Reinforcement Plate (H-028) manufactured in A2 Stainless Steel (A2-70 (304)) are dimensioned to GB/T 6170 / ISO 4032. The sections below give the mechanical and physical properties of the grade, its behavior in corrosive and elevated-temperature service, and the full size table.
Why Choose A2 Stainless Steel for Reinforcement Plate (H-028) — GB/T 6170 / ISO 4032 (Series 065)
The most common stainless grade for indoor and general outdoor fasteners. For reinforcement plate (h-028) — gb/t 6170 / iso 4032 (series 065), 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 Reinforcement Plate (H-028) — GB/T 6170 / ISO 4032 (Series 065) in indoor and general outdoor service. In chloride-bearing environments (marine air, road salt, swimming pools) consider stepping up to A4 (316).
Comparable Grades
For Reinforcement Plate (H-028) — GB/T 6170 / ISO 4032 (Series 065), the alternative stainless grade is A4 (316). 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.
