SP-55 is for steel castings only. Do not use it for wrought, forged, or fabricated parts (use MSS SP-93 or other standards).

MSS SP-55 provides a visual quality standard for steel castings used in pressure-containing applications. Unlike dimensional or mechanical testing standards, SP-55 focuses exclusively on surface discontinuities—including cracks, shrinkage, sand inclusions, porosity, and cold laps. ⚠️ Important: Always obtain the official MSS SP55

The standard uses reference photographs to define acceptable and non-acceptable surface conditions. These photographs are essential to the standard; without them, the written text has limited practical use. This is why working with a high-quality MSS SP55 standard PDF—complete with clear images—is critical.

The PDF includes reference plates (typically 8–12). Each plate shows:

Common categories: | Plate | Irregularity Type | |-------|------------------| | A | Shrinkage | | B | Gas porosity | | C | Sand inclusions | | D | Cracks / cold shuts | | E | Surface pitting |
