Salt specially developed as aquenching medium for mar tempering and aus tempering. Also used for low tempering after hardening. Tempering salts contain nitrates/nitrites and Should never mixed with cyanide since they react violently if heated together. The sludge formation is negligible and carry over losses are also very less. However, daily removal of slag is recommended and topped up with fresh salt to store original chemistry. The addition.
