philip in china Posted January 27, 2013 Share Posted January 27, 2013 I was clearing up and doing a bit of painting around the shop today. I noticed that the two Rhino anvils seem to rust less than my Brooks and less than some of my loose tools. Would that be because of the nickel and chromium in the alloy of the Rhino anvils? All the stuff is in the same shop, same humidity and temperature etc. Quote Link to comment Share on other sites More sharing options...
eric sprado Posted January 27, 2013 Share Posted January 27, 2013 Funny: I was just noticing the same thing with my Papa Rhino and my old Hay Budden. I'm in the Oregon Coast Range and EVERYTHING rusts. I usually cover my anvils at night but forgot to the other day and was out of my shop for a couple of days. the Rhino was still shiny and lots of other things in shop were not!!

njanvilman Posted January 27, 2013 Share Posted January 27, 2013 Correct me if I am wrong, but Nickel and Chromium are the main alloying elements of Stainless Steel. I am sure that even a small amount in the total will help with the oxidation problem. Quote Link to comment Share on other sites More sharing options...
jmccustomknives Posted January 27, 2013 Share Posted January 27, 2013 After checking, they are cast from a tool steel. The addition of the nickle and chromium retards rust somewhat compaired to simple carbon steels. It should be noted that steel doesn't become stainless until it reaches 13% chromium. It didn't come out and say but it's probably a 41XX series. Quote Link to comment Share on other sites More sharing options...
philip in china Posted January 28, 2013 Author Share Posted January 28, 2013 So the alloy elements in the Rhino anvils probably does retard rust a bit then. I suppose older anvils were just a simple carbon steel rather than an alloy steel. Quote Link to comment Share on other sites More sharing options...

I know they are "as hard as a mother in law's heart and as tough as a mother in law's tongue". They are not alloyed to anything like the levels of stainless of course.
