Durability of Stainless Steel Bars

The stainless bar has a low surface friction. The bars could stay stable, no matter how the temperature changes, no matter you place them indoor or outdoor, as they’re UV resistant.

Chlorine ion is the most corrosive hazard to the metals, unless you drop the Stainless Steel Barbell into the sea, the bar will corrode for less than 1mm within 100 years, so you see the span life of the bars.

The anneal hardness is over 230, while the cold pull hardness is beyond 260, the surface is definitely stiff, abrasion resistant.

So you could store and use them under any condition. In a word, if you want to invest only one barbell in lifetime, stainless steel bar is your choice. Anyway the whip is not that good, you would need to consider about that issues.
