DIN ES isO 3506-1: 1997 specifies the mechanical properties of bolts, screws and nuts made of austenitic (amongst others) stainless steels, when tested over an ambient temperature range of 15o C to 25o C.

Prosaic Steel and Alloys, through its Manufacturing, trading and Export division High Tensile Stainless, supplies a range of material that enable fastener manufacturers and others to produce products that meet or exceed the properties required in the above standard. Material to meet the properties of A2-70 is one element of our product range.

The designation A4-80 derives from "A” meaning the material is a cold worked austenitic stainless, divided into 5 grades (1-5) according to material characteristics (see Annex B of DIN ES isO 3506-1: 1997 for full description of each grade). The "70” denotes the minimum tensile strength to be met by the material (actually the bolt, screw or nut after manufacture).

Therefore, A2-70 is an austenitic, acid proof stainless grade (usually 304 material - 304 or 304L) which has been cold worked to provide a minimum tensile strength of 700 N/mm2 (MPa).

Grade 304 is the standard "18/8" stainless; it is the most versatile and most widely used stainless steel, available in a wider range of products, forms and finishes than any other. It has excellent forming and welding characteristics. The balanced austenitic structure of Grade 304 enables it to be severely deep drawn without intermediate annealing, which has made this grade dominant in the manufacture of drawn stainless parts such as sinks, hollow-ware and saucepans. For these applications it is common to use special "304DDQ" (Deep Drawing Quality) variants. Grade 304 is readily brake or roll formed into a variety of components for applications in the industrial, architectural, and transportation fields. Grade 304 also has outstanding welding characteristics. Post-weld annealing is not required when welding thin sections.

Excellent in a wide range of atmospheric environments and many corrosive media. Subject to pitting and crevice corrosion in warm chloride environments, and to stress corrosion cracking above about 60°C. Considered resistant to potable water with up to about 200mg/L chlorides at ambient temperatures, reducing to about 150mg/L at 60°C.

Solution Treatment (Annealing) - Heat to 1010-1120°C and cool rapidly. These grades cannot be hardened by thermal treatment.
