Ferritic Nitrocarburizing

FNC is a process performed on carbon steel bar stock or parts. Carbon and nitrogen are diffused into the steel, creating a “white layer” which creates a protective seal. This will benefit parts in applications where there is increased wear, fatigue, distortion, or corrosion.

BENEFIT

  • High level of wear resistance
  • Low distortion
  • Improved fatigue properties
  • Greater corrosion resistance
  • Uniform appearance

Isothermal Annealing

Isothermal anneal is a two-stage process involving austenitizing the material, first at preferred temperature and subsequently cooling to and holding at a specific temperature to complete the transformation. This process is used for achieving specific microstructures and hardness in certain grades of steel that are not possible with normalize, or full anneal processes.

BENEFIT

  • Relatively soft ferrite-carbide aggregate micro-structure for good machinability
  • A more cost-efficient process with comparable micro-structures to batch type annealing.

Footer Logo

Normalize

Normalizing is a type of annealing in which steel is austenitized (heated above a critical temperature), held for a specified time, and then cooled in air.

BENEFIT

  • Improved machinability of steel
  • Reduction of residual stresses
  • Microstructural homogenization
  • More uniform response to subsequent processing

Footer Logo

Pickle and Oil

This is a two-step process that involves removing contaminants from the surface of the steel such as scale, stains or rust. Once the contaminates are removed from the steel, the part is submerged in hot oil, which displaces any water from the surface of the steel creating a rust preventative layer.

BENEFIT

  • Removes scale from the heat-treating process
  • Removes rust contamination to improve post processing appearance and oil

Footer Logo

Quench and Temper

The quench and temper process provides strength and toughness throughout the part being processed. It is a two-stage heat treat process that includes hardening and tempering.
This process is used in applications where the tensile strength, fatigue resistance and impact strengths are of the utmost importance. Quench media can include oil, polymer, water, gas, or salt.

BENEFIT

  • Increased strength
  • Flexibility of hardness range
  • Increased toughness
  • Superior wear and abrasion resistance

Footer Logo

Sawing

Sawing is needed for steel grades that are prone to cracks during the forging process. Cutting bar stock to specific weights or lengths reduces cracking and subsequent stresses on the steel while being forged.

BENEFIT

Sawing is needed for steel grades that are prone to cracks in both shearing and further forging operations.

Footer Logo

Shearing

Shearing is done to convert steel bars into billets to be formed into forgings. This process is known to be quicker and less expensive than traditional sawing methods.

BENEFIT

  • Shearing is the first step in converting bars into forgings by producing billets.
  • It is also a faster process than sawing.

Footer Logo

Shot Blast Cleaning

Scale on parts must be removed for proper machining and increased tool life. Shot blast cleaning removes scale from any of the heat treat processes by impinging the parts’ surface with hard steel shots.

BENEFIT

  • Removal of heat treat scale, forging scale, rust, or other surface contaminates
  • Increased surface area of steel, for subsequent coating operations
  • Polishing
  • Work Hardening of the steel’s surface

Footer Logo

Spheroidize Anneal

Spheroidize Annealing is a low temperature process that produces spheroidized carbides. For a given grade of steel spheroidized microstructure provides the lowest possible hardness compared to others. With the low hardness, spheroidized microstructure lowers flow resistance in material which is ideal for cold formation.

BENEFIT

  • This is typically used with cold formed parts and high alloy steel to reduce hardness for machinability.
  • Provides the required microstructure for cold forming processes.
  • Preferred for machining of high alloy steel grades by reducing hardness.
  • Cold forming can be performed at room temperature with no need for heating billets or parts

Footer Logo

Stress Relieve

Operations such as rough machining and cold forming can generate residual stresses in parts. If not removed, these stresses can release themselves in an uncontrolled fashion causing dimensional issues. In stress relieving, parts are taken to and held at an appropriate temperature to relieve the residual stresses created in the prior operations.

BENEFIT

Operations such as rough machining and cold forming can generate residual stresses in parts. If not removed, these stresses can release themselves in an uncontrolled fashion causing dimensional issues at subsequent operations. This process is required on welded material to keep them stress-free.

Footer Logo

Zinc Phosphate & Lube Coat

The coating process starts with proper surface preparation of the parts by immersing them in a series of chemicals. Phosphate and lube coating of parts are performed to facilitate cold forming operations. Phosphate coating also produces base for rust preventive material. Phosphate and lube coating is suitable for several types of low carbon and low alloy steels.

Zinc phosphate coated material can also be dipped in oil to create a protective layer on the steel. This provides rust prevention for an extended period.

BENEFIT

  • Phosphate and lube coating of parts are performed to facilitate cold forming operations
  • Phosphate coating also provides base for rust preventative material

Annealing of Aluminum

Annealing consists of heating the material to 500-800 F in a similar fashion to solution heat treating, but there is no quench. The material is either removed from the furnace to cool at room temperature, or a specialized furnace cooling method is utilized. This results in a soft material.

BENEFIT

  • Soft material is ductile and can be formed, stamped, bent, or machined more easily than tempered material
  • Aids in prevention of stress fractures in forming operations

Footer Logo

Artificial Aging (Aging)

Artificial aging of aluminum consists of heating the material to 225 – 500 F for a specified period of time. This process typically follows solution heat treating to further harden material.

BENEFIT

  • Material strength after artificial aging is substantially greater than strength given by solution heat treatment alone
  • Vastly improved tensile properties
  • Artificial age cycles can be adjusted to meet specific properties
  • Reduced internal stresses resulting from solution heat treating

Footer Logo

Core Burnout / Thermal Sand Removal / Sand Bakeout

Sand castings sometimes retain sand cores that are too large to safely heat treat. Large sand cores can cause steam explosions when they quench, therefore, if sand core weight is =/> 10% of the casting weight, it requires a core burnout. The material is put through the solution process but does not quench. Sand becomes free flowing and can be dumped or blown out.

BENEFIT

  • Prepares the parts for solution heat treating
  • Ensures safety of personnel by preventing steam explosions
  • Offers increased cleanliness of finished sand-cast parts

Footer Logo

HyperQuench

Quenching is the most critical step of solution heat treatment, and the industry-leading 5-second quench delay offered by our HyperQuench furnace delivers the best outcome for mechanical properties. This short delay also meets requirements of many Aerospace specifications. Our HyperQuench furnace features a small work cube which allows for cost effective processing, making it perfect for research and development projects and prototype work.

BENEFIT

  • Highest mechanical properties available due to short quench delay
  • Cost effective processing
  • Up to 25% glycol quenchant concentration for increased dimensional control
  • Fully electric, conforming to requirements of AMS2770

Footer Logo

Precision Air Quench

The precision air quench involves a three-step process. First, parts are heated to solution temperatures, then quickly transferred to the air quench chamber. High air velocities uniformly cool parts and prepare the parts for the final step in the process. Parts are then artificially aged for 1-10 hours to increase hardness and mechanical properties.

BENEFIT

  • Distortion control and dimensional stability
  • Ability to more effectively process thin walled aluminum castings and stampings
  • Improved mechanical properties
  • Increased toughness
  • Uniform quenching without vapor layer

Footer Logo

Solution & Quench

Solution heat treating of aluminum consists of heating the material up to 800-1,100 F for a specified period of time, and quenching in water, glycol (AKA polymer), or forced air. Parts move from the solution furnace into a quench tank where the media is 50-200 F. This harsh contrast between temperatures is what allows the material to take on the hardness from solution heat treating.

BENEFIT

  • Increased material strength
  • Improved tensile properties
  • Improved machinability through decreased ductility

Footer Logo

Solution, Quench, & Age

Solution heat treating of aluminum consists of heating the material up to 800-1,100 F for a specified period of time, and quenching in water, glycol (AKA polymer), or forced air. Parts move from the solution furnace into a quench tank where the media is 50-200 F. When the material has cooled sufficiently in the quench media, it is transferred to an age furnace where it is heated to 225 – 500 F for a specified period of time.

BENEFIT

  • Material strength after artificial aging is substantially greater than strength given by solution heat treatment alone
  • Vastly improved tensile properties
  • Artificial age cycles can be adjusted to meet specific properties
  • Reduced internal stresses resulting from solution heat treating

Footer Logo

Stress Relieving of Aluminum

Stress relieving of aluminum typically consists of heating the material to 225 – 500 F for a specified period of time, but processes vary greatly and can require temperatures up to 1,000F.

BENEFIT

  • Reduces existing internal stresses, resulting in lower propensity for stress fractures in machining, bending, or other forming operations
