The numbers don't lie. FEA stress analysis on an excavator grapple tine proves why you want Hardox material, every time: Factor of Safety with 50B (S355) steel = 1.19 Factor of Safety with Hardox 450 = 3.9 This was based on any single grapple tine taking a foreseeable, worst-case scenario of full bucket ram crowd force. It shows that if any extra variation to the force was present - the force not being applied straight on, or additional force from boom or dipper ram - the tine would fail using t
