I am a bit late to this thread, but I see you have decided to keep it.
That is probabally a good call. I dont know how much other grapples cost, but if yours is indeed made entirely out of T1 steel, you should have no issues at all.
T1 is also know as A514 steel. You can google that if you want. But the 3/8 A514 is a significant bit stronger than even 1/2" A36 mild steel that most other grapples are probabally built from.
Mild steel has a 60ksi-80ksi tensil and only a 36ksi yield strength. A514 tensil and yeild is BOTH in the 110ksi range:thumbsup: That makes it VERY tough, it is NOT brittle, and it is very abrasion resistant.
Some common uses are bridges and cranes (for the strength) and dozer blades and BH buckets for wear resistance. A514 is used because a smaller dimension of steel can be used and still be just as strong. Thus saving weight.
My only concern is that if it is indeed made all from A514, it should be welded with a 110 series filler. Like a 11018 rod and not 7018. Or a ER110 wire for mig.
It can be welded with the weaker filler, and it wont cause any issues with the A514, just note that the welds will be weaker than the parent metal. Probabally not an issue on your grapple thought. Because the way most stuff is designed, the welds dont have to have 100% of the strength. Other parts will bend/break first due to leverage and the way things are designed.
Do you have any pics BTW, or did I miss them?
