Frequently asked questions
What does ASTM B166 cover?
Covers rod, bar and wire in the nickel-chromium-iron alloys, including alloy 600 and alloy 601, for furnace parts, heat-treating fixtures and chemical-process components.
Which grades are covered by ASTM B166?
On this site: Inconel 600, Inconel 601.
Do you supply material certified to ASTM B166?
Yes. Material is supplied to ASTM B166 with EN 10204 3.1 certificates (3.2 on request), where the mill certifies to it.
Is ASME SAB166 the same as ASTM B166?
ASME adopts many ASTM material specifications into Section II with an "S" prefix (for example SA-166). The adopted text is identical or includes stated modifications, and dual-certified material meets both.
