[MW:16591] Re: Standard Reference for Hardness of A 516 Gr.70

Dear All,

In addition to trailing mail.

The Vessel is used for storage of Helium liquid.

The PWHT was done according to UCS-56.

The Thk. of Shell & d/e are 40 & 50mm respectively.

The clients wants to know acceptance reference standard of Hradness.

We checked after PWHT & found in range from 150 to 200 HB.

Please provide reference acceptance standard for the Hardness to convince client.

Awaiting your reply.
