Crusher Screen?

Doubtful it is a crusher screen- metal appears to be too soft and way too thin. Most likely a shield missing its mounting brackets. Looks to be stainless, or poss even titanium? If it seems very light- its titanium. Heavy? It is stainless steel or painted steel. Could also be a strainer for use in a flow setting often used to slow down material like grains. This was custom made in a shop, by hand, not a production piece. (You can tell by the marks, no metal grade stamp, etc)
