Hardening and tempering using water and oil as quenching agents
The pre-heat treatment comprises normalizing treatment, and the quenching-and-tempering heat treatment comprises quenching treatment and tempering treatment.
full quenching and tempering
quenching and tempering to improve mechanical properties.
Annealing, normalizing, quenching and tempering are the "four torches" in the whole heat treatment, among which quenching and tempering are closely related and often used together.

The beautiful real hamon on the blade is also result of the differential cooling of the blade (quenching and tempering).
The beautiful real hamon on the blade is also result of the differential cooling of the blade (quenching and tempering).
To achieve the hardness, high chrome steel ball must use high temperature quenching and tempering.
The inventive part preferably undergoes solution treatment, quenching and tempering, T6 or T7.
Hardening and tempering of the strip steel is needed to achieve the correct finish and to meet the properties required by the end user.
The risk of hardening cracks during re-hardening of quenched and tempered steel can be reduced by soft annealing prior to the hardening and tempering process.
guaranteed impact value in the quenched and tempered or blankhardened condition

Quenched and Tempered Steels - Part 2: Technical Delivery Conditions for Unalloyed Quality Steels
At least one pipe end part of the cut steel pipe is subjected to diameter reduction and is then quenched and tempered.
NOTE 2 For the purposes of simplification, the term "quenched and tempered" is, unless otherwise indicated, used in the following also for the austempered condition.
The cast iron is formed by casting, autenitizing, quenching, and tempering the alloy.
It is acceptable to conduct intermediate heat treatment (quenching or a combination of quenching with tempering) between the steps (4 and 5).
Preferably, the pipe is subjected to a quenching-tempering treatment.
The profiled edge (1) is at first rolled, then quenched and subsequently tempered over its whole cross-section.
Soak and return Heating of steel at an austenization temperature followed by a liquid hardening or by a pulverization, then reheat to an appropriate temperature and a cooling in a liquid or in the air.
– All through the manufacturing process (Heating, Forging, Quenching and Tempering), we control all the parameters that affect the quality of the final product.
The invention concerns a mechanical component resulting from hot process or cold process deformation of a steel without quenching and tempering treatment subsequent to forming.
The impregnated carrier (12) is then sintered with a ceramic substrate material, the carrier (12) being removed by evaporation.
The compression spring can be lifted after quenching and tempering: preloading the spring so that it deforms across the spring when the spring can be deformed during operation.
The annual capacity of the line is 250,000 tonnes, which means that one third of NLMK Clabecq’s products will pass through the quenching & tempering line.
The annual capacity of the new line is 250,000 tonnes; this means that one third of the production of NLMK Clabecq will pass through the Quenching & Tempering.
