A query about hardening of metal using quenching process. To get the hardness of 600 BHN the time span of 10 mins are required and want to reduce the time span of the work without affecting the hardness. The quenchant used is water. What changes should I make in the quenching process?
That's interesting. How does the hardness of the metal change with different quenchants?
The hardness of the metal is affected by the cooling rate of the quenchant. Generally, a higher cooling rate leads to higher hardness because it reduces the time that austenite has to transform into a softer phase. However, if the cooling rate is too high, it can also lead to cracking and distortion of the metal. The choice of quenchant depends on the type of steel, the desired hardness, and the properties of the quenchant itself.
