Wrought S32205 from stock

We carry a comprehensive stock of UNS S32205 (1.4462, F51) as solid bar up to 16" in diameter and plate up to 3" thickness.

Machining components from solid bar or plate reduces the risk of rejection, because the wrought product form is much less likely to contain internal defects. On castings, such defects often become apparent only after machining, so considerable time and expense can be lost. Castings can still be an effective way to produce complex geometries or to reduce cost on larger components and longer production runs, but the mechanical properties of a wrought product (rolled or forged) are significantly better than those of a cast one.
