[MW:8167] RE: 8152] 1" Sch 160 304 Stainless Steel Heavy Wall Pipe and 304L.

Hi Pat,

 

Here're some snapshots of both the materials, from SA -213.

 

Mechanical property wise there should not be any major issues.Both materials would meet 6000 psi constraints. May be it would be a good idea by the designer to check the allowable stress values in ASME Sec-II,Part-D,and approve the substitution.

 

If there're service induced corrosion issues especially intergranular corrosion testing as per ASTM-A-262, then a change of grade should be validated with new PQR on the material of same grade.

 

Thanks.

Subject: [MW:8152] 1" Sch 160 304 Stainless Steel Heavy Wall Pipe and 304L.
Importance: High

We are doing a project a project with 1” Sch1 60. The vendor ordered 304 not 304L, will the 304 meet the 6000PSI operating constraints?

 

Please advise.

 

  Sincerely;
