What is ASTM B906?
ASTM B906 sets the general requirements for flat-rolled nickel and nickel-alloy plate, sheet and strip. It is the nickel-alloy counterpart of ASTM A480: tolerances, finish, testing and certification rules that apply through product specifications such as ASTM B424 (Alloy 825), ASTM B443 (Alloy 625), ASTM B575 (C276, C22) and ASTM B168 (Alloy 600).

What is the difference between B906 and A480?
Both are general-requirements standards for flat products. A480 applies to stainless steel; B906 applies to nickel and nickel alloys.
Do I need to name B906 on the order?
It applies automatically through the product specification, but many buyers name it to fix the tolerance basis.
What is the current edition of ASTM B906?
The publisher's listing checked on 7 October 2026 shows B906-22 as the current edition. The edition that governs an order is the one named in the purchase order or design code. Full-text review of the current edition is in progress, so numerical requirements are not published on this page yet.
Do you supply certificates to this standard?
Yes. Material is supplied with mill test certificates to EN 10204 3.1 showing the standard, grade and heat number; 3.2 with third-party inspection on request.
