[MW:604] Re: 13% Cr steel valve trims

Dear Ravi,

 

If a steel contains 13% Cr. it means it is stainless Steel.

The material specifications provided by your vendor are adequate. You may even use SS304 grade.

Gents,

Please share your views on following:

"As per specs valve trims are required to be of 13% Cr steel" no further details given w.r.t. material specs nor clarified with client then.
However vendor has supplied A276-316 for stem and A351 CF8M for disc.

Are above acceptable as per spec of 13% cr steel.

As per client's interpretation of 13% Cr steel means AISI 410 or equivalent but not 316.
 

Best regards,

Ravikiran
