need help shearing blade material selection
(OP)
dear all,
i am working on design & mfg. of TMT bar Cutting machine. I have problem in the material selection of shearing blade and its appropriate hardness. i have used S1 ( K455 ) material and hardness is 56 to 58 HRC. But i found failure like blade breaking and edge damages while cutting.The TMT bar Is of 60 to 80 Kg/mm2.
Can anybody will help me regarding the balde material selection and the hardness process?
Matter is too urgent. Please....
Thanks & regards,
Sainath Pohnerkar

RE: need help shearing blade material selection
...and 60-80 kg/mm2 is a shear strength or lineal mass density?
...if a shear strength, is it comparable to ~85,000 psi?
How thick is the "tmt", how thick is the blade?
Shearing 85 ksi material sounds like a tough job for any tool steel...
