Thru Sand casting, no carburising here..whats makes me firm s I have reference f acheiving strength wid even low carbon levels... TVP. 450-500 also trialed BT low impact performance..

Thanks for the suppport.. Hardening at 880 Deg C:during heating soaked at 700 Deg C for 2hours, then rose to 880 Deg C, soak for 6 hours, after completion of soaking raise 15 Deg C higher (895 Deg C) and keep it for 15minutes, then quenched in the water.Intermediate Tempering @ 550Deg C and...

thanks alot.. now can we use production furnace thermocouples for TUS ??

I just dont wanna bury this...:) Or can anybody suggest me an alternate choice of material with strength and toughness/ Heat treatment thanks

also can anybdy advise whether dis values are achievable???

we had made trials on a 60mm thick 250mm long blocks which are castings,also.n some cases after grinding some minor cracks are observed... while quenching we kept the samples on motion in water and loaded directly fr tempering
