Austenitic stainless steel (A2) has the high strength of A2-100 and is a new generation of high-strength stainless steel fasteners

Exceeds the strength lacking in conventional SUS304/SUSXM7 and has the same stress corrosion cracking resistance as SUS316

A2-100 hexagon socket head screws

Material: SUS304CUN (a new generation of high-strength stainless steel produced by Datong Special Steel)

Strength level: A2-100

Tensile strength: 1,000Mpa

Guaranteed stress: 800Mpa

High strength is achieved only through drawing + cold working + aging treatment, without quenching and tempering, so there is no need to worry about aging cracks and delayed fracture

Heat resistance: 500℃

No carbon precipitation occurs even at 500-700°C.

(The usual heat-resistant temperature of 304 series (A2) is about 300°C, and the temperature when the stress is 70% is 400°C.)

Magnetic permeability: 1.01~1.03

Non-magnetic properties are better than general SUS304 (SUSXM7) bolts and equivalent to SUS316

Lightweight: By reducing the nominal diameter by three units, a weight reduction of 70% can be achieved.

Manufacturing specifications: JIS B 1176

Thread specifications: JIS B 0205

Thread series: 6g

Compatible with A2-90 external hexagonal screws.
