Introduction
Analysis of the core content of the standard
Stainless steel shot is the core consumable of shot peening, and its standardized production directly affects the quality of surface treatment. The JB/T 8354.5-2015 standard establishes a technical specification system from three dimensions: material properties, process parameters, and quality control.
Comparison Analysis of Specification Systems
| Comparison Dimensions | Cylindrical Particles (Type C) | Spherical Particles (Type S) |
|---|---|---|
| Particle Size Range (mm) | 0.3-2.5 | 0.3-2.5 |
| Weight Standard (50 Particles/g) | 0.03-5.62 | 0.03-5.34 |
| Surface Roughness Control | Better | General |
| Fatigue strengthening effect | General | Better |
Detailed explanation of key technical indicators
Hardness control: The standard stipulates three optional hardness ranges (200-290HV/290-380HV/380-510HV). The aviation field mostly uses the high hardness specification of 380-510HV to improve the blade strengthening effect.
Defect control: The limit requirement of crack particles ≤5%. The actual measurement of an automotive parts manufacturer shows that exceeding the standard will increase the probability of micro scratches on the workpiece surface by 300%.
Industry application implementation suggestions
- Selection and matching: The shipbuilding industry should use M/SSS/S/160 spherical particles, taking into account both cleaning efficiency and surface finish
- Process verification: New batches need to be fully tested according to the GB/T 19816 series standards
- Storage management: Humidity control ≤60%RH can effectively prevent agglomeration problems
Standard evolution background
This standard was first published in 2015, filling the gap in domestic stainless steel shot standardization. Compared with the SAE J441 standard, it adds ultra-fine specifications (0.3mm) and hardness grading requirements, which are more suitable for precision manufacturing needs.
