trying to match up some stainless tubing, what all does “ASTM A269 B90 SMLS” mean on this one?

Question by: Gary B on Jul 30, 2025, 12:09 PM

In plain terms, it tells you the tubing is stainless made to the ASTM A269 standard, it is seamless (SMLS), and the “B90” callout is part of how it is identified in the product name for that spec and style.
