Material Properties 4140/SPS
Material Properties 4140/SPS
(OP)
I have a Canadian drawing that specifies the material to be 4140/sps. I am in Australia and we are manufacturing the component and were wondering what the sps refers to.
Our 4140 grades are only single digit letters, ie: 4140 T. Can anyone help?

SPS seems to be just the designation of Atlas (Atlas Specialty Steels?) for 4140. Can't find much on Atlas' website (http://www.slater.com/stainless/index.htm)

But, the website listing is New Zealand, so the Atlas in Australia is certainly a candidate.

The 'sps' was related to Atlas Specialty Steels in Canada.
It is an old coding (not used any more) & standard 4140 T is the same as 4140/sps.
