Quenching and Tempering

The process of Quench and Tempering is important because it improves the mechanical properties, hardness and toughness of the alloy material. The oil and gas drilling industry has for years used quench and tempered steel tubulars for well casing. The quench and tempering process can be affected by several things which may be beyond the control of the heat treater. Some of the common elements are steel type, rolling method, forming processes, weldings, sizing and seam normalizing. Tubular Services has three Quench & Tempering Lines with Power Parts Induction Heating to meet all your needs.

Quenching

The quenching process starts with heating the steel to a temperature at which it changes the grain structure from ferrite to austenite. It then rapidly cools (quenches) to force the austenite to transform to another shape called martensite. This is the high strength structure of steel and the ultimate goal of the process.

Tubular Services uses induction heating method to develop instantaneous heat within the steel part. Tubular Services takes much care in the quenching process to ensure the best quenching rate to prevent any distortion from the thermal shock.

Tubular Services uses plain water in the carbon steel quenching operation.

Tempering

Tempering completes the heat-treating process. It helps relieve the stress induced by quenching. Tubular Services uses induction tempering to achieve the desired hardness and mechanical properties.

Higher temperature induction tempering can often achieve superior toughness properties. Tubular Services takes pride in our experience and care in minimizing variations in the end product.
