Material Specifications (CAN/CSA-G40.21)

Material Specifications (CAN/CSA-G40.21)

Material Specifications (CAN/CSA-G40.21)

(OP)
Is anyone familiar with CAN/CSA-G40.21.  I need to know how CAN/CSA-G40.21 Grade 300W for channels, angles and plates compares to an A36 designation.  Does A36 meet the CAN/CSA-G40.21 Grade 300W requirements?

RE: Material Specifications (CAN/CSA-G40.21)

I haven't the info directly with me but as I believe (if memory serves) if the service temperature is < 250ºF then the two are equivalent, afterwards A36 diverges.

Today is gone. Today was fun.
Tomorrow is another one.
Every day, from here to there,
funny things are everywhere.

RE: Material Specifications (CAN/CSA-G40.21)

300W has a higher yield (44 ksi) than SA-36 (36 ksi).  In my opinion, 300W is an overall stronger material.  Anywhere SA-36 material is specified, 300W is generally an acceptable substitute (not necessarily every application).  However, I would not automatically accept SA-36 in lieu of 300W due to the strength differences.  Both are common grades of carbon steel.  I have found the 300W very commonly used in Canada and SA-36 more commonly used in the United States.  Also, in addition to the strength differences, there are minor chemistry differences.  This link has a very brief comparison of the two.
