Material
Brand and identification of the original batch.
QUALITY CONTROL
Control of material, structure, hardness, dimensions and surface of parts.
QUALITY CONTROL
SENNAI materials include spectral analysis, metallography, magnetic particle testing, hardness, coating, roughness and dimensional testing. Not every method applies to every position: the composition is confirmed in the task.

WHAT TO CHECK
The characterization must have a clear method and criterion.
Brand and identification of the original batch.
Metallography or magnetic particle testing if required.
The hardness, layer or coating in a specified area.
Dimensions, shape and roughness of working surfaces.
HOW THE WORK IS CONSTRUCTED
The input characteristics cannot be restored only by the final measurement. Therefore, some of the data is recorded on the material, some after heat treatment, and the geometry and surface after finishing.

RESULT
The form of the protocol, the sample and the composition of accompanying documents are determined before production, and are not promised equally for all products.
BEFORE AGREEMENT
The list of checks depends on the material, technology and function of the product. Before production, characteristics that must be documented, critical dimensions and sample volume are determined. Control methods are not combined into one common promise: for each position, the applicability, criterion and format of the result are recorded.
Mark, certificate or agreed method of identification.
Critical dimensions, tolerances, shape and relative positions.
Hardness, layer, surface or coating as specified.
Sampling, labeling, protocol and non-conformity rules.
NEXT STEP
Indicate special characteristics, sampling, record format and required documents.
