hi to everyone
im new in this forum and HHO subject
i had done a lot of research about cell configurations, electrolites and other stuff and a im very excited about HHO,so i decided to build a hydrogen generator. looking for materials more specific stainless steel i found that 304 SS is too expensive here in my country(im from colombia) about 200 dollars for 40 x 80 inches plate which is sold only in this size. I found another stainless steel 430 SS which is too much cheaper and sold in smaller pieces.

here is the composition of each SS:
304 SS

C Si Mn P S Cr Ni
≤0,07 ≤1,00 ≤2,00 ≤0,045 ≤0,015 17,00-19,50 8,00-10,50



430 SS

C Si Mn P S Cr
≤0,08 ≤1,00 ≤1,00 ≤0,040 ≤0,015 16,00-18,00

no Ni

What do u think guys? could be a good replacement?
thanks
