Old Material callout
(OP)
Hi guys,
Working on an old (same age as me) hydro plant and need to know what material I'm seeing. The print says Steel 125/105 16/50. I assume the 125 is ultimate strength of 125,000 psi and the 105 is yield strength of 105000 psi. The 16 would be percent yield but what the heck is the 50?????
Thanks,
Jeff

For proper material selection, you need to know the product form (including size), service and environmental conditions to select a comparable grade of material.

If you want more corrosion resistance (and spectacular erosion resistance) you should look at duplex stainless steels. Alloys like LDX2101 are available as cold finished bar. They would have plenty of strength and great corrosion resistance.
