Nut Heat Treatment Process

Yes, Milo can.

Maybe you can PM him.

I am ready to help you out provided you send me the actual chemical composition of these materials as I do not remember the composition of these ASTM numbers.

NOTES

• The markings shown for all grades of A194 nuts are for cold formed and hot forged nuts. When nuts are machined from bar stock, the nut must additionally be marked with the letter 'B'. The letters H and M indicate heat treated nuts.

HI,

thaks for your reply but i required the heat treatment detailed procedrue that how to make the nut of above ASTM and grades,

All these Materials are P1. You have the parameters mandatories in ASME I, ASME IX, and also in ASME B31.1 and B31.3.

Wich one are you using?

i can provide the ASTM standard but heat treatment procedure detailed required if any one know plz help ... you may give me your email so i will send it,

thanks,

Kindly send all the details about the materials. I will give the heat treatment schedule.
