Our Alloy Steel Forged Rings are through hardening alloy rings, these rings are recognised for their competent wear resistance against hostile elements, they can be further surface hardened to enhance their toughness and wear resistance.
We supply Alloy Steel Forged Rings with excellent machinability for the locomotive, automobile, cranes for the offshore industry, etc.
We have built a reliable product portfolio over the span of 30 years through the conservative use of resources and a careful monitoring of market trends and demands.
