A4-80 Bolts

A4-80 stainless steel Bolts is an austenitic, non magnetic and suitable for all the situations as A2 bolts but has 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).
