Milling Grades For Stainless Steels and Other Metals: YBM251, YBM253, YBM351 (Toughness: YBM251 < YBM253 < YBM351)Grade: YBM251 (ISO Class: P15-40, M10-M30)
: TiCN + Thin Al2O3 + TiN (CVD) Coated High-Strength Carbide
With strong and high-toughness substrate and coating, this grade is suitable for medium through rough milling of stainless steels and steels.
Grade: YBM351 (ISO Class: P25-P40, M20-M35)
: TiCN + Thin Al2O3 + TiN (CVD) Coated High-Toughness Carbide
With a highly engineered gradient and ultrafine carbide substrate and nano coating, this grade offers great high cutting edge strength and wear resistance. Inserts with this grade are highly recommended for rough milling of stainless steels and steels.Grade YBM253 (ISO Class: M10-M30)
TiCN + Ultrafine Al2O3 (CVD) Coated High-Strength Carbide
The grade has a combination of gradient substrate and multi-layer coating composed of TiCN and ultra fine Al2O3 that offers excellent strength and toughness. It is the primary grade for stainless steels milling.
