We are proud to offer the following heat treating services |

This treatment consists of heating the work-piece to an appropriate hardening temperature, which is dependant on the type steel, holding for sufficient time to ensure the material is at the correct temperature and then rapidly cooling it (quenching). This can be air, oil, water, molten salt, or a pressurized inert gas, such as nitrogen. The type of quench used is dependant on many things, mainly the type of steel or shape of the part.
Following quenching, the material is at its hardest but brittle condition and requires another treatment (tempering, or drawing), to reach desired properties. This is done by re-heating the part to a specific temperature and holding for a specific time. Tempering is generally done between 300 and 1250 F. |

With specially designed presses we can flatten parts ranging in size from 1 to 48 inches. |

Annealing is the heat treatment used to soften metals, to allow metalworking operations to be performed without damaging machine tools and dies. Annealing increases machinability, reduces internal stresses, and prepares material for hardening operations. Full annealing consists of heating the material to above the critical temperature and slowly cooling it. |

Austempering uses molten salt as the quench medium. By quenching material in molten salt approx. 700F as a result banite is formed which is a tougher structure than martensite. This increases ductility and reduces product distortion. Austempering is a great for springs and stampings |

Marquenching® or martempering of steel involves quenching the steel in hot oil or salt at 300-400F, and holding it in the quenching medium until the material is equal to the temperature of the salt or oil. This eliminates distortion of the workpiece, normally found in conventional quenching. |
