NEW BEARING RING MATERIAL AND PRODUCTION PROCESS THEREOF

摘要

Disclosed are a bearing ring material and a production process thereof, particularly relating to a dual-metal composite pipe and a production process thereof. The bearing ring material is formed by an annular composite layer and a base layer. The composite layer and the base layer are metallurgically bonded along the radial direction of the ring. The composite layer employs a material of conventional bearing steel. The base layer employs a material of common carbon steel, low/medium-alloy high-strength steel, or stainless steel. The bearing ring material has advantages of high hardness and high wear resistance while maintaining high toughness and high impact toughness.
