With the rich industry experience and knowledge, we are able to manufacture and supply a wide range of Vacuum Hardening Furnaces. The offered Vacuum Hardening Furnaces are made by using high quality material in compliance with all the national and international quality standards and norms and are durable in nature and sturdily constructed.

Hardening is a typical heat treatment process combining heating to specific temperatures (mostly above 900 °C) and direct fast cooling or quenching of the part. The requirements are selected to change the materials’ structure partially or completely into martensite.
