Normalizing for SA-516 gr 70?

[TomBarsh]

Would you say that SA-516 gr 70 is generally provided normalized in thicknesses under 1.50", even though normalizing is required by the specification only for thicknesses above 1.50"? Any experiences?

sa-516-70 is available in normalized and as rolled in thicknesses less than 1.5" here on Texas Gulf coast.

it is NOT provided in normalized condition under 1.5" unless you ask for it.

we buy it both ways and order it as rolled or normalized so our plate guys know what we want.

we don't buy it normalized unless need it for charpy exemption or service requirement.

Generally, no. This heat treatment must be requested for plate under 1.50" thickness on the PO.

It is also a substantial extra on the cost.

My experience with 2 fabricators over 8 years saw us consistently using normalized regardless of thickness. Same went for SA-105N fittings. We didn't bother buying or using any non-normalized components. Part of that was inventroy control so we wouldn't have 2 piles of everything, the other was to minimize the risk of the shop using the wrong part. Another reason was our suppliers would historically offer normalized even when we didn't need it, I think they were also using the same inventory control rationale. So, my experience 'generally' agrees with what you asked.

If you're buying the plate from a mill or service center, don't just assume it is normalized- it generally won't be unless you specify that it is.

In the case of fabricators using it anyway- that would just depend on the situation. But you'd need to ask the fabricator, not us.
