Induction Hardening

Lone Star has a fully equipped Induction Department. We have 4 state of the art N/C touch screen vertical scanners.
For deep case induction hardening we have a 125kw (10khz) power supply coupled with a vertical scanner capable of processing material up to 10 ft in length with 112" centers.

Benifits of Induction

The hardening process is used to produce a localized surface hardening of an area that needs wear-resistance, while retaining the toughness of the original structure as needed elsewhere. The depth of induction hardened patterns can be controlled through choice of induction-frequency, power-density and interaction time

Continuous Line Heat Treating

We installed our first continuous line in 1998 which proved to be a great addition to our facility. To increase capacity, a second continuous line was added in 2005. Both lines are Bickley gas fired barrel type furnaces with high pressure water quenching and in line tempering, capable of running both bar and tube to high mechanical properties.
We have the capability of running Bar stock from 3" to 10" up to 42' long and Tube 3" to 11" up to 42' long.
Heat Treating in a continuous furnace gives you the added benefit of:
Stress Free Material.
Temperature Uniformity.
Control of Heating & Cooling Rates.
Repeatability of Process.
100% Inspection.
Metallurgical Quality.

After processing all material is tested by our in house ISO 17025 approved metallurgical lab for destructive & none destructive testing.
