Heat Tempering Furnace Tempering Oven For Swords
Tempering Machine For Sale
The third step in conditioning hardened steel for use is usually tempering. Most steels cannot be used in
the quenched condition, except for austempered steels, which are usually used in the quenched condition.
The chilling used to generate martensite makes the steel very hard, resulting in macroscopic internal stress
and microscopic internal stress, making the material very low in plasticity and extremely brittle. To reduce
this hazard, the steel can be reheated to a temperature below the low temperature transition of the A1 line.
The structural changes that occur when quenched steels are tempered are a function of time and temperature,
with temperature being the most important. It must be emphasized that tempering is not a hardening method,
but the exact opposite. Tempered steel is a steel that has been hardened by heat treatment to release stress,
soften and increase plasticity by reheating during tempering. Structural changes and changes in properties
caused by tempering depend on the temperature at which the steel is reheated. The higher the temperature,
the greater the effect, so the choice of temperature often depends on the degree to which hardness and
strength are sacrificed for plasticity and toughness.
Using the program control heating method, the temperature curve can be input into the instrument,
and the corresponding curve can be called up each time the Continuous Tempering Furnace is started, and the “RUN” key
is pressed to run, and the system will automatically execute the heating, heat preservation, and cooling
procedures, and the operation process does not require human intervention. Extremely convenient.
