INTRODUCTION
Salt baths have many advantages over other heat treatment processes, viz Rapid rate of heat transfer in the salt bath gives higher output
Uniform and accurate control of temperature can be available through out the bath and the components.
The following Salts for various processes of Heat Treatment are available with us.
SALTSFOR CARBURISING
ALFACARB I
Salt for Carburising with Working Range 760-950C (ICI Equivalent `Rapicarb-H)
ALFA CARB II
Salt forCarburising with WorkingRange 800-950C (ICI Equivalent - `Rapicarb-S )
B. NEUTRAL SALTS
ALFA 660 Working Range 660-900C ( ICI Equivalent - `NC 660 )
ALFA 660 is usedfor hardening various tool steels, preheating high-speed steels hot work
Steels prior to hardening with ALFA 970. ALFA 660 is denser than ALFA 720, but less soluble in water. ALFA 660 does not ecarburize the charge. The working range
can be increased upto 1000 C by covering the molten salt with ALFA
ECONOMISER. (225 gm per 100 kg ).
ALFA 720 Working Range 720 900C ( ICI Equivalent - WS 720 )
ALFA 720 is a salt which neither carburise nor ecarburize the steel and it readily dissolves in water.
ALFA 830 Working Range 830 1100 C ( ICI Equivalent HT 830 )
ALFA 830 along with ALFA ECONOMISER (130gm per 100 kg ) can be used for hardening tool steel, hot working dies, high Cr steel etc. ALFA 830 can be used safely in ceramic lined electric ecarburi furnace. The floating ALFA ECONOMISER on the surface can be mixed by stirring with a stirrer.The bath can bedesludged for every 8 hours and topped up with ALFA 830 and ALFA ECONOMISER in proportion.
ALFA 970 Working Range 970 1350C ( ICI Equivalent HS 970 )
ALFA 970 can be used to harden high- speed, hot working, tool steels etc. ALFA 970 neither ecarburize nor allow the formation of scale on the surface of the components.
C . SALTS FOR QUENCHING AND TEMPERING
ALFA 540 Working Range 540-700C ( ICIEquivalent QS 540 )
ALFA 540 can be used for minimum distortion and less risk of cracks than in oil quenching.
ALFA 495 Working Range 495 700C ( ICI Equivalent QS 495 )
ALFA 330 Working Range 330 535C (ICI Equivalent - TS 330 )
ALFA 330 can be used for the heat treatment of ALUMINIUM ALLOYS. After solutionising in ALFA 330, the same can be precipitation hardened in ALFA 150.
10. ALFA ECONOMISER ( Refer above )
11. ALFA 220 Working Range 220 550C (ICI Equivalent TS 220 )
12. ALFA 150 Working Range 150 550C (ICI Equivalent - TS 150 )
ALFA 150 can be used for MARTEMPERING & AUSTEMPERING of steels.
