Dear All,
Thank you for your valuable reply. I have taken a note of your answers.
The main reason to reduce the hardness of EN-24 flat is, I want to weld it at some locations. But the welding is getting cracked.
I have just taken a sample and done Normalising of it.
The hardness values before Normalising are: 249, 244 HBW.
The hardness values on the same points after Normalising are: 404, 415 HBW.
The main problem is to weld the EN-24 flat (40 X 16mm thk.) with SA 516 Gr. 70 plate (6mm thk.).
Please tell me the solution for the same.
Thanks & Regards,
Priyanka Deshmukh.

Please specify:
You intended to reduce hardness from what to what values? On what basis?
Why did you choose Normalising, what exactly did you do?
What you needed was Annealing in principle. But still a lot needs to be put together...

Dear All,I wanted to reduce the hardness of EN 24 material. For that I employed Normalising on the material.But the hardness increased instead of reducing.Can U please suggest me the reasons for this and how to reduce the hardness of the material.Thanks & Regards,Priyanka Deshmukh.
