S390 round steel shot enquiries should specify grading and hardness class. Confirm the proposed S390 supply before applying a broad particle-size description to another S-series option.

• Steel is the material option.
• Six S-series grit choices are selectable.
• Round is the stated form.
• Shot peening is the use.
• SAE J444 is a reference.

Confirm the S390 diameter

The technical particle description is 2.5mm. Ask which S designation and distribution it applies to rather than assuming every option shares that size.

Choose a hardness class

GP, GL and GH ranges appear alongside another hardness expression. Obtain the applicable specification instead of combining them into one range.

Request relevant evidence

Provide the intended peening requirements. Standards, ISO and quality wording need supply-specific documents rather than an automatic compliance or performance guarantee.
