been cold worked to provide a minimum tensile strength of 800N/mm² (MPa).
