HARDENING

ThermTech refers to hardening as a process in which the entire alloy or components microstructure is being changed by a thermal process to show an overall increase in the parts mechanical properties which results in a higher hardness than the alloy or component originally had. This typically is done through quenching the parts in liquid or by aging them at an artificial temperature.

Polymer Quenching

ThermTech is proud to offer polymer hardening of steel castings when a quench faster than standard oil quenching is required. Polymer quench hardening is typically employed on castings made from low to medium alloy steel grades and sometimes for higher alloy steels with heavy sections.

Water Quenching

It is optimum for forgings to receive proper water quench hardening in order to avoid undesirable microstructural components, which can lead to low hardness, mechanical properties, and failures during service.

Age Hardening

Age hardening, also known as precipitation hardening is a low temperature heat treating process to increase the strength and mechanical properties of many aluminum alloys.
