Dyna-Blue® is a low temperature (800° - 1200° F) surface treatment. The process is generally referred to as “ferritic nitrocarburizing” and it yields two, distinct metallurgical characteristics:

  1. White/ compound layer with hardness up to 1880 Vickers (75+ Rockwell C)
  2. Nitrogen enriched diffusion zone, .002 - .010" deep to support the compound zone

The metallurgical properties are diffused into the base material, therefore, the process is not a coating and it will not flake, peel or chip off.
 
WHAT ARE THE BENEFITS OF DYNA-BLUE®?
 
  • High wear resistence-surface hardness, typically greater than Rockwell “C” 75.
  • High corrosion resistance: up to 1000 hours when combined with our NITROWEAR M dry film lubricant.
  • Lower co-efficient of friction, as low as .03
  • Low dimensional variation: .0001"-.0002 growth per side
  • Anti-galling & anti-sticking properties
  • Resists soldering, heat checkingand washout on die cast dies
  • Resists wear from glass filled plastics up to 10 times longer than nitriding or chrome
  • Maintains excellent microfinishes
  • Not limited by component geometry or line of sight.
  • 100% environmentally friendly.
  • Better weldability than traditional nitriding or ion nitriding.
  • Capacity 42"x 134" and 75"x 100" : up to 10 tons
  • Hard surface hardness maintains ductility, durability testing has shown that DYNA-BLUE® can bend up to 90° without cracking.
  • Overnight service is available

MICRO-TEC=Multi-layer Coating Technology
 
 
 

MICRO-TEC is a proprietary combination process where DYNA-BLUE® 70+HRC and a low temperature hard coating, 85+HRC are combined. The DYNA-BLUE® process provides a good hard support layer beneath the coating and also adds an extra layer of wear resistance after the coating wears off. This combination gives superior wear resistance as compared to CVD coatings without the distortion. The combination process has been successfully used with Titanium Nitride, Titanium Aluminum Nitride and Chrome Carbide, just to name a few.

NITROWEAR®
 
 
 

NITROWEAR® is a proprietary and patented combination process where increased corrosion resistance above and beyond the corrosion resistance of DYNA-BLUE® is needed. The process incorporates proprietary coatings/oils after the part has been processed with DYNA-BLUE®.

  1. NITROWEAR-1 DYNA-BLUE® plus water soluble oil for corrosion resistance for salt spray resistance of approx. 60-72 hours per ASTM B-117, which is better than 409 stainless steel.
  2. NITROWEAR-2 DYNA-BLUE® plus an oil/wax emulsion dip for corrosion resistance of approx. 96-120 hours per ASTM B-117.
  3. NITROWEAR M: DYNA-BLUE® plus dry film coating for lowest co-efficient of friction
    and highest corrosion resistance, up to 1000 hours salt spray resistance per ASTM B-117.

Maximizing the Heat Treating Process using a 10 Bar Vacuum Furnace and Fluidized Bed Tempering:
 
 
 

To maximize tool life of die cast tooling, hot form tooling, forging or casting tooling the heat treating process must be optimized In order to optimize the mechanical properties inherent In the steel. The 4 most critical factors we closely control are:

  1. Controlling the heating rate to control distortion with 12 thermocuples placed in the core and surface of the tools.
  2. Maximizing the austenitizing temperature to insure solution of vanadium carbides without causing grain growth.
  3. Maximizing the quench rate to increase fatigue strength, hot strength and wear resistance.
  4. Tempering in Fluidized Bed Furnaces to insure tools are not undertempered or overtempered. Other batch ovens/ furnaces are slow heating so that by the time the core is up to heat the surface may be overtempered or the core may be undertempered. The Fluidized Bed Furnaces heat uniformly and quickly, much like that of a pot of boiling water.
 
WHAT STEELS CAN BE VACUUM HARDENED?
 

The furnace was designed to harden tool steels, such as (M-2, M-4, T-15, H-11,H-13, D-2, S-7, 420SS, CPM9V,10V, etc).
