High performance cemented carbides for molding；Standard Specification For Square Material and Standard Specifications Of The Rings. Also we can produce the your drawing of ring.

100% raw material;
Hip sintered, high hardness, high wear resistance;
Tunable residual stress
Electrochemical corrosion resistance

Polarization curve (corrosion current reduced, corrosion rate decreased significantly, corrosion resistance improved significantly)
