Detailed Product Description

ASME SA266 GR.2 Disk And Ring

ASME SA266 is a specification that defines the requirements for carbon steel magnetic particle inspected forged steel disks and rings. This specification is often used in industrial applications where high-quality, durable components are required.

The material covered by this specification is carbon steel. It is designed to be suitable for use in environments where magnetic particle inspection (MPI) is necessary to ensure there are no surface or near-surface defects.

The parts must be forged and then machined to achieve the final dimensions and shape. The forging process helps to develop the grain structure and mechanical properties of the steel.
