Theoretical weight only. Mill rolling tolerance normally makes the delivered weight differ by 2–5%; we invoice on actual weighbridge weight.
What the metal is actually made of, as specified by the standard.
The default austenitic grade — about half of all stainless sold. Good corrosion resistance, easy to form and weld.
Strip shows the mid-point of each specified range, with iron as balance. The table below is the full specification.
