01tundra Posted March 3, 2016 Share Posted March 3, 2016 I have access to pretty much as many ASTM A193 B7 threaded studs as I want for free, but I'm not sure if they're worth collecting? They are generally 7/8" to 1-1/8" diameter and usually around 6" long. The best I can tell from online searches is that it's very close, or equal to, treated 4140, but I haven't found much mention of forging with it. They are made from Chromium-Molybdenum Ferritic Alloy Steel with a tensile strength of 125 KSI and a Rockwell Harness of 35 HRC in a plain finish. Looks to me like it wouldn't be very good for knives and such, but maybe OK for general forging? Thanks. Quote Link to comment Share on other sites More sharing options...
ThomasPowers Posted March 3, 2016 Share Posted March 3, 2016 Too much work for general forging unless you use a powerhammer but sounds great for tool making for many types of blacksmithing tools where tough is good. Do they quench harden any? Tongs that are tough but can be cooled in water would be nice... Quote Link to comment Share on other sites More sharing options...
John McPherson Posted March 3, 2016 Share Posted March 3, 2016 A193 B7 is just quenched and tempered 4140/4142. Up to .49 % carbon, not a great edge holding steel, but better than a RR spike. It should make great punches, drifts, etc. without too much change in profile. Lacking a power hammer or striker, I would not want to spend a lot of energy and time turning them in to something else.

Frosty Posted March 3, 2016 Share Posted March 3, 2016 Sounds like good tong steel to me IF you have a power hammer to draw it to usable and you'd have to lose the threads or they're just a long line of cold shuts awaiting to be born. I think a bucket of them wouldn't be a bad thing to have back in a corner, good trading stock if nothing else. Frosty The Lucky. Quote Link to comment Share on other sites More sharing options...
01tundra Posted March 3, 2016 Author Share Posted March 3, 2016 It sounds like I need to accept some amount of this gift, especially since my new stiker friend has been found - thanks guys. Quote Link to comment Share on other sites More sharing options...
