Thanks all of you
As per B898
1.1 This specification covers plate consisting of a base metal to which is bonded, integrally and continuously, on one or both sides a layer of one of the following: titanium, zirconium, tantalum, niobium, and their alloys. The material generally is intended for pressure vessel use.
Where as Pressure vessels are dealt by ASME.
ASME Sec II B does not list this under Section II B.
Does this mean we can still use this for Pressure vessels?
If no how can ASTM declare that the material is good for Pressure Vessels.
It is my understanding that it is ASME who decideds the use of ASTM material and if suitable for Pressure vessel adopts into ASME Sec II B.
Am i missing something???
