Torque Increment process in Bronze C-95500 materialApril 22, 2019
Q. We are in a business of grounding systems, and in grounding system you might be aware of hot line clamps. I have a design & material finalize. I am only achieving a torque of 400 Lb in the design and my customer requirement is 600 lb in same design and material. Photo I have attached you can see in that I need torque in part where nut is located.
Design and material is specified so we are finding a process which can increase the torque; all the annealing process which are possible in the material from normal to solution temperature we have done but same result.
How can I increase the torque after the sand casting? Material is Bronze grade of C-95500. We got the hint that there is a finishing process which increase the torque by process itself. Can you help me with the process?viral Sojitra

A. Hi, Viral. Thank you for the highly detailed question which hopefully a reader can answer. Despite your strong effort to make it clear, I still don't quite understand what you mean be 'achieving a torque'. What happens if you put a wrench on that nut and try to apply 600 in-lbs of torque? Does the casting break at 400 in-lbs?

Q. Yes Ted, at 400 lb in it is breaking and we want 600 lb inch to fulfill the customer requirement.viral sojitra [returning]

Teflon coating the fastener or the assembly might allow for higher torquing. No harm in trying one assembly.
