Salt bath soft nitriding (Isonite®)

ISONITE is salt bath soft nitriding process, providing various properties such as fatigue resistance, heat resistance, wear resistant, low distortion and high hardness, which can be applied to several type of steel such as carbon steel, sintered metal, low alloy steels, stainless steels, cast irons and high alloy steels. Thai Parkerizing can provide ISONITE process according to various type of metal and customer’s requirement.

Salt bath nitriding (ISONITE®)

ISONITE is the salt bath soft nitriding process, generate a compound layer and diffusion layer by nitrogen and carbon diffusing into the steels. 

The compound layer improves hardness and wear resistance, the diffusion layer increases fatigue endurance limit without changing the toughness of the core. 

ISONITE treatments can be applied to several type of metal material such as carbon steel, sintered metal, low alloy steels, stainless steels, cast irons and high alloy steels.

Moreover, Thai Parkerizing Co., Ltd. can be applied Salt Quench technique: SQP and QPQ to raise anti-corrosion and wear resistance properties of parts after ISONITE process.

SQP
SQP is a process that carry out oxide film over the compound layer after ISONITE process to increase wear and corrosion resistance.

QPQ
QPQ is a process that added after ISONITE and SQP to increase wear resistance, anti-corrosion and improve fatigue.
