A2 Stainless Steel Wire Rope Thimble combine the dimensional form of ISO / DIN with the material properties of grade A2-70 (304): good general corrosion resistance, largely non-magnetic, service range approx. -200 °C to +400 °C. This page summarizes the grade data, its corrosion behavior in service, the comparable grades, and the sizes supplied.
Why Choose A2 Stainless Steel for Wire Rope Thimble — ISO / DIN (Series 155)
The most common stainless grade for indoor and general outdoor fasteners. For wire rope thimble — iso / din (series 155), 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 |
Galvanic & Galling Considerations
Two important notes for stainless wire rope thimble — iso / din (series 155): (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.
Comparable Grades
For Wire Rope Thimble — ISO / DIN (Series 155), 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.
