Hello
We have taken hot rolled and annealed stainless steel and forged it
We are interested to find out its macro structure ?
Please comment
Please consider this previous related RG discussion for its possible interest: https://www.researchgate.net/post/What_is_a_good_etchant_for_316_stainless_steel
Generally Nital is used-
Nital- Ethanol (100 mL) Nitric acid (1-10 mL ) Conditions-Seconds to minutes
I think Nital is suitable etchant
use 10% oxalic acid (in 100 ml water 10 g oxalic acid) you have to do electrolytic etching (2V for 10 s)
Instead of checking only the mRNA level, I want to check the active protein level of MMP-1 in Liver tissue from mice. How can I do that?
