Twas a lot easier to find this time. 2050 is the product number of PCS, it's a tapped support pillar used in molds. The actual material is 1040. Here are the specs on 1040 and 4140:
1040: https://www.azom.com/article.aspx?ArticleID=6525
4140: https://www.azom.com/article.aspx?ArticleID=6769
The machinability of 1040 is 60, compared to 4140's 65. As to hardness, they are very close to each other.
It also has one other property that makes it better than 4140. I have 2": round 1040, I don't have 2" round 4140!!!
