Salt Bath Processes. Salt Bath Hardening can offer advantages over alternative hardening and tempering methods. Molten salt is often considered the 'ideal' heat treating medium. When parts are immersed in the molten salt, heat is transferred by direct contact to the surface



Cryogenic hardening is a cryogenic treatment process where the material is cooled to approximately −185 °C (−301 °F), usually using liquid nitrogen. It can have a profound effect on the mechanical properties of certain steels, provided their composition and prior heat treatment are such that they retain some austenite at room temperature. It is designed to increase the amount of martensite in the steel's crystal structure, increasing its strength and hardness.

Induction heating is the process of heating an electrically conducting object (usually a metal) by electromagnetic induction, through heat generated in the object by eddy currents. An induction heater consists of an electromagnet, and an electronic oscillator that passes a high-frequency alternating current (AC) through the electromagnet.

Controlled Atmosphere Brazing and Heat Treating. ... The furnaces are approved for aerospace use and used for a wide range of work including vacuum stress relieving, vacuum annealing, solution treatments, aging processes and high-temperature vacuum brazing.

Quality Control

Our Quality Control laboratory is one of the most complete and modern in the industry and is complete with the following.

Newage Indentron hardness testers- This tester is the most modern tester on the market today. With this we are able to furnish printouts of hardness readings, x-bar charts, graphs, histograms, as well as calculating Standard Deviation and many other statistical equations.
Newage MT-90 Production Micro-hardness tester - This is a 1000 gram micro-hardness tester that has all of the printout capabilities of the Indentron hardness tester as well as performing and printing profiles of parts being tested.
Antonik Knoop micro-hardness tester - This is a very diverse tester with load capabilities from 10 to 1000 grams.
Brinell Tester capable of loads up to 3000 kilograms

All of our hardness testers are inspected daily and certified by factory personnel every four months to assure your parts are within your specifications when you receive them.

On top of hardness testing equipment our Q.C. Laboratory is also equipped with microscopic evaluation equipment with photographic attachments, A magnaflux, several pieces of equipment for checking dimensions and a Leco carbon determinator. All of our furnaces are run with shim stock and checked daily to assure a correct carbon level is being maintained.

We are also certified and inspected periodically by Ford Motor Company, Pratt & Whitney, Lockheed, Parker Hannifin, McDonnell Douglas, General Signal to name a few. Our operations also conform to the latest revisions of AMS-H-6875, AMS-H-6090 AND AMS-2750E, as well as AMS-2759. We are a currently  ISO 9001-2015 certified.
