DIN1.4923 Forged Steel Rings Turbine Guide Ring Forgings Forging Blanks Rough Machining
Forged Steel Rings Introduction
Forged Steel Rings on one of our radial ring rollers is southwest aluminum specialty. The process for ring forging for the seamless rolled forged ring involves cutting a hole out of a forging material.The rolled forged rings offer improved concentrically and smooth surfaces as compared to plate burn-outs, or butt welded rings.
