The quality of our machined plate rings, discs and flanges separates Stainless Processing from it's competition. Our ability to machine up to 120.00" OD covers virtually all of our customers needs. One of our machined items is the plate flange. It is a more economical alternate to the ANSI forged flange. Please check out our plate flange page for more information. For hard to find grades and gauges, machined all over forgings may be offered. Possibilities are unlimited when it comes to machining circular items with our full line machine shop! Standard tolerance ±1/32, ±.005 or closer upon request.
