Overview
Industrial gases are used in many heat treatment processes to create an atmosphere suited to the material and process requirements. Controlling the gas atmosphere can help limit oxidation, protect surfaces, support consistent product quality and meet the technical requirements after treatment.
Heat Treatment Applications
01.Protective Atmospheres and Annealing
In heat treatment and annealing processes, gases are used to create a protective atmosphere and limit the exposure of materials to oxygen and undesirable components in the air. This helps reduce the risk of oxidation, discolouration or adverse effects on surface quality after treatment.
An appropriate gas atmosphere is particularly important for components requiring a high level of surface stability and finish quality.
02.Nitriding
Nitriding is a surface treatment process used to improve the properties of metal components, particularly in applications requiring surface hardness, wear resistance and dimensional stability after processing.
During nitriding, control of the gas atmosphere plays an important role in supporting the quality and uniformity of the treated surface layer.
03. Low-temperature Treatment
Low-temperature treatment is used in certain processes to support the stabilisation of material properties after processing. With its ability to create very low temperatures, liquid nitrogen can be used in applications requiring cryogenic cooling or temperature control according to specific technical requirements. This application is considered according to the material characteristics, equipment used and treatment objectives of the respective customer.
