For blind pop rivet in A2 Stainless Steel, the controlling selection factors are corrosion exposure, strength requirement and service temperature. The grade data for A2 Stainless Steel (A2-70 (304)) is summarized below together with every size supplied.
Why Choose A2 Stainless Steel for Blind Pop Rivet — GB/T 12618 / ISO 15983 (Series 098)
The most common stainless grade for indoor and general outdoor fasteners. For blind pop rivet — gb/t 12618 / iso 15983 (series 098), this matters when good general corrosion resistance is the primary requirement.
Mechanical & Physical Properties
| Grade designation | A2-70 (304) |
|---|---|
| Magnetic response | Largely non-magnetic |
| Service temperature | approx. -200 °C to +400 °C |
| Corrosion characteristic | Good general corrosion resistance |
Corrosion Behavior in Service
A2 (304) gives excellent atmospheric and most-water corrosion resistance and is the most common stainless for Blind Pop Rivet — GB/T 12618 / ISO 15983 (Series 098) in indoor and general outdoor service. In chloride-bearing environments (marine air, road salt, swimming pools) consider stepping up to A4 (316).
Galvanic & Galling Considerations
Two important notes for stainless blind pop rivet — gb/t 12618 / iso 15983 (series 098): (1) stainless can gall on stainless threads under load — use a thread lubricant or anti-galling compound, especially for M6 and below; (2) when joined to aluminum or galvanized steel, stainless can drive galvanic corrosion of the less-noble metal in wet service — isolate with a coating or sleeve where appropriate.
