Structural Shapes - Nucor-Yamato Steel
Roll wear, along with deformation in the mill and the plasticity of hot steel may also cause variations from the published dimensions of rolled structural shapes. Therefore, to meet camber or sweep tolerances, they may need straightening by the producer. Other tolerances are subject to negotiation with Nucor-Yamato Steel.

Mill tolerance in Seamless Pipe - Every cloud has a silver ...
Mill tolerance comes from the manufacturing process of seamless pipe. Welded pipes have a tolerance as well, but usually is not a mill tolerance and it is much lower because it's more easy to get high accurancy when producing steel plates. On the other hand welded pipes need to consider the weld joint efficiency factor, to take in account the ...

Pipe Mill Tolerance in accordance with ASTM, ASME B36.10M is considered to be ±12.5% of the nominal pipe wall thickness, tn. That is to say: if you have a pipe supplied with a nominal thickness tn, and you need to measure the actual thickness, you can find that there is a deviation reaches about ±12.5% tn.
