WHY CHOOSE FREEWAY CORPORATION STAINLESS STEEL WASHERS?

Are stainless steel washers good?

Stainless steel washers are a good choice in multiple industries. Especially due to their corrosion resistance properties. Along with this, stainless steel washers can come with many different surfaces finished included dull, shiny, brushed, and polished.

What is the difference between zinc and stainless steel washers?

The difference between zinc and stainless steel washers is the substrate of material. Steel washers have the ability to rust, so they are normally plated with zinc in order to protect from corrosion. Stainless steel washers are already corrosion resistance because of the base material having corrosion resistant properties.

What is the difference between 300 series and 400 series stainless steel washers?

The differences between 300 series and 400 series stainless steel washers stem from their composition, corrosion resistance, strength, weldability, and typical applications. 300 series washers are preferred for environments with high corrosion risk, while 400 series washers are suitable for applications where strength and cost-effectiveness are more critical.
