The invention relates to a hobbing cutter ring for tunnel shield construction, and belongs to the technical field of shield tunneling machine cutters. The hobbing cutter ring for tunnel shield construction comprises a disc-shaped cutter ring body. The cutter ring body comprises a step assembling part used for being in welded assembly with a cutter hub and a working cutting edge part used for cutting. The hobbing cutter ring for tunnel shield construction is characterized in that the outer edge of the cutter ring body forms a nitriding layer by means of plasma nitriding. The shield tunneling machine cutter for metro construction has key performance indexes like excellent cutting performance, abrasion resistance and high impact toughness, the service life of the cutter can be prolonged obviously, and therefore metro tunnel construction cost can be better reduced and the construction cycle can be better shortened.
