Material specification page for blind pop rivet in A4 Stainless Steel. Covers the grade designation (A4-80 (316)), corrosion and magnetic behavior, comparable grades and their trade-offs, and the sizes available to GB/T 12618 / ISO 15983.
Why Choose A4 Stainless Steel for Blind Pop Rivet — GB/T 12618 / ISO 15983 (Series 098)
Specified for marine, coastal and chemical applications. For blind pop rivet — gb/t 12618 / iso 15983 (series 098), this matters when superior, including marine and chloride environments is the primary requirement.
Mechanical & Physical Properties
| Grade designation | A4-80 (316) |
|---|---|
| Magnetic response | Largely non-magnetic |
| Service temperature | approx. -200 °C to +400 °C |
| Corrosion characteristic | Superior, including marine and chloride environments |
Corrosion Behavior in Service
A4 (316) adds 2–3% molybdenum to the A2 (304) composition, which dramatically improves resistance to chloride-pitting corrosion. For Blind Pop Rivet — GB/T 12618 / ISO 15983 (Series 098) in marine, coastal, swimming-pool or food-processing environments, A4 is the default selection.
Comparable Grades
For Blind Pop Rivet — GB/T 12618 / ISO 15983 (Series 098), the alternative stainless grade is A2 (304). A2 (304) suits general indoor and outdoor service; A4 (316) adds molybdenum for marine and chloride environments. Where higher strength matters more than corrosion, switch to plated alloy-steel class 8.8 or 10.9.
