This low-melting-point salt bath cooling medium is composed of highly pure nitrates and nitrites, with strictly controlled impurities such as carbonates, sulfates, and chlorides. Special processing methods ensure its stable cooling performance and long service life.
Advantages
● Resistant to hardening into clumps due to moisture absorption;
● No vapor film cooling phase, significantly reducing quenching deformation;
● Cooling performance is adjustable through moisture control, providing uniform surface hardness and preventing soft spots during quenching;
● Compared to quenching oil, it achieves a deeper effective hardened layer;
● Resistant to aging and degradation, with a long service life.
