Agree actual grade and dimensions before choosing a finish for this custom stainless tube.

Requested material

The title names 321 and 310S alongside 304 and 316L, while the detailed grade list has a different scope. Confirm the requested designation with traceable evidence rather than assuming every titled grade is available.

OD and surface

The actual thickness option is 2.5 mm and the OD field is 50 without a unit. Clarify compatible dimensions and select BA or No.1 finish rather than interpreting both as one supplied surface.

• Actual stainless designation
• OD value and unit
• Compatible wall thickness
• Finish and usable length
• End and inspection requirements

Supply acceptance

Lengths of 3, 6 and 12 m or customization are described. Define service tests and actual availability; quick shipping wording does not establish delivery timing, global supply, pressure performance or chemical compatibility.
