Shock & Wear Resistance Uncoated (Base Grade) with Coating Description Specifications
TOUGHEST
Shock Resistance		 DMK30 Moderate wear resistance/high shock resistance. Recommended for interrupted or unstable steel, most 300 series stainless steel, high- temperature alloys and cast iron applications. ANSI C1-C2,
ISO K25-K40,
M25-M35
  DMK30-HP High-performance medium-temperature grade. Optimum performance and wear resistance in most soft steels, soft stainless steels and cast irons.
  DMK30-GLH Premium high-temperature grade. Unbeatable performance and wear resistance in high-heat applications such as harder steels, tough stainless steels and high-temperature alloys.
MEDIUM
Shock and Wear		 DMP25   High wear resistance/moderate shock resistance, recommended for most steel and 400 series stainless steel applications. ANSI C5-C6,
ISO P25-P40
  DMP25-HP High-performance medium-temperature grade. Optimum performance and wear resistance in most soft steels, soft stainless steels and cast irons.
  DMP25-GLH Premium high-temperature grade. Unbeatable performance and wear resistance in high-heat applications such as harder steels, tough stainless steels and high-temperature alloys.
HARDEST
Wear Resistance		 DMK15
T-LAND ONLY		   Highest wear resistance with reduced shock absorption capabilities. Micro-grain carbide provides excellent edge strength for abrasive applications in nonferrous materials. Suitable for castings, aluminum and smoother cuts in tough stainless steels, high-temperature alloys and hardened steel. ANSI C2-C3,
ISO K15-K25,
M15-M25
  DMK15-HP High-performance medium-temperature grade. Optimum performance and wear resistance in most soft steels, soft stainless steels and cast irons.
  DMK15-GLH Premium high-temperature grade. Unbeatable performance and wear resistance in high-heat applications such as harder steels, tough stainless steels and high-temperature alloys.

DMP25-HP is a good first choice for most applications. Additional coatings available on request. Contact Dapra for details.
