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 is an austenitic, acid proof stainless grade (usually 316 material – 316 or 316L) which has been cold worked to provide a minimum tensile strength of 800N/mm² (MPa).

A4-80 Stainless Steel Bolts grades:

Stainless steels are used for their corrosion resistance, high-temperature strength, scaling resistance, and low-temperature toughness. These properties account for their extremely wide use in practically every industry.  Austenitic Stainless Steels are designated by a 3 digit SAE Stainless Steel Grade beginning with the number 3 (e.g. 304, 316). Another common naming convention for Austenitic Stainless Steels are 18/8, 18/10, 18/0, etc. where the 18 refers to the % of Chromium and 8 to % of Nickel contained in the material.
