GCr15/52100/SUJ2 Bearing Steel Plates

Поделиться:


GCr15 is a high-carbon chromium alloy steel, for its versatility, is used in a variety of mechanical applications. 

In the annealed condition this steel is comparatively easy to machine, yet very high hardness, abrasion 

resistance can be developed by heat treatment to make steel particularly suitable for applications

requiring extreme wear resistance.
