S170 alloy steel shot is described with a0.5mm reference for rust removal,polishing and sandblasting. The actual choice is Alloy Steel,grit35 and a0.2–3.0mm specification range,requiring a confirmed physical distribution.
Match the0.5mm requirement to the offer
Ask which supplied grading supports the S170/0.5mm request. The broad range and grit35 do not independently prove that every particle matches a fixed diameter.
- Alloy Steel is the actual material.
- Grit35 is the selectable label.
- 0.5mm is the parameter reference.
- Spherical form is described.
- Rust removal is a named use.
Specify hardness and heat treatment
42–53HRC and additional hardness bands need one applicable condition. Secondary-quenching wording should be supported by the actual processing and inspection records rather than treated as a performance guarantee.
Complete the peening or cleaning specification
Density is stated as a technical reference in the original data. Request composition,grading and applicable SAE J444 records,then evaluate the selected shot against the workpiece's acceptance criteria.
