For Cylindrical Roller Bearing — ISO / DIN (Series 113) in A2 Stainless Steel, the controlling decisions are corrosion, strength and service temperature. This guide summarizes those three for A2 Stainless Steel Cylindrical Roller Bearing — ISO / DIN (Series 113) and lists every size we supply.
Why Choose A2 Stainless Steel for Cylindrical Roller Bearing — ISO / DIN (Series 113)
The most common stainless grade for indoor and general outdoor fasteners. For cylindrical roller bearing — iso / din (series 113), 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 Cylindrical Roller Bearing — ISO / DIN (Series 113) 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 cylindrical roller bearing — iso / din (series 113): (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.
