I have a customer who was haveing problems with the small 1/16 316l stainless mandrels melting and bending.
Wondering if I have a bad batch of stainless or if something else may be going on.
I using mandrels from the same lot with my hot head on propane with out issue, as most oxy/fuel setups produce a lot more BTUs expecialy working hard glass.

What might be going on?

I send a message to the customer and am waiting to hear back on what setup they are useing and other details.

At this point I'm trying to trubble shoot the problem.
This is the first time I have hear of this problem, after selling nearly 30lbs from the same material, batch number and everything.
