We’re often asked how we arrive at our quoted prices since many heat treatment companies have a £/kg rate, i.e. they charge by the kilo weight being treated.

In general this kilo rate is suitable for standard treatments, such as case hardening, nitriding, hardening and tempering, as a given quantity of energy is used to heat a mass of material to prescribed temperatures and then quench to a prescribed cycle. Handling and jigging, etc. are factored into this rate, although adjustments do sometimes need to be made due to the complexity of some parts.

However, the processes for flame and induction hardening treatments are very similar to machining operations and we have always believed that the most reliable and economic estimates are obtained by using similar costing techniques. Therefore, our prices are always quoted on a per component basis.
