305 Stainless Steel

Products We Offer:

We also provide safety grating, hex metal, FRP grating, and custom fabrication of all of our products.

Principal Design Features: 305 has the lowest work and strain hardening rate of all the austenitic stainless steels. It was designed for maximum formability. It combines good strength and corrosion resistance and is readily available in strip and some bar sizes from the mills.

Applications: Any application requiring maximum formability such as spun or deep drawn eyelets, barrels, shells, cold headed rivets or screws will work well.

Machinability: Slow speeds and heavy feeds are recommended to combat the material’s tendency to glaze during machining.

Welding: Most of the common fusion and resistance methods can be used here. Filler metal, if necessary, should be AWS E/ER308. Oxyacetylene welding is not recommended.
