ALLOY STEEL FORGED ROLLED RINGS
When your operating environment demands more robust seamless rolled rings, look no further than high-quality alloy steel rolled rings from Ringmasters.
Manganese, chromium, nickel and molybdenum are some elements used to increase the performance of alloy steel after quenching and tempering. Depending on the chemistry and manufacturing process, the benefits listed below can be exhibited by forged alloy rings:
Wear resistant
High strength at high and low temperatures
Good machinability
Toughness and hardenability
Corrosion resistant
Alloy Rolled Ring Capabilities
Our team utilizes a forging process that produces seamless rolled rings with a comprehensive internal structure and circumferential grain flow, delivering superior mechanical properties. Precision rolling processes provide excellent concentricity and surface smoothness. We specialize in small-quantity orders but can also accommodate larger quantities. Our capabilities include:
