Tolerance Guidelines

Material tolerances not listed below shall be in accordance with the ASTM, ASME, or AMS specification to which the material was produced and certified.
Shearing

(up to 10mm thick)

  • Standard plate and sheet length and width tolerance is +/- 1.5mm
  • Upon request, special processing for sheared sheet can be done with width and length.
  • Precision shearing is also available upon request.
  • Diagonal tolerance is 5mm maximum on sheared items.
Abrasive Saw Cutting - Pipe and Bar

Standard abrasive saw cut plate and sheet.

  • Width and Length: +3mm/-0mm
Plasma - Plate and Sheet

(3mm to 50mm thick)

Standard plasma cutting length and width tolerances stated are "Top Face" typical.
NB - tolerances reversed on I.D. cuts.

  • Up to 19mm thick: +3mm/-0mm
  • 19mm to 40mm thick: +6mm/-0mm
  • 40mm to 50mm thick: +10mm/-0mm
Waterjet - Plate and Sheet

(Maximum thickness 100mm)

Standard waterjet processing length and width tolerances are as follows:

  • Up to 12mm thick: +/- 0.75mm
  • 12mm to 25mm thick: +/- 1.00mm
  • 25mm to 75mm thick: +/- 2mm
Laser - Plate and Sheet

(Maximum 10mm thickness)

  • Standard laser processing length and width tolerances are as follows:
    • +/-0.25mm
