bullet Harden & Draw / Quench & Temper

The thermal process operation used to increase the hardness & strength of steel. Performed by heating material to the proper austenitizing temperature & holding for sufficient time to achieve partial of complete transformation to martensite, then quench in sutable medium. Tempering is performed by reheating the material to a temperature below the transformation range then cooling under suitable temperature. Tempering improved ductility & toughness and reduces the quecnhed hardness to desired hardness.

bullet Masking

Painting of a No Carb. Paint to prevent Carburizing on an area of the material.

bullet Deep Freeze (Cryrogenic)

Exposing to suitable subzero temperatures for the purpose of obtaining desired conditions or properties such as dimensional or micro-structural stability. When the treatment involves the transformation of retained austenite, it is usually followed by tempering.

bullet Stress Relieving

A process to reduce internal residual stresses in a metal object by heating the object to a suitable temperature and holding for a proper time at that temperature. Followed by cooling slowly enough to minimize the development of new residual stresses. This process may be applied to relieve stressed induced by casting, quenching, normalizing, machining, cold working, or welding.

bullet 100 % Inspection

The hardness testing of all part in a job that has be heat treated.

bullet Certification

Documentation providing the heat treating processed performed on a job along with the final hardness if required. Certification will also show the customer's specifications and upon request show the time and temperature of the heat treating process.

bullet Furnace Charts

Charts that have information populated by the furnace as load are being heat treated.

bullet Brass

Heat treating of Brass material as per customer specification.

bullet Age Hardening / Aging / Precipitation Hardening

A time-temperature-dependent change in the properties of certain alloys. For each alloy susceptible to aging, there is a unique range of time-temperature combinations to which it will respond. The result of precipitation form a solid solution of one or more compound whose solubility decreased with decreasing temperature.

bullet Normalizing

A thermal treatment consisting of heating to a suitable temperature above the transformation range and then cooling in still air. Usually employed to improve toughness or machinability, or as a preparation for further heat treatment

bullet Annealing

A thermal cycle involving heating to, and holding at a suitable temperature and then cooling at a suitable rate, for such purposed as reducing hardness, improving machinability, facilitating cold working, producing a desired microstructure, or obtaining desired mechanical or other properties.

bullet Air hardening & Oil/Water Tool Steel

A Harden & Draw / Quench & Temper that involves the heat treating of various type of tool steel.

bullet Carburizing

A process that consists of absorption and diffusion of carbon into a solid ferrous alloy by heating to a temperature above the upper transformation temperature of the specific alloy. Heating is done in a carbonaceous environment. This produces a carbon gradient extending inward from the surface, enabling the surface layer to be hardened to a high degree by quenching from a temperature 200 degree F below the carburizing temperature.
