Re: [MW:8097] (NAS144M) equivalent of this material??

Hi Mr.Bagesh

 

I give you some more information.

 

The UNS number for 254 SMO is UNS S31254. Please look at the attached PDF file of Avesta. This pdf file also give you equivalent ASTM standards. You can do your further study on this attached pdf file.

 

Hope this fulfills your need.

 

Thanks

Hello there,

                  I have been doing a project in Korean peninsula and certainly while browsing through the piping material specification I have found NAS144M material and it has been used for the service of ACRYLIC ACID, REACTED GAS and ESTERS. The P T Rating for these services is 150 Rating.

When enquired with vendors they don't have any clue until we supply the correct material property, the contract MSD has shown 254SMO as the property of this material,

For the reference we have used SS316L for such services in other projects, but the client have rejected our request and they just resist on the material property,

Could any one have some brief on the said subject or equivalent ASTM spec or Its UNS no..

I do not have any other things to share on the same.

Regards
