Chromium Equivalent Formula I Haven't Seen Before
Chromium Equivalent Formula I Haven't Seen Before
(OP)
I work as a process engineer at a machine shop, but occasionally our quality inspector will bring me a question.
Right now we have a job in the shop that requires us to provide a chromium equivalent to our customer per their spec. The formula they give us to use isn't one that I've seen anywhere before.
The CE works out to be just above what the "supplier should aim for..." I'd like to try to get the material approved, so want to calculate the nickel equivalent and show the material is still Martensitic, but I need the corresponding formula and chart.
Anyone know whose formula this is and the corresponding information?
CE= CR + 6*Si + 4*Mo - 40*C - s*Mn - 4*Ni - 30*N
